What is JavaScript?

  • JavaScript is a dynamic, weakly typed programming language which is compiled at runtime. It can be executed as part of a webpage in a browser or directly on any machine ("host environment")
  • JavaScript was created to make webpages more dynamic (e.g. change content on a page directly from inside the browser). Originally, it was called LiveScript but due to the popularity of Java, it was renamed to JavaScript.
  • JavaScript is totally independent from Java and has nothing in common with Java!
