This is different from passing undefined, which is converted to 0.Īn integer indicating the number of elements in the array to remove from start. If start is omitted (and splice() is called with no arguments), nothing is deleted.Negative index counts back from the end of the array - if start = array.length, no element will be deleted, but the method will behave as an adding function, adding as many elements as provided.Zero-based index at which to start changing the array, converted to an integer. Object.prototype._lookupSetter_() Deprecated.Object.prototype._defineSetter_() Deprecated.Object.prototype._defineGetter_() Deprecated.Use Option + ⌘ + C keyboard shortcut keys in Safari (if the developer menu does not appear, open Preferences by pressing ⌘ +, and in the Advanced tab, check “Show Develop menu in menu bar”).Use CTRL + SHIFT + K keyboard shortcut keys for Mozilla.Use the F12 key in Chrome and other chromium-based browsers.Note: We will use the browser console to demonstrate examples performed in this post. Let’s try to slice a couple of arrays to understand the slice() function better. The last element of the given range of the indices is not included in the resulting array.The slice() method does not affect the original array and returns a new sliced array.The syntax of writing a slice() function is given below:ĪrrayName.slice(startingIndex, endingIndex) The slice method takes two arguments as a parameter and provides the sliced array. The slice() method is used to get some specific elements of an array from a given starting index to the given ending index.
In this post, we learn about a well-known array’s function, “ slice().” What is the slice() method in JavaScript Developers often need to filter out the array, merge multiple arrays, and push or pop elements from an array to fulfill the required tasks. In any programming language, arrays play an important role in storing data and managing different types of data. JavaScript is the language that is used to make the website dynamic and more interactive.
