Transforming jQuery to Vanilla JavaScript: A Simple Guide

In the world of web development, jQuery has been a popular tool for interacting with the DOM (Document Object Model). However, many developers are transitioning towards using Vanilla JavaScript to reduce dependency on libraries. If you find yourself wondering how to translate jQuery code into pure JavaScript, you're not alone!

The Problem

Here's a specific jQuery snippet that many developers might want to convert to Vanilla JavaScript:

The challenge arises when trying to directly interact with classes and event handling in Vanilla JavaScript. For instance, using getElementByClassName for event triggers may not work as intuitively as jQuery. But don't worry! Let's break down the solution step-by-step.

Understanding the Solution

Here’s how we can achieve the same functionality written in Vanilla JavaScript:

The Code

The converted Vanilla JavaScript code looks like this:

Breaking It Down

Selecting Elements:

jQuery: $('.flip-button') selects all elements with the class flip-button.

Iterating Over Elements:

jQuery: The each(function() method loops through each selected element.

Vanilla JS: We use forEach(element => { ... }) to iterate over the NodeList returned by querySelectorAll.

Adding Events:

jQuery: $(this).click(function() { ... }) assigns a click event to the current element in the loop.

Toggling Classes:

jQuery: $(this).closest('.flip-card-inners').toggleClass('flip-card-active') finds the closest ancestor with that class and toggles it.

Final Thoughts

Translating jQuery code to Vanilla JavaScript may seem daunting at first, especially when it comes to unfamiliar methods and properties. However, understanding the concepts of DOM manipulation and event handling can clear up any confusion. The transition allows developers to create more lightweight applications without needing to depend on libraries.

Now you have a clear template to follow for converting any jQuery code into Vanilla JavaScript, empowering you to write cleaner and more efficient code. Happy coding!
