Prefer use of an object spread over Object.assign.
//Bad:
Object.assign({}, foo)
Object.assign({}, {foo: 'bar'})
Object.assign({ foo: 'bar'}, baz)
Object.assign({ foo: 'bar' }, Object.assign({ bar: 'foo' }))
Object.assign({}, { foo, bar, baz })
Object.assign({}, { ...baz })
// Object.assign with a single argument that is an object literal
Object.assign({});
Object.assign({ foo: bar });
//Good:
Object.assign(...foo);
// Any Object.assign call without an object literal as the first argument
Object.assign(foo, { bar: baz });
Object.assign(foo, Object.assign(bar));
Object.assign(foo, { bar, baz })
Object.assign(foo, { ...baz });
