Your definitions of shallow and deep copy are incorrect. What you call a reference is actually a shallow copy (and a reference), while the Object.assign() is a partial deep copy :)

Hi, for a normal object you don't think it is better to use the spreed operator {...obj} than Object.assign({}, obj), this for both readability and performance. ;)
