1. Java
Java will be less popular in 2018 compared to 2017, but still have the upper hand. Java has been around for over 20 years, used by millions of developers around the world, billions of devices are developed in Java, and can run on any hardware and operating system through the Java Virtual Machine. All Android applications are based on Java, and 90% of Fortune 500 companies use Java as the server-side language for back-end development. Java Enterprise Edition 8 and Java 9 were also introduced in September 2017 as the Eclipse Foundation took over management of Java EE from Oracle.
2. Python
Python jobs increased by roughly 5,000 jobs in 2017. It is a general-purpose programming language for web development and a supported language for software developers. It is also widely used in scientific computing, data mining and machine learning. The continued growth and demand of machine learning developers will drive the popularity of Python.
3. Java
Java is still very popular. Over 80% of developers and 95% of all websites use Java to implement dynamic logic on pages. Several front-end frameworks for Java, such as React and AngularJS, have huge potential to grow with the proliferation of IoT and mobile devices, so we're guessing we'll see Java's popularity soon.
4. C ++
From the beginning of 2017 until now, the popularity of C++ has been very small. An extension of the C++ programming language, typically used for system/application software, game development, drivers, client-server applications, and embedded firmware. Many programmers find C++ more complex and more difficult to learn and use than languages like Python or Java, but it is still used in many systems in large enterprises.
5. C＃
C# saw a slight drop in demand this year. C# is an object-oriented programming language designed by Microsoft to run on Microsoft's .NET platform and to be faster and more concise than Microsoft's previous languages. Launched in November, C# 7.2 adds several new features to avoid unnecessary duplication. Like C++, C# is widely used in video game development, and game developers have a good grasp of both languages.
6. PHP
PHP, a scripting language used on the server side, ranked ninth last year and sixth. Most developers use PHP for web development, either adding functions that HTML can't handle, or interacting with MySQL databases.
7. Perl
In our analysis, Perl dropped about 3,000 jobs and remained in seventh place. Perl is very popular with system and network administrators and has become a glue language.
languages that have been steadily growing
There are also some languages that are not in our top seven, but are already very popular in 2017. We have also noticed them, such as:
Swift: Swift, the iOS and MacOS programming language released by Apple in 2014, ranked 14th. This may be partly because many job postings require "iOS" experience without specifically listing the programming language skills required. Swift has grown in popularity since the release of IEEE Spectrum and Stackify.
R: R is number 11 on our list, but we expect our rankings to rise over the next few years. But it turned out to be the "least popular" language in this year's Stack Overflow survey. Its growth in the future may be due to the growth of big data analytics jobs.
Rust: While Rust doesn't top our list, it has been steadily growing according to Google Trends.
