Programming exercise #11 - Clone object, without copying reference

// So, you have object like this

const obj = {

firstName: "John",

lastName: "Doe"

}

//Please create second object, that have firstName and lastName
// properties from first object.

console.log(myClonedObject) // {firstName: "John", lastName: "Doe"}

// Your goal is copy only properties, not the reference to object.
// so when we change first object like this :

obj.firstName = "Mary"

// output on cloned object should look the same.

console.log(myClonedObject) // {firstName: "John", lastName: "Doe"}

// Please post your answer as codepen, jsbin or link into your github gist.
