Question

I am trying to run this code in js but it keeps on bringing this error "'$' is not defined". Is it by any chance linked to jquery? if yes what should i do Actually am working in react js but i decided to make this particular page using simple html css and js so it's a little confusing for me

Here is my code

js file

$('.nav ul li').click (function(){
    $(this).addClick("active").siblings().removeClass('active')
})

You are trying to use jQuery in your javascript and you haven't imported it yet. $ is the alias for jQuery.

Put this line before your script file.

<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script>
