Ranking as per popularity of most used languages in 2021 is as follows:
- Python – Python is one of the most used programming languages and is easy to learn for beginners and for those who do not have a programming experience. With the advent of data science and analytics the requirement of Python has increased manifold, it is now a popular language for machine learning and deep learning applications. It is a free, open source programming language with extensive support. There is availability of support modules, developer community, web services based integration, data structures that are user friendly, and GUI based desktop applications. Python is a language that enables use of different programming styles i.e. functional, object-oriented, reflective etc. when creating programs. Several digital tools that are popular have been developed using this language, these include YouTube, Google search, iRobot machines to name a few. Python is an exceptional programming language which is very expressive. Python is ideal for beginners and experienced alike. The language comes with extensive library support. Over 50% of hiring managers seek candidates who know Python. Python is easily the most demanded programming language of 2021.
- Java – This is one of the most popular languages amongst the developer community that is used very extensively across the globe by many developers. It is used for e-commerce, finance and extensive application development purposes across various domains. It is a very popular general use and object -oriented programming language used develop complex applications. In object oriented programming developers create objects that comprise of functions and data, which is further used to provide structure for programs and applications. Java currently ranks as the third most sought after language by hiring managers globally as of today. There is a reason for the popularity of this language this language is relatively easier to learn and use, this language is very secure and can handle big amount of data. These and some other features make this language a popular language for the online finance sector and for developing multiple applications that are used in this domain of banking, billing and stock market. It is a very versatile language that makes it more popular. No wonder this language is touted as “write-once, run anywhere” language. This is one language that can run on any operating system irrespective of operating system that was used to develop that application. It is thus ideal for developing apps for mobile phones, computers, sensors, remote processors and variety of multiple consumer utility products. Today there are in access of 3 billion devices running applications built with java. Java is also being used on the backend of several popular websites including Google, Amazon, Twitter, and YouTube. New java frameworks like Spring, Hibernate and Struts are in great demand and with millions of developers across the globe there are multiple ways to learn the language. Java programmers have a very extensive support and online community with strong support to solve the problems.
- C# – This is also an open source object oriented language developed by Microsoft in 2002 that is multi-paradigm and general purpose and popularly used. It comprises of generic, object oriented, functional, strong typing, lexically smartly scoped, declarative and component oriented programming principles. C# has a special purpose it has been developed to be used in web development, networking and also software development for distributed environments. If you want to develop complex applications for hosted and embedded systems you can use C# for that purpose. This can be made possible in the environment from complex and advanced operating systems to niche systems that have got dedicated features and functionalities. Because of the features it brings C# is a versatile language as it has the capability to enable development of wide range of applications including mobile apps, web apps, front-end and back-end systems etc. There is also a dedicated built in .NET core machine learning platform, ML.NET. This is a cross platform and an open source ML framework that can be used to develop complex ML applications by .NET developers. Because of the versatility of the language a developer can plan to earn handsome salary post knowledge acquisition of this language. This language is also used for game development and VR in addition to mobile, desktop and web apps.
- Perl – Perl is a dynamic programming language developed by Larry Wall in 1987. This language is high-level, general purpose and highly interpreted. The main purpose for which this was designed was to make Unix scripting for text manipulation and report processing a simpler task. Now Perl is used for many other purposes that include web development, network programming, system administration, and GUI development. Such is the value of Perl that person who knows this language can expect to earn 54 percent more than what an average developer earns thereby giving boost to earning potential. It is worth noting that majority of the programmers who know this language are senior developers. It will be ok to say that learning this language can give a raise to a junior programmer and enhance the earning potential as well. PERL is short form of Practical Extraction and Report Language and is prominently a scripting language that can be used to extract information from the text files and create valuable reports. Most of the programming languages are compiled languages wherein a target machine translates the program, Perl is an interpreted language and an “interpreting” machine locates the code and executes the task as well. Also interpreted programs require more CPU but when Perl is used it creates short scripts that can be processed quickly and CPU may not be required that much. Key point to note is that Perl borrows features from other programming languages as well including C, Shell Script, and AWK. Other thing to note is that its syntax is quite similar to C and it is compatible with XML, HTML and other mark-up languages and also Unicode is supported by it. It also has a database integration interface DBI that supports numerous other databases such as MySQL, Oracle, Postgres and Sybase etc.
