What's causing this sluggish performance?

I'm in the process of developing a Google Chrome extension and I can't help but wonder why

window.onload = loadPage;
function loadPage() {
    document.getElementById('nav-robux-amount').innerHTML = '0';
    console.log("Robux have been successfully hidden.");
}

it's performing so slowly, and if there's a faster alternative available.

Answer №1

It is indeed true that by using window.onload, your function will only be called once the entire page has finished loading. If you want your function to execute without waiting for all elements to load, you can consider using DOMContentLoaded instead.

The DOMContentLoaded event triggers when the main HTML document has been completely loaded and parsed, disregarding the need for stylesheets, images, and subframes to finish loading.

window.addEventListener('DOMContentLoaded', (event) => {
    console.log('DOM fully loaded and parsed');
});
