Answer 1

To copy the values of an array without copying the reference of the array, you can simply do:

let tempArray = [...mainArray];

This is the recommended solution for AirBnb's JS Style Guide: https://github.com/airbnb/javascript#arrays

However, this will not create new referenes for the objects inside the array. To create a new reference for the array and the objects inside, you can do:

JSON.parse(JSON.stringify(mainArray));
