ES6 in Production [JSConfUY2015]

The document summarizes Carlo Sciolla's blog post about using Clojure to interact with the Alfresco content repository. It shows how to write a function in Clojure to loop through all nodes in a repository and print their names, and compares the Clojure code to the equivalent Java code. It also discusses some Clojure concepts like immutable data structures, macros, and sequence processing that make the Clojure implementation more concise and functional than the object-oriented Java code.

Clojure introduction, concepts, functional programming elements. Real world usage. Clojure community heros.

This was a talk given at HTML5DevConf SF in 2015. Ever wanted to write your own Browserify or Babel? Maybe have an idea for something new? This talk will get you started understanding how to use a JavaScript AST to transform and generate new code.

Swift is a new programming language introduced by Apple for iOS and Mac app development. It has the best of both C and Objective-C with speed, interactivity and modern conventions.

ECMAScript6: Novedades y navegadores que dan soporte a ECMAScript6. Presentado por ings.: Alex Adriá y Mario García

A quick introduction to Swift, the new language Apple introduced in WWDC14 to create apps for iOS and OSX

The document provides an introduction to Clojure by listing various resources about Clojure including websites, videos, papers and books. It discusses key aspects of Clojure such as its Lisp heritage, functional programming principles, namespaces, polymorphism using protocols and multimethods, and concurrency features using Software Transactional Memory. The document also compares Clojure to other Lisps and outlines Clojure's basic syntax where code is represented as data structures.

This document discusses using Clojure to interact with the Alfresco content management system. It provides an example of using Clojure to loop through all nodes in the Alfresco repository and print their names. It then explores translating the Java code into an idiomatic Clojure implementation using features like macros, immutable data structures, and Clojure's powerful seq library for processing sequences. The document aims to illustrate how a functional programming language like Clojure can provide benefits for working with Alfresco.

Take a look to Swift, if you've been developing for iOS in Objective-C many things may look familiar, maybe just "upgraded". If you're a first timer diving into iOS development we strongly recommend you to understand first the basics of Cocoa.

The document discusses several interesting features of the Swift programming language, including type inference, mutability, optionals, named parameters, enumerations, switch statements, closures, and generics. Type inference allows variable types to be inferred from values rather than explicitly declared. Optionals handle the absence of values and can be conditionally unwrapped. Closures provide block syntax similar to Objective-C but with additional optional syntax. Generics allow structures to work with different types rather than a single type.

This document discusses patterns in object-oriented programming versus abstractions in functional programming. It provides code examples of using functional abstractions like the IO monad and type classes in Scala. The examples demonstrate how to construct programs by composing functions, handle errors, and test programs using the IO monad. Known applications of functional abstractions include using monoids for accumulating values, functors for mapping over data types, and monads for modeling effects. The document advocates thinking algebraically by focusing on properties, extending closed data types, and building applications from small, composable abstractions.

This document summarizes new features in Swift 2 including guard/defer statements for flow control, protocol extensions for default implementations, and error handling improvements like throwing and catching errors. It also mentions Swift becoming open source with its source code released under a permissive license and contributions accepted from the community, including ports for Linux. Nest is provided as an example open source Swift web framework project on GitHub.

The document provides an introduction to Swift programming concepts including variables, constants, data types, operators, control flow, functions, arrays, dictionaries, classes, structs, enums and more. Code examples are provided to demonstrate how to declare and use variables, constants, functions, arrays, dictionaries, classes, structs and enums in Swift. Key Swift concepts like optionals, tuples, protocols and generics are also briefly covered through code snippets.

This document discusses functions and closures in Swift. It provides examples of defining functions, passing functions as arguments, returning functions from other functions, capturing values from outer scopes within closures, and using lazy initialization to avoid strong reference cycles and memory leaks. Specifically: 1. It shows functions taking other functions as arguments and returning functions. 2. It demonstrates using closures to define functions inline and passing them to other functions. 3. It provides an example of capturing external values within closures and how to avoid strong reference cycles when doing so. 4. It explains how to use lazy initialization with the @lazy property wrapper to lazily initialize properties and avoid memory leaks.

The document discusses working with code abstract syntax trees (ASTs). It provides examples of parsing code into ASTs using libraries like Esprima, querying ASTs using libraries like grasp-equery, constructing and transforming ASTs, and generating code from ASTs. It introduces aster, an AST-based code builder that allows defining reusable AST transformations as plugins and integrating AST-based builds into generic build systems like Grunt and Gulp. Aster aims to improve on file-based builders by working directly with ASTs in a streaming fashion.

