Answer 1

You can attach js to html in two ways

1. Internal js
</body>
<script>
//js code here
</script>
</html>

2. External js

my a js file with extension js and write your js code in it.

to attach it to html you can use

<link src="myfile.js"> in head tag .

***
In sololearn js section is already attached to html so no need of that here.

Answer 2

To link a Js file with your HTML, you only have to add the source of the script inside the body tag or outside; it doesn't matter. If you are working with libraries, like jQuery, you can add the URL of the library in the source.
