eslint-plugin-prefer-spread

Suggest using the spread operator over Object.assign.

Warns for the following (when the first argument is any object literal):

// copies own enumerable properties
Object.assign({}, foo /* ... */);
_.assign({}, foo /* ... */);

Also warns for the following (with the "includeNearEquivalents" option):

// copies own and inherited enumerable properties
$.extend({}, foo /* ... */);
_.assignIn({}, foo /* ... */);
_.extend({}, foo /* ... */);

Does not warn:

// deep copy
$.extend(true, {}, foo);
