To copy an array in JavaScript, you can use the built-in array.slice(), array.concat(), array.from(), array.map() methods, or the spread ("...") operator. These methods create a shallow copy of the array. To deep copy an array, you can use the new built-in structuredClone() method or sequentially convert an array to JSON using JSON.stringify() and back using JSON.parse(). When cloning an array, the original array remains unchanged. In this JavaScript Copy Array example, we use the spread operator ("...") to copy an array.
