$(document).ready equivalent without jQuery

Title: Lighten Up Your Script: A jQuery-free Solution to $(document).ready

📝 Hey there tech enthusiasts! Are you tired of unnecessary dependencies weighing down your script? 💪 If you're using jQuery solely for its $(document).ready functionality and want to lighten things up, you've come to the right place. In this blog post, we'll explore an easy, jQuery-free solution to implement $(document).ready without any extra baggage. 💼✨

The Problem: Shedding Unnecessary Dependencies

So, you have a script that uses $(document).ready, but you don't need any other jQuery features. Good news! You don't have to carry the entire jQuery library just for this small feature. 🎉 It's time to declutter your code and make it more efficient! But how do we replace $(document).ready without jQuery?

The Challenge: Finding an Equivalent Solution

To address this challenge, one might initially think of using window.onload. However, as you rightly pointed out, window.onload fires after all images, frames, and other resources have finished loading. This behavior isn't equivalent to the jQuery function we want to replace.

The Solution: Replicating $(document).ready

To replicate the functionality of $(document).ready, we can utilize the DOMContentLoaded event, which fires when the document's DOM has finished loading. This event behaves similarly to $(document).ready and is supported by all modern browsers. 🌐

Here's a simple solution using native JavaScript:

document.addEventListener("DOMContentLoaded", function() {
    // Your code here
});

By wrapping your code inside this event listener, you ensure that it will execute as soon as the DOM is ready. 🏁

Example Usage: From $(document).ready to DOMContentLoaded

Let's say you have the following jQuery code:

$(document).ready(function() {
    // Code to execute when the DOM is ready
});

To replace it with the jQuery-free solution, you can simply rewrite it as:

document.addEventListener("DOMContentLoaded", function() {
    // Code to execute when the DOM is ready
});

Voila! 🎩 You've successfully swapped out $(document).ready with a lean, mean alternative.

Take It Further: Improve Performance

Additionally, you can maximize performance by placing your script just before the closing tag. This ensures that the entire page, including all elements, has loaded before executing your code. 💨🚀
