According to this page http://kangax.github.io/compat-table/es6/, ES6 features are not implemented in IE 11.
Does IE 11 have a plan for implementing them one day or can I forget about it? Is there a page that explain their intent on that subject?
I read somewhere (I cannot remember where exactly) that they don't plan to fix bugs in IE 11, so my guess is that they won't bother implement new features?
