Javascript Interview Questions




With richer experiences on the web becoming the norm, Javascript has become something that every web developer absolutely must know because it plays a huge part in improving the web experience. In this section, we present some commonly asked Javascript interview questions. In any interview scenario, you could be asked both conceptual Javascript questions and also to produce some working Javascript code that performs a specific task. In this section, we present the questions in order of difficulty so that they can be read as a tutorial.

Javascript is commonly known to run on the browser-side, but now is even being used to write server side applications. And now that JQuery (a Javascript library) has become very popular, programming in Javascript has become somewhat easier for newbies. But we still highly recommend that you know core Javascript because it will dramatically improve your ability to code complex Javascript.
