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. The original way to handle this was to use the call() method to run the () method on your NodeList, like this.JavaScript is the language that is used to make the website dynamic and more interactive. So… how do you convert a NodeList to an array? ( MDN provides an example using Python with getElementsByTagName().) Converting a NodeList to an Array Turns out, other languages can access these methods, too. This used to confuse me like crazy, too, because JavaScript is the scripting language of the front end. You can then manipulate them with JavaScript. Things like querySelectorAll() and getElementsByTagName() aren’t JavaScript methods, they’re browser APIs that let you access DOM elements. NodeLists and Arrays are two different things because NodeLists are actually not a JavaScript API, but a browser API. What’s the difference between a NodeList and an array anyways? I actually wrote about this last year. Today, I’m going to show you how to convert a NodeList to an array so you can take full advantage of all those cool new ES6 array methods. Unfortunately, you can’t use any of these with the elements you get back when using querySelectorAll(), because it returns a NodeList, not an array. The native JavaScript ES6 release brought a handful of helpful methods for working with arrays: Array.forEach(), Array.every(), Array.some(), Array.filter(), and more. Converting a NodeList to an array with vanilla JavaScript
