Hundreds, if not thousands of programming languages exist, however there are only a handful that developers rely on to get the job done.

In this post, we will be talking about the most popular programming languages used in today’s web development ecosystem. Popular developer forum stackoverflow posted this chart highlighting popularity among over 70,000 respondents. JavaScript takes the top spot again, followed by HTML & CSS.


GitHub, the code sharing site used by millions of developers globally also states JavaScript as the top programming language used and that has been the case for the last 4+ years on their platform.

GitHub’s annual Octoverse report provides insight into the happenings of the software developer world. While its easy to conclude that JavaScript is the top programming language, others exist and are widely used and highly effective in certain applications.


  1. C++

An extended version C, C++ is an object oriented low-level programming language that dates back to the 1970s. C++ is fast providing speed that high level languages like Java and Python can’t achieve.  As the core language in many operating systems, browsers and games, C++ is still widely used and taught.

  1. PHP

Hypertext Preprocessor (or PHP) was built for web development and is an open source, server-side scripting language used also for developing web applications. Dynamic and interactive, PHP powers some of the largest and most well known sites like Facebook.

  1. C#

Pronounced C Sharp, this object-oriented programming language was developed by Microsoft for building enterprise level applications and software used by large organizations. Both C++ and C# are object-oriented languages, although C++ is considered a harder language to work with

  1. Python

A powerful high-level programming language, Java has experienced a sharp increase in popularity and set to contunue. Due to its multi-purpose nature, Python is used for a wide range of tasks from machine learning to web development, data analysis and more. On GitHub, Python surpassed Java with more than 40% more pull requests in 2017 than the year prior. Stackoverflow refers to Python as the “fastest growing major programming language”

  1. Bash (Unix Shell)

A Unix shell and command language, Bash (Bourne Again Shell) is widely distributed as the default login shell for most Linux distributions including Apple’s macOS accessed by “Terminal”. Bash is a sh-compatible shell that makes use of key features from the Korn shell (ksh) and C shell (csh).

  1. Java

Not to be confused with JavaSctipt, Java is a general purpose computer programming language that was designed to look and feel like the C++ language. Developed to have as few implementation dependencies as possible, Java can be used in multiple applications including but not limited ot: IoT, enterprise architecture and cloud computing.

  1. SQL

Structured Query Language (SQL) is a standard computer language for relational database management and manipulation. With a well defined set of standards, high speed and interactive language, SQL remains the top database technology being used today.

  1. CSS

Cascading Style Sheet (CSS) is used to format the layout of web pages and can be used to define text styles, table sizes and many more parts of web page that previously had to be defined in HTML. CSS is a cornerstone technology that’s able to control the layout of multiple web pages all at once making it a unique and time saving programming language.

  1. HTML

Hypertext Markup Language (HTML) is the standard markup language for web pages and applications. HTML is used to to define the structure and layout of a Web document by using tags and attributes. Along with CSS and JavaScript, HTML makes up part of the cornerstone technologies powering the web today.

  1. JavaScript

Abbreviated JS, JavaScript is a high-level interpreted programming language that can be characterized as dynamic, weakly typed, prototype-based and multi-paradigm. Written into an HTML page, Javascript can update and change HTML and CSS, it can also calculate, manipulate and validate data. Together with CSS and HTML, JavaScript is a cornerstone technology that is the most popular language used today for its features and flexibility.

And thats it, JavaScript takes the top spot yet again due to its functionally and wide range of capabilities. Together with HTML and CSS, JavaScript powers many of the web pages and applications you use every day, including this website.
