The 7 Most In-Demand Programming Languages of 2018

The 7 Most In-Deman ProgrammingLanguages of 2018

Software development is a dynamic field. New and in-demand programming languages, frameworks and technologies can emerge, rise to fame, and then fade away in the course of a few years. Developers need to constantly be learning new skills to stay relevant. At Coding Dojo, we’re continually evaluating which programming languages are in high demand from employers so we can prepare our students to enter the job market. There are many ways to measure a programming language’s popularity, but we believe examining job demand is most useful because it shows developers the skills to learn to improve their career prospects.

1. Java

Java decreased in popularity by about 6,000 job postings in 2018 compared to 2017, but is still extremely well-established. Java is over 20 years old, used by millions of developers and billions of devices worldwide, and able to run on any hardware and operating system through the Java Virtual Machine. All Android apps are based on Java and 90 percent of Fortune 500 companies use Java as a server-side language for backend development. Java Enterprise Edition 8 and Java 9 both launched in September 2017 as the Eclipse Foundation took over managing Java EE from Oracle.

2. Python

Python grew in popularity by about 5,000 job postings over 2017. It is a general-purpose programming language used for web development and as a support language for software developers. It’s also widely used in scientific computing, data mining and machine learning. The continued growth and demand for machine learning developers may be driving the popularity of Python.

3.JavaScript

JavaScript, the grandfather of programming languages, is roughly as popular today as it was in our last blog post. That’s no surprise to us – JavaScript is used by over 80% of developers and by 95% of all websites for any dynamic logic on their pages. Several front-end frameworks for JavaScript such as React and AngularJS have huge future potential as IoT and mobile devices become more popular, so we doubt we’ll see JavaScript drop in popularity anytime soon.

4. C++

C++ changed very little in popularity from early 2017 to now. An extension of the old-school “C” programming language, C++ is usually used for system/application software, game development, drivers, client-server applications and embedded firmware. Many programmers find C++ complex and more difficult to learn and use than languages like Python or JavaScript, but it remains in use in many legacy systems at large enterprises.

5. C#

C# (pronounced “C sharp”) went down slightly in demand this year. C# is an object-oriented programming language from Microsoft designed to run on Microsoft’s .NET platform and to make development quicker and easier than Microsoft’s previous languages. C# 7.2 came out in November, adding several new features geared towards avoiding unnecessary copying. C#, like C++, is heavily used in video game development, so any aspiring video game developers would do well to learn both of them.

6. PHP

PHP, a scripting language used on the server side, moved up to number six in our ranking over number nine last year. Most developers use PHP for web development, either to add functions that HTML can’t handle or to interact with MySQL databases.

7. Perl

Perl dropped by about 3,000 job postings and stayed in seventh place in our analysis. Perl 5 and Perl 6 are both chugging along and Perl continues to be popular for system and network administrators and as a glue language.
