The slice() method is used to convert an array-like object into an array. ![]() The rgb array contains the first three elements of the colors array. The typical use of the slice() method is to copy a portion of an array without modifying the source array. In this example, the newNumbers array contains all the elements of the numbers array. The slice() is used to clone an array as shown in the following example: In addition, it doesn’t change the source array. It’s important to keep in mind that the slice() method performs the shallow copy of elements to the new array only. The slice() returns a new array that contains the elements of the original array. If you omit the stop parameter, the slice() method will use the length of the array for the stop parameter. It means that the slice() method doesn’t include the element at the stop position in the new array. The slice() method extracts up to stop-1. The stop parameter, as its name implies, is a zero-based index at which to end extraction. If the start is undefined, slice() begins at 0. The start parameter determines the zero-based index at which to start extraction. The slice() method accepts two optional parameters as follows:īoth start and stop parameters are optional. Introduction to JavaScript Array slice() method ![]() In this tutorial, we will show you the practical uses of the JavaScript array slice() method. The Array.prototype object provides the slice() method that allows you to extract subset elements of an array and add them to the new array. 3 Pragmatic Uses of JavaScript Array slice() Method
