No doubt that software development is one of the most lucrative fields right now, and since 2018, we have seen 21% growth in programming jobs. The average annual salary of an intermediate software developer is $106,000 that is more than any other lucrative job.
Various programming jobs are available globally because different companies and software development require different programming languages. But that’s not why you should learn other programming languages.
If you know more than one, your scope for pursuing different types of software development will grow. But if you don’t have any previous experience with software development, then getting a career in the field will be impossible. It does not matter whether you are new to programming languages or learning a new one.
This list of 10 Best Programming Languages to Learn in 2021 will help you out. These programming languages mentioned here are high in demand and relatively easy to learn. So, let’s check them out.
Python is one of the easiest programming languages you can learn in 2021. The average annual salary of a software developer who uses the Python programming language is around $120,000, and there are about 19,000 types of jobs available in the field. We like Python and position it first on our list because it is a free, open resource, easy to integrate into applications, user-friendly, and for its support modules.
Python can be easily used in machine learning and deep learning applications and create 2D and 3D image applications, video games, and computational applications such as FreeCAD and websites including YouTube. Python is easy to learn both by beginners and those who already have knowledge regarding programming languages.
You can even integrate Python with other programming languages such as C and C++. Start-up companies primarily use Python because it is easy to use and does not come with any cost.

Microsoft developed C# followed by C and C++, and this one became instantly popular in the 2000s because it is the first programming language that supports object-based programming. C# is a widely popular programming language that supports the .NET framework, but C# has more similarities with C++ than with Java. With C#, you can create compatible Android, iOS, and Windows applications.
C# also takes help from Microsoft Visual C++ for creating backend websites such as Visual Studio, MarketWatch, etc. If you want to learn C#, you need the basic knowledge regarding how to write codes because complete beginners cannot learn this language due to its complexities than other programming languages.
The best thing about C# is it supports cross-platform applications such as Windows, Android, iOS, and you can create smartphone and enterprise applications with it easily. If you can compare C# to anyone, it would be Java, but these two are not related because one supports Sun Microsystems and is available for Microsoft’s .NET initiative. Java has a huge ecosystem, while C# creates software for Microsoft.
- The number of jobs available is 18,000, and the average salary is $97,000 per anum
- C# is more secure and faster than C.
- It is totally integrated with Microsoft.
- You can use C# for game development and game consoles.
C and C++
C and C++ are highly professional programming languages that you can use in client/server applications. With skills in C and C++, you can earn up to $76,500 per year.
- Both C and C++ are for intermediate, advanced, and beginner-level developers, but advanced developers can only grasp C.
- C and C++ support mobile and desktop application development and serve as some of the world’s highly proficient languages.
- C++ offers more control over the development process than any other programming language.
- C is not ideal for mobile application development
- C++ does not support run-time checking, including identifying errors during the development process.
Another open-sourced programming language is PHP that was created way before Java and C# in 1990. Developers think that learning PHP is mandatory because popular websites like Facebook and Yahoo are based on PHP only. Developers mostly use PHP to maintain server-side scripts, but PHP also allows you to write command-line scripts.
If you have advanced-level knowledge regarding PHP, you can use that for desktop applications. Many beginner developers think that PHP is the easiest programming language of all. If you want any help regarding the same, you can get into many online communities dedicated mainly to PHP programmers.
You will find most answers to your questions related to programming with PHP, the communities serve frameworks, libraries, and various automation tools. The average salary of PHP developers is $81,000 per year, but unlike other programming languages described in this post, it only has 7,000 opportunities.
- Easy to learn
- Oldest and most reliable programming language
- Helps with server-side ecosystems
- PHP is not that popular.
R is another open-sourced programming language that is slightly developed than the S language. You can use most codes written in S in the R language. R is perfect for machine learning applications and statistical analytics, and you can utilize this programming language in different operating systems, including Ubuntu, Windows, Android, etc.
Companies use R to utilize their vast datasets, and that’s why developers who are experts in R are in high demand. R can also help with linear and nonlinear modelling, virtualization, testing, calculation, analysis, etc. The datasets that R helps you monitor can be both structured and unstructured, but it is not an easy language to be learnt by beginners.
R has some complexities, unlike other programming languages. Still, there are active communities of R developers who can help you with tools, coding skills, etc., when you are learning R.
