Discussion on: Copying objects in JavaScript

So there is a lodash library which gives cloneDeep() method to perfectly deep copy an object. Below an example attached:

var objects = [{ 'a': 1 }, { 'b': 2 }];
var deep = _.cloneDeep(objects);

You can also visit this page to find more: lodash.com/docs/4.17.15#cloneDeep

Another approach is to use recursion.
make a custom function like one I have used to iterate on each key in object and if that key is also an object then again call the method to copy the keys.
Something like below:

function isObject(obj) {
  let type = typeof obj;
  return type === 'object';
};

function deepCopy(obj) {
  let copiedObj = {};
  for (let key in obj) {
    if (obj.hasOwnkeyerty(key)) {
      if (isObject(obj[key])) {
        copiedObj[key] = deepCopy(obj[key]);
      } else {
        copiedObj[key] = obj[key];
      }
    }
  }
  return copiedObj;
}
