To copy an array of objects to another array without object reference in JavaScript, we use some JSON methods.
For instance, we write
const tempArray = JSON.parse(JSON.stringify(mainArray));
to call JSON.stringify with mainArray to convert the array to a JSON string.
Then we call JSON.parse with the string to convert it back to an array to make a copy.
This works if mainArray is an array with plain JavaScript objects or primitive values.
