Javascript is used primarily by Web browsers such as Chrome, Firefox, Opera, etc. to create dynamic and interactive web pages for its client. Most of the functions and applications that make the Internet indispensable to modern life are coded in some form of JavaScript.

The earliest incarnations of JavaScript were developed in the late 1990s for the Netscape Navigator Web browser. At the time, Web pages were static, offering little user interaction beyond clicking links and loading new pages. For the first time, JavaScript enabled animation, adaptive content and form validation on the page.

For many years, JavaScript only functioned on a limited number of browsers. Microsoft's Internet Explorer, the largest browser base, did not support JavaScript until much later. Instead, Microsoft created its own proprietary client-side script called JScript. In the early days of Web development, programmers who wished to create dynamic websites were often forced to choose one browser family over the other. This was less than ideal because it made the Internet less universally accessible. JavaScript did not become standardized and widely adopted until 1999. Even after standardization, browser compatibility remained an issue for over a decade.

How does JavaScipt work?
JavaScript is what is known as a client-side script. Most Web applications, such as a search engine, work because of an interaction between the user's device (e.g. computer, phone or tablet) and a remote server. The software on the remote server sends information to the client (i.e. the user's machine) and the software on the client side reads the information and renders a Web page on screen. A client-side script is a programming language that performs its tasks entirely on the client's machine and does not need to interact with the server to function. For instance, if you have a Web page loaded on your computer and your Internet service provider goes down, you are still able to interact with the Web pages already loaded on your browser. You will not, however, be able to navigate to new Web pages or access any data located remotely.
