Missing polyfills

NOTE: This polyfill provider is only compatible with polyfills that follow the es-shims-api specification. Additionally, those polyfills must live under the @es-shims organization.

This provider fully supports ES2016+, but we are still working on ES5 and ES6 support. You can find the list of missing polyfills at missing-polyfills.md.
