babel-plugin-transform-object-assign
Replace
Object.assignwith an inline helper. If you are authoring an application, rather than a library, it is recommended that you use theObject.assignpolyfill instead.
Example
In
Object.assign(a, b);
Out
var _extends = ...;
_extends(a, b);
Caveats

Will only work with code of the form
Object.assignorObject['assign']. The following patterns are not supported:var { assign } = Object; var assign = Object.assign;
