ECMAScript6-tester

Script (and possibly an addon) that tests your website for compatibility with coming ECMAScript-6 features

I plan to add a script that logs usage of new builtins to be included first.

Resources:

• https://wiki.mozilla.org/ES6_plans
• http://kangax.github.io/es5-compat-table/es6/
• http://people.mozilla.org/~jorendorff/es6-draft.html

Aim: Preempt problems like this before the features are implemented.
