- `Array.map` becomes `Array.from`
- Array copying via `Array.slice` becomes `Array.from`.
- `Array.forEach` that did not rely on closures becomes `for`-`of` loops.
- Anything else: `Array.X` becomes `Array.prototype.X`.
Complex cases:
dom/bindings/test/TestInterfaceJS.js and
dom/bindings/test/test_exception_options_from_jsimplemented.html
use `Array.indexOf` to generate an error with a specific error message.
Switched to `Array.prototype.forEach` to generate the same error.
js/src/jit-test/tests/basic/exception-column-number.js
In this test `Array.indexOf()` is used to generate an error. Since the
exact message doesn't matter, I switched to `Array.from()`.
Intentionally not changed:
editor/libeditor/tests/browserscope/lib/richtext/richtext/js/range.js
Did not modify because this is 3rd-party code and the code uses
feature detection as a fall back when Array generics are not used.
testing/talos/talos/tests/dromaeo/lib/mootools.js
Did not modify because mootools adds the `Array.slice` method to the
`Array` object.
Not changed because they check the implementation of Array generics:
