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

Other answers are complicated.
Some don't answer the question at all.

Below worked for me

// orignal object with deep keys
var originalObject = {
    k1: "v1",
    k2: "v2",
    deepObj: {
        k3: "v3",
        k4: "v4"
    }
};

// make copies now
var copy1 = JSON.parse(JSON.stringify(originalObject));
var copy2 = JSON.parse(JSON.stringify(originalObject));

Hope that helps.
