Please consider updating this to mention the optional chaining operator, ?.,. Browser support isn't at the point where I'd use it for general code, but it's heading in that direction. In addition, there's now the nullish coalescing operator (??), with a similar status.

Am I going bananas? Surely the objection of user2451227 (currently with 4 votes) is invalid because the ternary's middle operand (i.e. right operand with the Elvis operator) would equally not be picked if the expression/left operand is defined and falsy. In both cases you then have to go x === undefined.

Adds missing word from first sentence.

| Oct 4, 2016 at 17:25 | comment | added | jinglesthula | While this answers the question it is almost entirely about coffeescript rather than javascript, and is more than half about describing coffeescript benefits unrelated to the OP. I'd suggest boiling it down to just what's relevant to the question, as wonderful as coffeescript's other benefits are. | |

The CoffeeScript home page uses <script type="text/coffeescript">.

Another very minor fix.

Is it my mistake, or it is really <script type='coffee/script>'?
