Noticed Rollup was complaining about
_extends
helper repeating.But we don’t need it. Instead let’s emit
Object.assign
calls.Diff of build folder: https://gist.github.com/gaearon/50e2b020a6d7d549e2c7b0273f01016e.
FB and RN bundles now get plain
Object.assign()
, UMD and CJS bundles keep using the polyfill.