This document provides a summary of an introduction to the Clojure programming language. It discusses what Clojure is, its timeline and adoption, functional programming concepts, concurrency features using Software Transactional Memory, the Lisp ideology it is based on including homoiconicity and its macro system. It also provides an overview of getting started with Clojure including using the REPL, basic syntax like symbols and keywords, data types, sequences, functions, and Java interoperability. Resources for learning more about Clojure are also listed.

The document discusses abstract syntax trees (ASTs) and parsing of code. It provides examples of parsing JavaScript code into tokens and then building a syntax tree. It also discusses common JavaScript parsers like Esprima and Acorn, and AST specifications like ESTree. Homomorphic parsing is shown where code and AST are equivalent. Common uses of ASTs include transpilation, linting, minification, and code transformation.

This document discusses ECMAScript 2015 (ES2015), also known as ES6. It provides examples of new ES2015 features like arrow functions, template literals, classes, and modules. It also discusses how to set up a development environment to use ES2015, including transpiling code to ES5 using Babel, linting with Eslint, testing with Mocha, and generating coverage reports with Istanbul. The document emphasizes that while ES2015 is fun to explore, proper tooling like linting and testing is needed for serious development. It concludes by noting ES2015 marks a transition and thanks the audience.

I gave a talk at ReactFoo Mumbai about the history of how we arrived at the module bundlers we have today, specifically webpack. We walked through a live coding demo where I built a working webpack configuration for a working Vue application and then talked about the future of webpack.

The document discusses the Java Compiler API, which was standardized in Java 6. It provides two ways to programmatically compile Java source code: simple and advanced. The simple approach demonstrates how to retrieve the Java compiler, run it to compile a source file, and then access the compiled class. The advanced approach provides access to error messages and more options. The document also covers using printf formatting with custom formattable classes by implementing the Formattable interface.

Quick overview of ecmascript 2015 features with examples how to rewrite es5 code into es6 presented at Pixers Academy.

This document discusses exploring ES6 features including classes, modules, arrow functions, template literals, destructuring, iterators, generators, and proxies. It provides code examples of implementing classes, modules, and other features in ES5 syntax compared to the cleaner ES6 syntax. It also discusses setting up a development environment with Node.js, npm, and Babel to use ES6 features and introduces more advanced topics like proxies and generators.

1. ES6 modules allow for modular code through the use of export and import statements. Exports define what is public in a module, and imports access those exports from other modules. 2. Prior to ES6, many patterns existed for modular code like anonymous closures, revealing module pattern, CommonJS, and AMD, but they had various issues. 3. Webpack and Rollup are module bundlers that take modules defined with import/export and bundle them for usage in browsers which do not natively support modules. They also convert ES6 code to ES5 for browser compatibility.

This document summarizes the key new features being introduced in ECMAScript 6 (ES6), also known as Harmony. Some of the major additions include block scope with let and const, classes and modules, iterators and generators, arrow functions, and parameter handling improvements with rest/spread. ES6 is designed to be backwards compatible with ES5 while adding new functionality. Many new features are already being implemented in modern browsers and Node.js using flags or alternative syntax like --harmony for testing purposes today.

This document discusses advanced Java debugging using bytecode. It explains that bytecode is the low-level representation of Java programs that is executed by the Java Virtual Machine (JVM). It shows examples of decompiling Java source code to bytecode instructions and evaluating bytecode on a stack. Various bytecode visualization and debugging tools are demonstrated. Key topics like object-oriented aspects of bytecode and the ".class" file format are also covered at a high-level.

Do ever wonder how ECMAScript evolves and it's available almost everywhere? We gonna do a walkthrough of how TC39 (the technical committee responsible for the ECMAScript) works, how to participate, contribute, and how an idea can make it through to the language, all step-by-step. Together with a sneak pick and debate about some recent and interesting proposals in different stages. (c) Fest.js Porto 2023 April 20, 2023 Porto, Portugal https://fest.dev/events/js/porto-2023/

Tamarin is a new virtual machine from Adobe that is well-suited for ActionScript. It will power future versions of JavaScript through projects like ActionMonkey (integrating Tamarin into SpiderMonkey), ScreamingMonkey (bringing Tamarin to Internet Explorer), and IronMonkey (bringing other languages to Tamarin). ECMAScript 4 aims to build upon ECMAScript 3 with features like classes, packages, type annotations, and more to support both large and small programs. The reference implementation of many ECMAScript 4 features are written using ECMAScript itself, allowing the language to be self-hosting.

