About Javascript

Javascript is the only language that runs directly in the browser. It was originally created for running small scripts and visual effects in the browser, but then people realized they could create full applications with it, and the modern web app was born. Some web apps depend completely on javascript and others are just very limited without it (for example, try running Gmail without javascript).

Javascript has some quirks, but it has become extremely popular due to its unique ability to run in browsers, combined with its power and flexibility. In the last few years, developers have been using it other areas, such as browser extensions, web servers, smartphone apps, and desktop programs.
