Languages Still in Great Demand

One big challenge of working in IT will always be adjusting to new technologies disrupting existing ones. C languages replaced Pascal. Swift replaced Objective-C. The upgrade to new languages can be worthwhile, but abandoning some existing programming languages before their expiration date may be preemptive.

The half-life on some coding languages is stunning. Rather than abandoning long-standing programming languages, determine which have staying power and which are slated for retirement. Here are a few of our projections for the near future:


Through JavaScript predates almost all of the websites and applications using it, the language still manages to stay in wide use. One reason is that its widespread support across browsers limits most impediments to coding with it. Shifting to another client-side language would take universal acceptance from the main web browsers.

Additionally, a variety of popular JavaScript frameworks have helped contribute to its longevity. As the spine of single page web applications, they have become an increasingly popular skill for developers. Among the top open source launches on GitHub are several JS frameworks including Clipboard.js and React.

Overall, the language remains wildly popular among developers and companies as well. Coding Dojo found that at least 40,000 jobs this year have included JavaScript as an expected skill. In our own experience, we continue to see JavaScript as a programming language that many companies demand.


Few programming languages have remained as hot as Java over the years. The no-frills language allows for code and syntax that are easy to decipher even when a completely different person picks up the project. Plus, Java offers straightforward scalability that attracts many large tech companies to its banner.

How badly do companies want Java proficiency? LinkedIn finds that Java programming experience was one of the top 25 skills that companies and recruiters were looking for on the professional networking site. Plenty of companies in Chicago use Java as a cornerstone of their development toolbox and are always looking for new talent with this stalwart skill.

Even popularity among developers remains strong. According to Dice, Java Developer positions have earned the most applications in their job database since the beginning of January 2016. That popularity is also reflected in the sustained popularity of Java on the TIOBE index, where the most popular programming languages are tracked from year to year.


Predictions about the decline of Microsoft’s C#, built on .Net have long been made, but the popularity of the programming language hasn’t budged much yet. Consistent improvements from one iteration of C# to the next help to keep it a central part of the development sphere. The fact that the language offers a unified type system also helps it to stay afloat.

Many companies are still looking for C# proficiency on their development teams. SitePoint finds that C# is listed in almost one out of every five job advertisements. Additionally, there are a number of early adopters of C# that have continued to use it over the years.

C# remains in the top five programming languages on the TIOBE index, and the 2016 Stack Overflow survey finds that C# is still included among the most popular technologies for 39.9% of developers. In fact, a big part of the reason .Net Developer roles have the second highest number of applications in the Dice database hinges upon C# popularity. This language is not going away any time soon.

Keeping in Touch with In-Demand Programming Languages

The wide spectrum of programming languages makes it all but impossible to be proficient in them all. That’s why prioritizing certain languages over others pays off in the long run. In an ideal situation, you’d be able to canvas enough companies to get a good sample of their changing demands. However, not everyone has the time to watch market trends while doing their jobs and keep their existing skills sharp. That’s when a knowledgeable recruiter can be truly valuable.

At TransTech, our team of IT recruiters maintain extensive networks with companies and IT professionals to remain aware of the latest demand for programming languages. Whether new languages like Swift are on the rise or mainstay languages like Java, JavaScript, and C# remain in demand, we can let you know who is hiring for what in the Chicagoland area.
