@putout/plugin-convert-object-assign-to-merge-spread

The Object.assign() method copies all enumerable own properties from one or more source objects to a target object and returns the modified target object.

Spread syntax (...) allows an object expression to be expanded in places where zero or more key-value pairs are expected.

(c) MDN

????Putout plugin adds ability to convert Object.assign() to merge spread since it shorter but does (mostly) the same. Merged with @putout/plugin-spread.
