Technology is fast evolving and companies are switching to programming languages that will help them stay progressive and innovative. Which programming languages are most in-demand among employers? The answer to that question can help you figure out what to learn next on your programming journey. You can also join the Programming or JavaScript sections on Gist.am to chat and ask technology related questions
SQL
Over the past several years, organizations everywhere have awakened to the critical importance of analyzing data for insights. And considering that SQL is the programming language for managing and querying relational databases, it’s the foundation of many organizations’ all-important data operations. If you’re interested in becoming a data scientist, SQL Developer or data analyst, you must learn SQL.
Python
Python is regularly utilized by millions of developers all over the world for a wide variety of purposes. SlashData estimates the Python community at 11.3 million users, and it’s growing thanks to the language’s increased use in some highly specialized fields: “The rise of data science and machine learning (ML) is a clear factor in Python’s popularity.”
If you want to learn the language, start at Python.org, where you’ll find a very handy beginner’s guide. If you’re a visual learner, Microsoft’s video series, “Python for Beginners,” features dozens of short lessons (most under five minutes in length; none longer than 13 minutes) in the various aspects of Python. As with any other language, if you have Python-related questions, don’t be afraid to swing by Stack Overflow to ask experts.
Java
Recently updated to Java 17 (with “thousands” of performance, stability, and security upgrades, reportedly), Java famously powers the backend of numerous projects, from Android apps to Big Data analytics. If you want to start learning Java, check out this list of handy tutorials. Also, keep an eye on Java’s Twitter account, which offers the latest updates.
I believe JavaScript can be argued to be the most powerful programming language today. Easy to learn and abundant of resources online. JavaScript can also be a better way to learn the basics of programming and data structures. When it comes to web development, JavaScript is the engine that powers the web. If you’re interested in working with the language, keep in mind that its front- and back-end frameworks and libraries are just as important to learn.
Just starting out with JavaScript? JavaScript.info offers an extensive walkthrough of fundamentals, including the ever-popular “Hello, world!” It’s also worth reviewing hackr.io (which lists a variety of courses and tutorials for various languages), and Mozilla’s site features a very nice rundown of the language’s basics.
Microsoft C#
When it comes to developing within the Microsoft ecosystem, C# is definitely the most popular Microsoft development language out there. Microsoft C# can be used in conjunction with .NET to build applications for Windows and other platforms, which makes it key to many organizations, particularly Microsoft-heavy ones. Microsoft offers some handy tutorials.
C++
One of the most famous “generalist” programming languages, C++ is 37 years old, and remains in use among many organizations despite the rise of more user-friendly languages. If you’re interested in learning C++, there are free tutorials and documentation online, including a comprehensive one available via w3schools. Hackr.io also has a list of online courses.
TypeScript
This is one of my favorite JavaScript language out there. TypeScript is a superset of JavaScript, meaning whatever you code in it is trans piled to JavaScript. That’s led to some highly entertaining arguments online over whether TypeScript is technically a “full” programming language. One thing’s for certain, though: Many developers find TypeScript useful when working with any kind of JavaScript codebase. Check out typescriptlang.org for all of your documentation and tutorial needs.
Swift
When Apple rolled out Swift in 2014, it positioned the language as a replacement for Objective-C, the programming language that powered the Apple ecosystem for decades. Although Objective-C has managed to hang on (no doubt due to a massive legacy codebase), Swift has also gained in popularity and new features.
If you’re new to Swift, it’s helpful to learn arrays, sets, strings, structs and classes, functions, and more. Swift Playgrounds is a good place to start for many budding technologists, as it attempts to make learning the language into a fun, interactive activity. Swift.org offers the latest updates.
