Notes

As ES6 refers to a huge specification and browsers have various levels of support, "Supported" means at least 95% of the spec is supported. "Partial support" refers to at least 10% of the spec being supported. For full details see the Kangax ES6 support table.

Notable partial support in IE11 includes (at least some) support for const, let, block-level function declaration, typed arrays, Map, Set and WeakMap.
Does not support tail call optimization
Only has partial Symbol support and partial support for RegExp.prototype properties
