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.

Factor #2: The long term prospects

Java is mentioned in more job postings than any other programming language. JavaScript is a close second.But here’s the thing about JavaScript: even though it’s been around for 20 years, it only recently became a serious tool that companies like Netflix, Walmart, and PayPal would build entire applications around.As a result, plenty of companies are hiring JavaScript developers, but there just aren’t that many on the job market.

Factor #1: The job market

Most programmers would agree that high-level scripting languages are relatively easy to learn. JavaScript falls into this category, along with Python and Ruby.

Factor #3: Difficulty to learn

<h1>Learn one language well. Then learn a second one.</h1>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:<ul><li>C is a great way to learn how computers actually work in terms of memory management, and is useful in high-performance computing</li><li>C++ is great for game development.</li><li>Python is awesome for science and statistics.</li><li>Java is important if you want to work at large tech companies.</li></ul>

Learn one language well. Then learn a second one.

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:<blockquote>“Any application that can be written in JavaScript, will eventually be written in JavaScript.”</blockquote>

Factor #4: Projects you can build with it

Many universities still treat programming like it’s computer science, and computer science like it’s math.As a result, many introductory programming courses focus on low-level-of-abstraction languages like C, or mathematically-focused languages like MATLAB.
