Benchmark: Manually join two objects vs Object.assign.

Script Preparation code:

base = {
	asdsA: 'dasdsa',
	dsad: 434534,
	hji: 'asdsa',
};

second = {
	thing: 'hey'
};

createCopy = (base, other) => {
	return {
  	asdsA: base.asdsA,
    dsad: base.dsad,
    hji: base.hji,
    thing: other.thing,
  };
};

Tests:

Simple Assign
Object.assign({}, base)
Assign joining 2 objects
Object.assign({}, base, second);
Manually joining 2 objects
createCopy(base, second);
