10 Most In-Demand Programming Languages [Updated October 2021]

Most in-demand programming languages

If you are a coding enthusiast, then you probably know, the world of programming is dynamic. And developers need to evolve with the new coding trends regularly because in-demand programming languages to get a decent job are getting to keep change in the course of a few years.

The evolution of modern technology makes it unpredictable. Maybe a new programming language will rise to fame within a few years, and today’s most in-demand programming languages may become obsolete. No one knows. So the developers are forced to learn new skills to keep updated.

Today the world is running on codes and getting a good IT job, or maybe your dream job in the coding field has become far more competitive, and everyone is in search of skilled coders. Since anyone can start to learn how to code, but be being a master in this field requires talent or constant practice.

So if you are a beginner, practice — learn to code through different approaches, and you know. The internet is there to help you with many programming examples, tutorials, and communities like StackOverflow.

And if you are a pro coder and already got placed in some company — maybe you are an expert in one of today’s most in-demand programming languages, but you don’t know tomorrow which one is going to rise up or which fades away. So brace yourself and start to learn new skills or new programming languages. 

This ranking of top programming languages is based on the TIOBE Programming Community index. If you don’t know, the Tiobe popularity index is an indicator of the popularity of programming languages, which is updated once a month. So we also update this article every month.

TIOBE Programming Community index calculated rating based on searches for a programming language on popular search engines such as Google, Bing, Yahoo!, Wikipedia, Amazon, YouTube, and Baidu.

So here are the top in-demand programming languages of October 2021 — that is going to get you a secure job in coding.

Most in-demand programming languages:

1. Python

For the first time in more than 20 years, Python jumped to no.1 spot beating long-standing hegemony of Java and C, with a rating of 11.27%.

Python is easy to learn and runs everywhere type of programing language. It is used for the development of a range of application types, including Web development, scientific computing, and Machine Learning. Google and Instagram are two big giants among many users of Python. The popularity of the Machine Learning field seeks more python developers.

2. C

C dropped to the second position in the October 2021 popularity ranking, with a rating of 11.16%.

C is a powerful general-purpose programming language developed at Bell Labs by Dennis Ritchie between 1972 and 1973 to construct utilities running on Unix. C is a machine-independent, structured programming language which is used extensively in various applications. It is used to build software like operating systems, databases, compilers, and so on.

It says that C is a base for the programming — because if you know ‘C,’ you can quickly grasp the knowledge of the other programming languages that uses the concept of ‘C’.

3. Java

Java ranked third this month, with a rating of 10.46%.  

Java is the top in-demand programming language for the past few years. This 20 years old programming language is being used by millions of developers and billions of devices all over the globe. Almost every big company is using Java as the server-side language for backend development. And nearly 90% of Android apps are build based on Java. All this makes it one of the most in-demand programming languages of the present and the future.

4. C++

Next on the list is C++, with a rating of 7.50%.

C++, one of the most widely used languages for scripting usually used for system and application software, game development, drivers, client-server applications, and embedded firmware. C++ is being used in many legacy systems at large enterprises that demand more developers.

5. C#

C# ranked in the in-demand programming languages list with a rating of 5.26%.

C# — known as C-sharp — developed by Microsoft, is used in mostly all of their products. C# is mainly used for developing desktop applications and video games. So if you are pursuing to become a game developer, then C# is one of the top programming languages you should learn.

6. Visual Basic

In the ranking list, Visual Basic is in 6th position with a rating of 5.24%. 

Visual Basic is a third-generation event-driven programming language developed by Microsoft engineered to help you productively building type-safe and object-oriented apps. If you want to create .NET apps, then learn Visual Basic.

Visual Basic is derived from the BASIC programming language and intended to be easy to learn and fast to write code with, as it uses a GUI-based development tool.

7. JavaScript

The TIOBE Programming Community index rating of JavaScript for this month is 2.19%. 

JavaScript is a prototype-based, multi-paradigm, single-threaded, dynamic language, supporting object-oriented, imperative, and declarative (e.g. functional programming) styles.

JavaScript is used over by 80% of developers and by 95% of all websites. JavaScript plays nicely with other languages and is used in a wide variety of applications. Because of demand, like Java, JavaScript is also one of the most in-demand programming languages of the present and future.

8. SQL

SQL ranked 8th position with a rating of 2.17%.

SQL — Structured Query Language — is used to communicate with a database. SQL is a standard language for storing, manipulating, and retrieving data in databases. All the Relational Database Management Systems (RDMS) like MySQL, MS Access, Oracle, Sybase, Informix, Postgres, and SQL Server use SQL as their standard database language.

9. PHP

PHP ranked in 9th position with a rating of 2.10%.

PHP is the most in-demand scripting language designed for developing dynamic web pages. Using PHP writing a database-enabled web page is incredibly simple, and integration with different databases makes this language powerful. This open-source programming language provides a cost-effective way of building dynamic websites. So there is good demand for PHP developers across the globe today.

9. Assembly Language

Assembly Language ranks 10th spot with a rating of 2.06%. Back in October 2020, the programming language was ranked in the 17th position.

Assembly Language is a programming language that is a direct translation of machine code — this code is interpreted by the microprocessor — so that it can be understood by human beings; therefore, it is a low-level language. The Assembly Language allows an optimization that is not achieved with medium and high-level languages. Since Assembly Language is strongly conditioned by the architecture of the computer it supports, programmers do not usually write large programs in assembler but instead use this language to fine-tune important parts of programs written in higher-level languages. Assembly Language is still important as it offers the programmer full control of the machine and, as a result, generates compact, fast and efficient code.

So which of these top in-demand programming languages are you mastered in or going to learn soon?
