Add the active class to the current or clicked button,
Step-by-step explanation,
This line selects all elements with the class name .btns inside the element that has the id mydiv.
This loops through each button (each element in buttons).

Every represents one button at a time.
This adds a click event listener to each button.

It means: “When this button (Every) is clicked, run the code inside this function.”,
Before activating the clicked button, this loop goes through all buttons and removes the "active" class from them.

So, no button stays active anymore,
Finally, it adds the "active" class only to the button that was clicked.
When you click any button:

All buttons first lose the "active" class.

The clicked button gets "active" added.

So only one button appears “active” at a time — like in a tab bar or option selector.

This code makes sure that only the clicked button gets the "active" class, and all others lose it.
