10 Best Programming Languages to Learn in 2020 for Job and Future

A programming language can be defined as the set of rules used to send the instructions to the computer systems to speed up the input and output processes and to automate, collect, manage, calculate, analyze the processing of data and information accurately.

It not only enables computer language programmers to develop software programs, scripts, applications, and services but also enhances the powers of computers by creating innovations in information technologies.

The programming language helps the developer to create more intelligent technology and machines for task automation. There are thousands of programming languages in the digital technology industry with each programming language has its own set of grammatical rules and features.

Different programming languages are designed for different purposes. The biggest standoff of the technocrat fresher is to make a decision where to begin or which language one should master doing excel in their career.

Most of the time professional coders also face a situation to learn a new language for individuals to get desire placement worldwide. Sometimes for software development companies, there is a need to make a strategic decision about what programming language should be adopted when starting to build a new software system.

Whatever may be the reason,  this article represents a list of the most popular programming languages across the world to know which languages are ruling the charts. This list of top programming languages is based on the data sourced from the TIOBE Programming Community Index, which is a popular indicator of the popularity of programming languages.

1. Java ​​​​​​​

Java is an object-oriented, platform-independent and secured high-level programming language that includes the combination features of C and C++ with some essential additional concepts.

For the past several years it has secured the first and second positions among the different programming languages according to TIOBE. Java was initially developed by James Gosling initially developed Java in Sun Microsystems (which was later merged with Oracle Corporation).

It is well suited for the development of standalone, web, enterprise, desktopbased GUI, cloud computing services, game engines and by using features like JSP, Applets, AWT and Swing, J2EE, Javabeans JDBC, and Java servlets, etc. The usefulness of Java includes the following

Support for Multithreading
Automatic Memory Management
Stability and massive community
Remote Method Invocation(RMI)
Lowsecurity risk
Good for enterprise computing
Simple, portable, Robust
Multithreaded and distributed

However, it has the following disadvantages

Does not support unsigned data type
Not fastest so  more execution time
More memory consumption
More hardware cost

Career Opportunity: Web developer, Application developer, EJB programmer, Software Developer, Tester, Graphics designer, etc.

2.C Language​​​​​​​​

C is a general-purpose procedure-oriented programming language and is used for writing programs in a wide range of domains, such as operating systems, numerical computing, graphical applications, etc..

It provides “high-level” structured-programming constructs such as statement grouping, decision making, and looping, as well as “low-level” capabilities such as the ability to manipulate bytes and addresses which makes it so much popular till today though it is developed by Dennis M. Ritchie at Bell Laboratories in early 1970.


C language is efficient, fast and easy to understand.
It is a highly portable language.
It has a number of built-in standard functions.
The programming task becomes simple.
C language is a structured programming language.
The modular structure makes program debugging, testing and maintenance are easier.


C does not support OOP concept
No runtime checking in C language.
There is no strict type checking.
It doesn’t have the concept of the namespace.

Career Opportunity: S/W developer, Embedded software engineer, graphics designer


Python is an easy-to-learn powerful objected oriented and widely used highlevel programming language that was initially created by Guido Van Rossum in 1991 and further developed by the Python software foundation. It has the capability of developing a virtual realitybased app, artificial intelligence and machine learningbased applications, web applications, game development, database applications, rapid prototype, GUI programs etc. by using its different features such as NumPy, Pandas, Django, MySQL interfaces. The main pulses of Python include the following:

Easy to use an objectoriented language
An expressive and interpreted  language
Cross-platform language

C#, pronounced as “C Sharp”, is an elegant, general-purpose, modern and object-oriented programming language which was developed by Microsoft led by Anders Hejlsberg and his team within the .Net initiative and was approved by the European Computer Manufacturers Association (ECMA) and International Standards Organization (ISO).

It is a lot similar to Java syntactically and is easy to use for  C, C++ or Java users. It is a type-safe object-oriented language enabling developers to build a variety of secure and robust applications that run on the .NET Framework.

Many types of applications such as Windows client applications, XML Web services, distributed components, client-server applications, database applications can be easily created by using C#.


Automatic Garbage Collection
Better Integration

The article explains briefly about the pros and cons of the top 10  programming languages along with their future scope in career and job prospective, which could provide the direction for the future software profession aspirants in selecting a particular language to learn for their career benefits.

The TIOBE Programming Community index is an indicator of the popularity of programming languages that represents the ratings of different languages based on the number of skilled engineers world-wide, courses and thirdparty vendors. Popular search engines such as Google, Bing, Yahoo!, Wikipedia, Amazon, YouTube, and Baidu are used to for calculation of ratings. A graph has been shown to represent the latest ratings of the mentioned languages for 2020.

The graph shows that Java is in high demand followed by other languages. However, there are more promising and demanding programming languages available in the market and the selection of any language to choose as a career depends on the individual interest and requirement and  TIOBE index is not calculated to represent the best programming language or the language in which most lines of code have been written.
