Slicing Arrays in JavaScript: Basic Usage The extracted elements (2 and 3) are returned in a new array, which is then logged to the console. In this example, the slice() method is used to extract elements from the myArray array starting at index 1 (which is the second element) and ending at index 3 (which is the fourth element). Here's an example of how to use the slice() method: const myArray = It's important to note that the slice() method does not modify the original array instead, it returns a new array containing the extracted elements. If the endIndex parameter is not specified, the slice() method will slice to the end of the array. The endIndex parameter specifies the index of the first element to exclude from the new array. If the startIndex parameter is not specified, the slice() method will start at index 0. The startIndex parameter specifies the index of the first element to include in the new array. The slice() method takes two parameters: startIndex and endIndex. The syntax of the slice() method is as follows: array.slice(startIndex, endIndex) The slice() method is a built-in method in JavaScript that allows you to extract a section of an array and return a new array containing the extracted elements.
