Active Links in Menu

I used JavaScript for this, in case someone looks for the same query I was searching and jumps on this thread:

<script>
(function() {
    const links = document.getElementsByTagName('a')
    const currentUrl = location.href
    for (const link of links) {
        if (link.href === currentUrl) {
            link.classList.add('active')
        }
    }
}())
</script>
