Html is used for writing a webpage, CSS for styling it , but...what is JavaScript used for???? JavaScript controls the pages modification, for example if you get an email you don't have to reload the page. when you opened this post, you may have seen an alert come up. That was JavaScript. JavaScript is surrounded by <script> tags. this is how yu would create a simple alert.
<script>That is how you would write it. JavaScript goes in between the script tags and html tags. We will not be learning anymore JavaScript for a while, as it is not needed for the basic website. Sorry for the short post!!
alert("This is JavaScript");
</script>
