![]() In javascript, there is a method known as the slice() method. The `slice` method does not modify the original array but returns a new one with extracted elements. An array slice is a method of slicing the given array to obtain part of the array as a new array. It takes two parameters: the starting index and the ending index, with both being inclusive or exclusive depending on how it’s used. The `slice` method in JavaScript is a useful tool for extracting sections of an array into a new array. Note that the `slice` method does not modify the original array, but returns a new array with the extracted elements. The array can be created with the array directly by using the new keyword as shown below in the syntax. In `slice3`, we extract the last two elements of the array. In `slice2`, we extract all the elements from index 2 (inclusive) to the end of the array. This method doesnt change the original array. In `slice1`, we extract the elements between index 1 (inclusive) and index 3 (exclusive), which are `’banana’` and `’orange’`. The JavaScript array slice() method extracts the part of the given array and returns it. We then use the `slice` method to extract a section of the array into a new array. ![]() In this example, we have an array called `fruits`. The start index is inclusive, while the end index is exclusive. ![]() It takes two arguments: the start index and the end index (optional). It takes two parameters: the starting index and the ending index.Ĭonst fruits = Ĭonst slice1 = fruits.slice(1, 3) // Ĭonst slice2 = fruits.slice(2) // Ĭonst slice3 = fruits.slice(-2) // The slice() method in JavaScript is used to extract a portion of an array or a substring from a string without modifying the original array or string. ![]() You can use the `slice` method in JavaScript to extract a section of an array into a new array. We’ll look at examples and explain what parameters are needed, as well as how it works without modifying the original array. This blog post will discuss how to use the `slice` method in JavaScript to extract a section of an array into a new array. ![]()
