Background
JavaScript is a lightweight, interpreted programming language with object-oriented capabilities that allows you to build interactivity into otherwise static HTML pages. The general-purpose core of the language has been embedded in Netscape, Internet Explorer, and other web browsers.
JavaScript was created by Brendan Eich in 1995 to give web pages a little more pep than the <blink> tag could provide. Today it has far more powerful uses and companies like Google and Facebook use JavaScript to build complex, desktop-like web applications. With the launch of Node.js, It has also become one of the most popular languages for building server-side software. Today, even the web isn’t big enough to contain JavaScript’s versatility. I believe that you are already aware of these facts and this has made you land on this JavaScript Interview Questions article.
So, if you are planning to start your career in JavaScript and you wish to know the skills related to it, now is the right time to dive in, when the technology is in its blossoming state. JavaScript Interview Questions will provide you with in-depth knowledge and help you prepare for your interviews.

The numbers speak for themselves. According to the US Bureau of Labor Statistics, web developer jobs are targeted to grow by 40% in 2012-2022, which is much higher than any other stream.

So, if you’re getting interviewed for any kind of web development position, or for Android / iPhone app developer positions, you’ve got to brush up your JavaScript skills.
