Main image of article Python, Swift, JavaScript, Java: Best Ways to Learn Them
Learning a new programming language—or merely staying adept in ones you know already—is a necessary challenge for programmers and developers who want to stay relevant. Fortunately, every popular programming language comes with tons of documentation, as well as a variety of online tutorials. Check out these handy resources: JavaScript ranks high on everybody’s list of the most popular programming languages. Earlier this summer, for example, tech-industry analyst firm RedMonk drew publicly available data from GitHub and Stack Overflow that suggested programmers and developers use JavaScript more than other trendy languages, including PHP and Python. Thanks to its popularity, resources for learning JavaScript are widely available: There’s a very solid guide on the Mozilla Developer Network, for example, as well as some tutorials on learn.jQuery.com.

Java/J2EE is popular with tech pros, according to a recent survey by Dice, who use it to build everything from open-source productivity software to websites and databases. Those who want to explore more about Java can head over to an Oracle-hosted site with a variety of tutorials. C#, a popular language created by Microsoft as part of its .NET initiative around 15 years ago, bears many similarities to Java. Developers have worked diligently to integrate new features into the language, and today it provides everything from automatic garbage collection to strong type checking. If you want to learn more about it, Microsoft’s Visual Studio website offers everything from C# tutorials and resources to programming concepts. Python placed number-one on a recent list of the most popular programming languages taught in college-level introductory computer-science classes, and given its ubiquity—everyone from independent developers to tech titans such as Google seem to use it—that placement seems more than justified. Students (and anyone else interested) can head to Python.org for a deep dive into the language’s particulars. Swift is Apple’s new language for building iOS apps, and on that basis alone, tech pros expect that it’ll become enormously popular over the next few years. Although Apple itself has long maintained an air of strict secrecy regarding its products and internal processes, it’s been uncharacteristically open with Swift, even launching a new blog detailing the language’s evolution. For those who want to begin working with it, Apple also offers a lengthy guide in e-book form, via iTunes.
