Minimal polyfills for modern browser applications
This polyfill contains the following polyfills:
PromisefetchMapSetArray.findArray.findIndexArray.fromObject.valuesObject.assignrequestAnimationFrame(rAF)
Just import it at the beginning of your application and go wild.
import 'browser-polyfills';Note that this package will only polyfill what your browser environment does not
have. For example, if the user's browser has fetch, this package will not add
the polyfill and your application will keep using the browser's native code.
This package fine-tunes some aspects of the polyfilled packages. Note that the
enhancements described here are done in spite of the browser's support (i.e.
if fetch is supported by the browser, the enhancement will still be applied).
Both native and polyfilled fetch functions have a major inconsistency related
to the function's outcome. Basically fetch can either return a Promise when
successfully communicates with the server, or throws an error when it cannot.
This inconsistency can easily lead to repeated or bloated code and/or unhandled
errors. This package prevents this inconsistency and forces fetch to always
return a Promise. I.e. instead of throwing an error, fetch will return a
rejected Promise, to be handled like any Promise would - with a catch.
