This is useful when you want to create a new array that has the same elements as an existing array, but you want to modify the new array without affecting the original array. Copying an array: You can use slice() to create a new array that is a copy of an existing array.This is useful when you want to work with only a portion of an array and not the entire array. Extracting a subarray: You can use slice() to extract a subarray from an array.The slice() method is useful in a variety of situations. Instead, it returns a new array containing the extracted elements. The slice() method does not modify the original array. If the endIndex is not specified, the slice() method will extract all elements from the startIndex to the end of the array. If the startIndex is not specified, the slice() method will begin extraction from the beginning of the array (i.e., index 0).

Here, array is the array on which the slice() method is being called, startIndex is the index from where the extraction should begin (inclusive), and endIndex is the index at which the extraction should end (exclusive). The syntax for the slice() method: array.slice(startIndex, endIndex)

It takes two arguments: the starting index and the ending index (exclusive) of the section to be extracted. It is one of the many methods available for manipulating arrays in JavaScript. The slice() method in JavaScript is used to extract a section of an array and return a new array containing the extracted elements.
