what is queryselectorall().find() equivalent in javascript

querySelectorAll() method returns a Node List of all the matching HTML elements based on a given CSS selector. On the other hand, find() method is used to return the value of the first element in an Array that satisfies a given condition.

To achieve the equivalent functionality of querySelectorAll().find() in JavaScript, we need to convert the Node List obtained from querySelectorAll() to an Array and then call the find() method on the Array.

Here's an example code block that demonstrates the usage of querySelectorAll().find() equivalent in JavaScript:

index.tsx
// select all the divs in the HTML document 
const divs = Array.from(document.querySelectorAll('div'));

// find the first div with class "example" 
const exampleDiv = divs.find(div => div.classList.contains('example'));

In the above example, we first use querySelectorAll() to select all the div elements in the HTML document and convert it to an array using the Array.from() method. Then we use the find() method on this array to find the first div element that has a class of 'example'.
