About
JavaScript is an interpreted, cross-platform, event-driven, object-oriented prorgamming language most commonly used to create interactivity on web pages. It should not be confused with Java, which is a differnet programming language. JavaScript was created by Netscape in 1995, while Java was created by Sun Microsystems in 1995.
Along with HTML and CSS, JavaScript is one of the three core technologies used for web development. The majority of web sites use it and it is understood (run by) all major modern web brwosers. There are both client-side and server-side implementations of JavaScript.
Client-Side JavaScript (CSJS) can be coded in any text editor and run in any modern web browser. CSJS can be run inside a .html or stored seperately in a .js file for modularity purposes. The terms Vanilla JavaScript and Vanilla JS refer to JavaScript not extended by any frameworks or additional libraries. Scripts written in Vanilla JS are plain JavaScript code.
JavaScript was influenced by programming languages such as Self and Scheme and later when on to influence CoffeeScript, Dart, JScript, ActionScript, and TypeScript.
