I do not know why a JSON way of doing this has not been suggested yet. You can first stringify the object and then parse it again to get a copy of the object.

let uniqueArr = [];
let referencesArr = [];
let obj = {a: 1, b:2};

uniqueArr.push(JSON.parse(JSON.stringify(obj)));
referencesArr.push(obj);

obj.a = 3;
obj.c = 5;
uniqueArr.push(JSON.parse(JSON.stringify(obj)));
referencesArr.push(obj);

//You can see the differences in the console logs
console.log(uniqueArr);
console.log(referencesArr);