The rough presentation that I gave at the Ajax Experience, Adobe Max Tokyo, and Mozilla Japan/Shibuya.JS.

This document provides an overview of ECMAScript 6 (ES6), also known as ECMAScript 2015. It discusses the history and standardization of JavaScript and ECMAScript. It then covers many of the new features introduced in ES6, including let and const block scoping, arrow functions, template literals, classes, generators, iterators, promises, and modules. It encourages using ES6 features today via tools like Traceur and Babel that compile ES6 to ES5 for browser compatibility. It also looks ahead to future features planned for ECMAScript 7 and beyond.

JavaScript provides core functionality for web pages and applications. It has a C-like syntax and is dynamically typed. JavaScript code runs on both the client-side in web browsers and the server-side in environments like Node.js. It uses prototype-based inheritance where objects can inherit properties from object prototypes. New features are being added regularly through the ECMAScript specification. JavaScript allows DOM manipulation to modify web pages and event handling for user interactions.

The document discusses several tools for JavaScript development including: 1. ECMAScript 6 for new JavaScript features, Visual Studio Code for editing, and Node.js & npm for modules. 2. Build tools like webpack, Babel, and UglifyJS to bundle, transpile, and minimize code. 3. Testing with Jasmine and debugging with Chrome Developer Tools and source maps. 4. Documentation generation with YUIDoc. A demo project is provided at https://github.com/simonkim/jstools-demo to show how to use these tools together in a workflow.

This document discusses JavaScript libraries and proposes ideas for improving them. It argues that while libraries are useful, developers should understand JavaScript fundamentals first. Current libraries have inconsistent APIs and lack modularity. The document proposes a new "CommonBrowserJS" library with common standards, pure feature detection, and support for CommonJS modules to converge the best ideas from existing libraries. Developing a simple "has.js" library for feature detection could be a first step. Overall the document advocates for improving JavaScript libraries by standardizing APIs and reducing magic while embracing modern JavaScript practices.

Some javascript testing patterns that has made writing tests at Refinery29 more maintainable. Covered in this presentation is userContext (or let) in Jasmine, lazy evaluation and shared behavior.

The document discusses decoupling JavaScript code into modular pieces. It recommends defining shared code as modules that can be extended for different environments like desktop and mobile. Modules should be scalable, maintainable and reusable. The document provides an example of defining a viewport module with shared, desktop and mobile code, and communicating between modules using events instead of direct callbacks. The overall recommendations are to build the next version of Chico using a modular structure with prototype extension and event-based communication between modules.

The document discusses the features and capabilities of HTML5. It covers new semantic elements, forms, offline storage, device access, multimedia, 3D graphics, performance improvements, and CSS3 features. Key points include more meaningful tags, custom data attributes, offline application caching, geolocation, cameras, web sockets, and canvas/WebGL for graphics.

The document discusses JavaScript's prototype property and object-oriented programming. It explains that in JavaScript, objects inherit properties and methods from a prototype object, allowing for code reuse and extension of functionality. The prototype is an object that is shared among objects created from the same constructor function. All objects in JavaScript inherit from the Object prototype by default.

Is your patent a vanity piece of paper for your office wall? Or is it a reliable, defendable, assertable, property right? The difference is often quality. Is your patent simply a transactional cost and a large pile of legal bills for your startup? Or is it a leverageable asset worthy of attracting precious investment dollars, worth its cost in multiples of valuation? The difference is often quality. Is your patent application only good enough to get through the examination process? Or has it been crafted to stand the tests of time and varied audiences if you later need to assert that document against an infringer, find yourself litigating with it in an Article 3 Court at the hands of a judge and jury, God forbid, end up having to defend its validity at the PTAB, or even needing to use it to block pirated imports at the International Trade Commission? The difference is often quality. Quality will be our focus for a good chunk of the remainder of this season. What goes into a quality patent, and where possible, how do you get it without breaking the bank? ** Episode Overview ** In this first episode of our quality series, Kristen Hansen and the panel discuss: ⦿ What do we mean when we say patent quality? ⦿ Why is patent quality important? ⦿ How to balance quality and budget ⦿ The importance of searching, continuations, and draftsperson domain expertise ⦿ Very practical tips, tricks, examples, and Kristen’s Musts for drafting quality applications https://www.aurorapatents.com/patently-strategic-podcast.html
