When to Use What Coding Language

originalThere are literally hundreds of coding languages. Most serious coders know a few; I doubt anyone knows all of them – which is totally fine, because the languages you need to know will depend on the kind of work you hope to do.

So, okay, yes, the fundamentals of programming transcend the variances between coding languages. That makes adapting to a new type of coding a little bit easier. But if you’re going to work on an Android app, it makes sense to use the coding language that is its basis. Same can be said for creating Apple apps or building websites or working with Microsoft…

So, what do you need to know?


JAVA is one of the most widely used and easy-to-understand languages out there. It first appeared in 1995 and was used for building interactive TV applications. The code was designed to be simple and secure and includes big sections of boilerplate code, which, though its flexibility is reduced, increases a programmer’s ability to catch errors quickly. It’s also highly portable, which is why it became the basis for Android and why so many big companies – particularly banks and e-commerce sites – use it to build their websites.


In 2000, Microsoft released a competitor to JAVA called C#. It’s robust in the same way as JAVA, which is also simple to use and portable. It’s built for internationalization, which makes translating languages a lot simpler. The similarities it shares with JAVA explain why Windows apps are created using it and why big companies similarly choose it for their websites and interfaces. However, while the code integrates well with its parent Microsoft, it does not do so well with other platforms as it’s compiled on the Common Language infrastructure, which is mostly used on Windows.


A relatively new language, Swift first came onto the programming scene in 2014 as an improved amalgam of C and Objective-C. As the name implies, it was designed for quick coding so that programmers could experiment more rapidly in Interactive Playgrounds and REPL. The language is used mostly for designing iPhone and Mac apps, and developers describe it as “easier” and “more flexible” than its competitors and predecessors. However, it suffers from its age. There isn’t a wealth of information available about Swift, and because of that, bugs and errors have still yet to be identified and can make problems hard to solve.


It has been more than 20 years since Python was introduced, and it’s still one of the most popular scripting languages out there. Developers and programmers use it to build websites, software, games, desktop GUIs and provide database access. It’s exceptionally popular amongst academics and Google (and also NASA). But even though it’s an old favorite, it is still somewhat slow and uses whitespace that can occasionally cause problems.


Coders use Ruby for building simulations and Web applications. Because it works with the rapid development framework Ruby on Rails, it’s becoming a more popular option (despite first appearing in 1995). It’s a particularly good option for startups. Airbnb built its platform on Ruby, as did Scribd and Github. But when it’s run on a computer, it can be slow. Also, because coders can get the same result with Ruby using different routes, it can make deciphering a previous coders work difficult.
