Create a function to execute when the page loads

If you’re looking for an easy way to execute your JavaScript code when the page loads, then look no further. Using jQuery’s onLoad() function is a simple and straight-forward technique that will allow you to get more out of your website or web app.

By using this technique, you can create dynamic pages with complex interactions without having to worry about loading scripts at the right time. This tutorial shows how it works in detail!

Include an onload event handler for your JavaScript code

Let’s take a look at some really cool things you can do with JavaScript onload event handlers!

Add a console message to help debug and test the code 

“You’re building a new program. You want to keep track of how it’s working, but you don’t know what messages to send into the console.”  

This is where debug messages are helpful! They can tell you when something goes wrong or if your code was successful. In this blog post, we’ll show you how to use them in Node.js and React Native apps.

Use JQuery if you want to avoid using document ready and window load events 

One of the most common problems with JavaScript is that sometimes it’s hard to know if it has loaded or not. If you are using document ready or window load events, this can make your code difficult to troubleshoot and debug.

JQuery solves this problem by providing a way for your scripts to run as soon as possible on page load without having an event listener on either document ready or window load.

This means you don’t have to worry about potential errors due to timing issues when loading some scripts before others, which can be rather time consuming if you’re dealing with more than one script file.

It also improves performance because the browser doesn’t have to wait for all of the files necessary for running your script any longer then necessary.

Add more information about how this is done with external libraries like jQuery or Mootools

JavaScript has been around for a while now and is an essential language to know if you’re building anything on the web. It’s super powerful and there are many libraries out there that make it even easier to use, like jQuery.

In this blog post we’ll go over how you can use one of the most popular JavaScript libraries: jQuery, in your React app.
