Javascript is a programming language that helps you create interactive web pages. When you visit a website, your web browser (Google Chrome, Yahoo, Bing, or Mozilla Firefox) downloads the HTML file for that page. The HTML file contains instructions for the browser on how to display the page.
For example, some interactive features of JavaScript include creating forms, validating form input, detecting when a user clicks on a button, and much more.
JavaScript is one of the three main languages used to create web pages. The other two are HTML and CSS. HTML is used to structure the content of a web page, whereas, CSS is used to add style to the page (colors, fonts, etc.) You can think of the three languages as a complete body, broken down, HTML is the skeleton of a web page, CSS is the skin, and, JavaScript adds muscle to the page by making it interactive.
Overall Javascript is a valuable program that helps make your website more functional and usable, try utilizing Javascript on your website in support of your web design and consumer needs.
