The average Javascript project receives twice as many pull requests as the average Java, python, or Ruby project. 

Javascript’s Ecosystem also benefits from a heavy investment of money and engineering talent from companies like Google, Microsoft, Facebook, and Netflix.

Most programmers would agree that high-level scripting languages are relatively easy to learn. 

JavaScript falls into this category, along with Python and Ruby. 

This is where JavaScript really shines. JavaScript runs on any device that has a browser, right there in the browser. You can build basically anything with JavaScript, and share it anywhere.

Because of JavaScript’s ubiquity, Stack Overflow co-founder Jeff Atwood coined his now-famous law:

“Any application that can be written in JavaScript, will eventually be written in JavaScript.”

Learn one language well. Then learn a second one.

In order to move beyond the basics, you need to learn your first language well. Then your second language will be much, much easier.

From there, you can branch out, and become a more well-rounded developer by learning lots of languages:

• C is a great way to learn how computers actually work in terms of memory management, and is useful in high-performance computing
• C++ is great for game development.
• Python is awesome for science and statistics.
• Java is important if you want to work at large tech companies.
