About JavaScript

JavaScript is a scripting language that enables us to add functionality to web pages. We can combine JavaScript with our HTML code to achieve this outcome. We typically enclose our JavaScript inside <script> tags, but we can also use event handlers (such as onclick, onchange, onmouseover etc) within the HTML tags themselves to trigger the JavaScript.
