FACEBOOK and JAVASCRIPT
Practically every company you can think of uses JavaScript. Why?
First, because the web is all-pervasive in our world. We can’t avoid it.
Second, because the web browser (or some kind of web browser component) is the only tool available for using the web.
Third, because JavaScript is the only language that is native to the web browser, so if you’re going to write a web browser application, you have to use JavaScript.
What is JavaScript?
JavaScript is a text-based programming language used both on the client-side and server-side that allows you to make web pages interactive. Where HTML and CSS are languages that give structure and style to web pages, JavaScript gives web pages interactive elements that engage a user. Common examples of JavaScript that you might use every day include the search box on Amazon, a news recap video embedded on The New York Times, or refreshing your Twitter feed.?
Incorporating JavaScript improves the user experience of the web page by converting it from a static page into an interactive one. JavaScript is mainly used for web-based applications and web browsers
