How to copy array by value with JavaScript?

Spread the love

To copy array by value with JavaScript, we use the slice method.

For instance, we write

const oldArray = [1, 2, 3, 4, 5];
const newArray = oldArray.slice();

to call oldArray.slice with no arguments to make a copy of oldArray and return it.
