Categorized request examples and articles tagged with [javascript-clone-array] keyword How do I clone a JavaScript array?
You can clone a JavaScript array using the Object.assign() and array.forEach() methods, a for loop, or a spread operator (the fastest way). The Object.assign() method creates a shallow array copy of all enumerable properties from one or more source objects. The spread operator ("...") is handy and fast but has been available since ECMAScript 6 and can be used to clone JavaScript arrays by expanding them. This spread operator clones multidimensional JavaScript arrays by reference, not by value. In this JavaScript Array Cloning Example, we use the spread ("...") operator to clone an array.
