JS: Does Object.assign() create deep copy or shallow copy

Question

I just came across this concept of

var copy = Object.assign({}, originalObject);

which creates a copy of original object into the \"

Answer 1

By using Object.assign(), you are actually doing Shallow Copy of your object. Whenever we do an operation like assigning one object to other, we actually perform a shallow copy, i.e. if OBJ1 is an object, modifying it through another object which is OBJ2 will reflect changes in OBJ1 too.
