Script Preparation code:

arr = [];
for (let i = 0; i < 200; i += 1) {
    arr.push({
      name: `Person${i}`,
      birthday: moment().add(i, 'days').toDate(),
    });
  }

Tests:

Lodash cloneDeep
const cloneArr = _.cloneDeep(arr);
Deep clone with JSON.parse(JSON.stringify(obj))
const cloneArr = JSON.parse(JSON.stringify(arr));
