Babel-polyfill Promises and "finally" support

Question

How to enable finally method support if i'm using babel-polyfill in my project build on React-Redux stack

Answer 1

Actually, now it has a proposal, and it's recently got into Stage-3, WebKit already supports it. Spec compliant shim/polyfill libraries are already available too. We can expect an update from the Promise polyfill library maintainers also.

Answer 2

I believe, the Babel-Polyfill shim uses core-js under the hood, which does support Promise.finally: https://github.com/zloirock/core-js#commonjs
