Programming languages

5 in-demand programming languages and how they're used every day

By DeVry University

More than 500 programming languages are available to create our digital world. Some, like Java, Python and Ruby, are more prevalent than others, and more in demand. 

DeVry’s Computer Information Systems program, teaches programming languages like C++ and Java, giving you the hands-on experience and skills for a career in the technology field. 

Weiting Liu, CEO of Codementor, an online community that supports programmers and coders, says employers are seeking these skills, particularly in these five languages: 



JavaScript is probably the fastest-growing scripting language now because of its versatility. "If you’re going to learn only one programming language, learn JavaScript,” Liu says. Its vast applications make it ubiquitous for programming the front-end (user-facing) and back-end (server-facing, logic aspect) of software as well as mobile applications. 

Often it is used to develop web browsers and computer games. It is used in PDF documents and was integral to the web browser Netscape Navigator and later Internet Explorer. 

All you need to start programming in JavaScript is a web browser. The script gives constant “WYSIWYG” (what you see is what you get – pronounced “whizzy-wig”) feedback in which, for example, coders type the command to change color and the color changes. This immediate feedback shortens the learning curve and makes JavaScript relatively easy for beginners to learn.



Java is favored by large enterprises because of its stability and scalability. It is used to write server-facing applications for e-commerce sites as well as for financial trading and scientific uses. It is also used in Android apps and Blu-Ray DVDs.

Unlike Java Script, Java is a full-bodied programming language. This code is written in an integrated development environment – a type of software that typically provides a source code editor, build automation tools, a debugger and sometimes a compiler. This language is more complex than JavaScript or Ruby, but easier to learn than C++, Liu says.



Ruby is a very beginner-friendly, general-purpose language, according to Liu. It is best known for its use in building web sites because of the popularity of the Ruby on Rails framework. Ruby was developed to streamline web programming tasks, including accessing databases, retrieving information and dynamically generating web pages. 

Startups love Ruby because a lot can be accomplished with a few lines of code. Websites for Airbnb, Hulu, Twitch and other successful sites were built using Ruby. the developer community is big and supportive, says Liu, with lots of online tutorials.



Python is a powerful programming language that is popular in academia and data science. It’s used to build web and desktop applications. YouTube and BitTorrent are written in Python. Because it uses a clear, readable syntax, data manipulation is easy. Therefore, Python is taught in many entry-level computer science classes, Liu says.



Swift is a new, general-purpose language developed in 2014 by Apple for the iOS, OS X, watchOS, tvOS and Linux operating systems. This language is considered safer, more resilient, more concise and easier to learn than Objective-C, which, until Swift, was needed to build native applications for iOS. Some apps for LinkedIn and Yahoo Weather were developed using Swift.
