How to choose the best programming language for your career

Aiden Pople

When you’re looking for the next step in your coding career, it's generally a good idea to diversify your skillset, as only working with one language will limit the opportunities open to you. Learning a new programming language can be daunting, so much potential and so many options, how do you know which one to pick? We've put together a guide with five of the most financially rewarding languages and its features, to help find the one that suits you.


Developed by Microsoft in the late ‘90s/early 2000s, C# (pronounced C Sharp) is a combination of the best elements of C and C++. Known for its simplicity and widespread use, it's used to build software applications for Windows, web and mobile. As of July 2018, Microsoft Windows still has an 82.8% market share of desktop operating systems, so applications built in C# are in hot demand.

C# is also the platform for video game engine Unity. More than a third of top games are built using this engine and it has a massive part to play in the future of technology with 90% of Samsung's VR Software built in Unity. C# is a great choice for any programmer hoping to break into the game development and virtual reality industry or for building applications to run on Windows.


Technically not a programming language, but a scripting language that lets the browser do the heavy lifting, JavaScript is a very common language and relatively easy to pick up. It’s used on most websites to update content, control multimedia and animate images among other possibilities. It's an evolving language and its capabilities are always changing. JavaScript is often grouped with CSS and HTML as the basic pillars of building websites. Being familiar with all three of these will improve your odds with smaller digital agencies as you can likely build a website independently.


Not to be confused with JavaScript, Java is a platform with many benefits. It rose to fame for its ability to build 'applets', programs that would run inside of a web browser. This made it popular for making flash games and applications as the web rose in popularity, and people worked out new possibilities, one of the most famous uses of Java is a little game called Minecraft. Despite being released in 1995, Java is still a language for the future. Android Wear smartwatches use code written in Java. With more and more household devices being hooked up to the internet, Java's strength of 'write once, run anywhere' makes it a strong contender for writing the next smart toaster.


Structured Query Language is primarily used to retrieve information from a Relational Database. A Relational Database is a system where multiple tables of data are stored and interact together, for example a book shop would have a customer database of names and addresses, but also a book database, with authors, titles and genres. SQL is generally the preferred language to collect data from all these sources, and present it as simplified reports and meaningful information. With the rise of data analytics, being proficient in SQL is valuable to many businesses, not just tech but any modern enterprise that captures data of any kind.


A modern and versatile language, Python is used for web development, data science and scripting. Used by NASA and Google, one of the more exciting uses of Python is machine learning. The possibilities of machine learning are almost endless, it's essential to facial and image recognition, social media feeds, neural networks, self-driving cars and so much more. Python is comprehensive and takes a long time to learn, but it's designed to be simple to read and with so many possibilities that many people find themselves motivated to learn by their own interest rather than by necessity.

We hope this has cleared up some of the options available to you and will give you a better understanding of how to progress. If you’re ready to take the next step in your career, we have many opportunities for developers in all kinds of languages, find them on our vacancy page
