How do I slice a JavaScript array?

To slice an array in JavaScript, you can use the array.slice(start, end) method, which returns a shallow copy of the original array containing the selected elements from the original array. The slice() method accepts two optional parameters. The first parameter specifies the starting index from which the elements will be retrieved. If the first parameter is not specified, the method assumes the default value for "start" is "0". The second parameter is the index up to which the elements should be retrieved. If the second parameter is not specified, then the array will be retrieved up to the end of the array. If the end value is greater than the length of the array, then the end value will be equal to the array's length. If the parameters "start" and "end" are negative numbers, then the elements are selected from the end of the array. The array.slice() method does not change the original array. In this JavaScript Slice Array Example, we use the slice() method. Click Execute to run the JavaScript Array Slice Example online and see the result.
