Changes include:
*
Removed ‘new super()’ syntax
*
new.target meta-property no longer highlighted as tentative.
*
Methods defined within class definitions are now non-enumerable
*
Classes defined as class extends null {...} are now consider to be
derived classes
*
Constructors defined using class definition syntax throw when
called as functions
*
Function.prototype.toMethod has gone away. Only class declarations
and object literals can set a functions [[&&HomeObject]]
I prefer to think of toMethod as "deferred", not "gone away" (taken to
mean "for good" sometimes). ;-)
*
Object.prototype.toSring no longer censors use of legacy %%lass
<http://wiki.ecmascript.org/doku.php?id=harmony:lass> values.
Yay!
*
Empty object destructuring patterns without default values (eg, {
}) throw if the value assigned to them is null or undefined. This
make { } more consistent with the behavior of [ ]
*
Array destructoring performs an InteratorClose upon iterators it
creates.
*
Fixed handling of throw and close methods received by a yield*
(see bug https://bugs.ecmascript.org/show_bug.cgi?id=3526 )
(further refinements may still be coming).
s/close methods/return methods/
I like calling it `close` still, too :-P. My inner Pythonista talking.
*
IteratorClose no longer cares whether the object returned from the
‘return’ method has done:true.
