Typescript slice4/26/2023 ![]() ![]() The original way to handle this was to use the call() method to run the () method on your NodeList, like this. So… how do you convert a NodeList to an array? ( MDN provides an example using Python with getElementsByTagName().) Converting a NodeList to an Array As of version 0.51, Slice Machine can generate TypeScript types for your Slices and Custom Types automatically thanks to prismic-ts-codegen. Turns out, other languages can access these methods, too. The splice () method returns the removed item (s) in an array and slice () method returns the selected element (s) in an array, as a new array object. 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.

If you wanted a slice of length 2 from a given position, you would do: var a 100, 200, 300, 400 var pos a.indexOf (200) a. ![]() NodeLists and Arrays are two different things because NodeLists are actually not a JavaScript API, but a browser API.

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 ![]()
