Actually JavaScript and Java are really much not related. Java is definitely an complex programming language while JavaScript is only the server scripting language. The syntax involving JavaScript is mainly inspired by the encoding language Chemical.

Being some sort of scripting dialect, JavaScript simply cannot run on its own. Found in fact, the browser accounts for running JavaScript code.
