Let's say we have an element:
<button class="primary active">Click me</button>
And we want to check if the element has the active
class.
Here's how to do this in two simple steps.
const button = document.querySelector('button');
element.classList.contains
method to check for a class:// returns 'true' if the class exists, and 'false' if it doesn't.
const isActive = button.classList.contains('active');
It's really as simple as that!
