Since both this and my parent post on JavaScript being compiled were downvoted without comment I can only make the assumption this is because someone came along who believes this is not the case. So first I will link out to this StackExchange doc that does a pretty good job of describing this. http://programmers.stackexchange.com/questions/138521/is-javascript-interpreted-by-design http://programmers.stackexchange.com/questions/138521/is-jav... The JavaScript specification says nothing about the language being interpreted or compiled. Today; most current versions of major browsers use a just in time compiler to handle JavaScript. V8 (Chrome & Nodejs), SpiderMonkey (Firefox), Chakra (InternetExplorer), Carakan (Opera), JavaScriptCore(Webkit/Safari) For more information take a look at the Wiki entry for EcmaScript engines. https://en.wikipedia.org/wiki/List_of_ECMAScript_engines https://en.wikipedia.org/wiki/List_of_ECMAScript_engines
