5 In-Demand Programming Languages

Learning a new language can open a world of possibilities. Learning a new programming language can be just as rewarding. But with approximately 256 programming languages known in the world, which ones are worth learning now? And why?

Whether you’re an experienced IT professional or just starting out in the field, it’s always a good idea to stay current and up-to-date with the latest cyber security trends, tools and threats. Fortunately, the Internet is full of incredible cyber security resources that keep you ahead of the curve (and the competition).

Before you dive in, we wanted to draw your attention to one of the metrics we used to convey the most popular programming languages in 2018. “Love Language” comes from the 2017 Stack Overflow Developer Survey and is a measure of the percent of developers who are developing with a certain language and have expressed interest in continuing to develop with it. For example, about 63% of developers currently using Python want to continue working with it in the future.

IEEE Spectrum

With close to half a million members in over 160 countries, the Institute of Electrical and Electronics Engineers (IEEE) is the world’s largest technical professional organization for the advancement of technology. IEEE’s 2018 Top Programming Languages ranks language popularity based on 11 metrics that include social chatter, open-source code production and job postings. The interactive ranking app allows you to filter dozens of programming languages by weights that are most important to you, such as languages that are in demand by employers or languages popular on open-source hubs.

TIOBE Index

The TIOBE programming community index is a measure of the popularity of programming languages. The index is updated once a month. According to TIOBE, the index “is not about the best programming language or the language in which most lines of code have been written.” Ratings are based on the number of skilled engineers world-wide, courses and third-party vendors. Learn how TIOBE index ratings are calculated here.

Stack Overflow Developer Survey

Stack Overflow claims to be the “largest, most trusted online community for developers to learn, share their knowledge and build their careers.” Every year since 2011, Stack Overflow has asked developers about their work preferences, coding habits, professional development and more. The resulting Stack Overflow Developer Survey provides developers rich information about their industry, their peers and themselves.

GitHub Pull Requests

GitHub is the world’s leading software development platform. Millions of developers use GitHub to share code, contribute to open-source projects, develop new technologies and help businesses solve critical development issues. Pull requests are the mechanism for contributing to a project, and as such, a good measure of how many active developers are working with any given programming language. The State of the Octoverse analyzes the projects and people of GitHub in 2017, including the most popular languages by opened pull request.

Dice.com

Dice is a leading career site for technology and engineering professionals. The website advertises approximately 80,000 tech positions daily and generates about two million unique visits each month. We searched the Dice database to see how many positions were advertised for a specific programming language. For example, searching “python” returns over 7,000 positions in the US.

Most Popular Programming Languages in 2018

Python

Python is a general-purpose, object-oriented language, which means it can be used to build just about anything, including web development, system automation and penetration testing. The Python language has easy-to-learn and easy-to-use syntax, making it the perfect language for newcomers to computer programming. In 2014, Python was the most popular language taught in introductory computer science courses at top-ranked CS departments. Python was used to build Instagram, YouTube and Spotify.

C#

C# (sharp) was originally developed at Microsoft as a rival to Java. C# can be used to create almost anything, but is particularly used for building Windows desktop applications. In recent years, C# has also become increasingly popular among mobile developers. Based on the C language, C# is transferable to other languages like Java, Objective C, PHP and C++.
