incorrect flagging ecma-intrinsics: updated whitelist.js

[neha-naazneen]

The rule Validate-JavaScript-APIs(ecma-intrinsics) for JavaScript incorrectly flags couple of intrinsic methods, when they do appear to be part of the ecma specification(https://tc39.es/ecma262/). Upon scrutinizing I found that the whitelist.js used in the implementation(ecma-intrinsics.js) isn't updated. I've updated the whitelist.js.

According to documentation, Aura only supports ES5 syntax + ES6 Promises which means these functions are not recognized in such context.

A lot of purposed modifications were added in ES6 or later, thus not supported in Aura context.

Have you tested all added functions ? Aura code is compiled with Babel if I am correct which means some unrecognized code might fail the compilation.

Hi @Bartheleway,
Thank you for your comment. Neha has added all the newly supported functions but testing for all of them is not done. We will review it and respond to your comment within this week.

Thanks,
