What data structure is used to store HTML elements in TypeScript?

Currently, I am dealing with a typescript variable that holds the outcome of a query on the DOM:

let games = document.getElementsByTagname("game");

My uncertainty lies in identifying the appropriate type for the resulting array. Should I expect an array containing HTMLElements?

// Attempt 1
let games : Array<HTMLElement> = document.getElementsByTagName("game");

// Attempt 2
let games : NodeList<HTMLElement> = document.getElementsByTagName("game");

Answer №1

To solve this issue, it's recommended to utilize the NodeListOf<T>. Here's an example:

const elements: NodeListOf<Element> = document.getElementsByTagName("element");

While you could use type assertions to convert it into an HTMLElement[], doing so may provide inaccurate type details and deceive your development tools.
