This drops IE 11 support by default. We no longer ship or use a polyfill entrypoint.
Introduces new package, react-app-polyfill
, with entry points for ie9
, ie11
, and jsdom
.
This also goes a step further and polyfills some things previously not polyfilled, i.e.:
-
Symbol
(used byfor...of
) -
Array.from
(used by[...arr]
)
TODO:
-
verify Array.from
is needed to perform array spread and not handled magically by babel somehow -
add docs on IE 11/IE 9 support
