TOP 10 Programming languages that are trending in 2021

Top Programming Languages

Nowadays, people are willing to learn programming languages to get better job opportunities in today’s technology dominant world. To make life simpler, technology facilitates diverse sectors. To provide the best Mobile App Development Services to your clients, programmers, developers, and coders must stay updated on the programming languages that are being used across the globe. Without further ado, let’s get started!


Python is an open-source, high level and interpreted programming language. It is a very simple language and beginners can easily learn this language due to its coherence. This language can be used for the machine learning process as it’s is user-friendly.

Advantages of Python

  • Pliable in nature
  • Scripted rather than being compiling
  • It can be read easily
  • Support multiple platforms and systems
  • Enclose official instruction along with the documentation

Disadvantages of Python

  • Not reasonable for mobile computing
  • Various important basic concepts are hidden
  • Basics of programming are not available
  • Slow by the excellence of being interpreted programming language


Java is an object-oriented programming language. It is used on a large scale by organizations because of its high scalability. It can be used for designing purposes by developers or programmers to design the backend designing for websites.

Advantages of Java

  • Collection of open source libraries
  • Automatically allocate the system’s memory
  • Garbage collection clears the cookies and cache
  • The code is based on the object-oriented programming language
  • Support multithreading programming and distributed computing

Disadvantages of Java

  • Slow and has poor performance
  • Provides no backup facility
  • Verbose and complex codes
  • Requires memory space


C/C++ is the foundation for all programming languages and it will still be on the list of top 10 programming languages of all times. The explanation why the different programmers choose this language is that it is fast and accurate.

Advantages of Java C/C++

  • C/C++ is object-oriented programming language
  • It has a rich function library
  • Most preferred language for designing purpose
  • Code for designing purpose is easy 
  • It is a powerful, efficient, and fast language

Disadvantages of Java C/C++

  • The greatest drawback is that the language is not adequately qualified to address the complexities of contemporary coding.
  • There is no feature including dynamic allocation of memory and collection of garbage.
  • There are issues related to buffer overflow and memory corruption.


 Kotlin is a “pragmatic” programming language initially developed for JVM (Java Virtual Machine) and Android that incorporates object-oriented and functional programming functionality for general-purpose, free, open-source, statically typed. It focuses on support for interoperability, protection, transparency, and tooling.

Advantages of Java Kotlin

  • Maximizes the productivity of the teams
  • Easy to learn and reliable
  • Improved run time execution
  • Interoperability with Java
  • Less buggy         

Disadvantages of Java Kotlin

  • Still not Java
  • Slow compilation speed
  • Limited learning resources
  • Fewer Kotlin experts for hire


JavaScript is a prototype-based, lightweight, interpreted single-threaded, and dynamic language. It can function both as an object-oriented language and procedural language.

Advantages of JavaScript

  • Extended functionality
  • Simplicity, interoperability, and versatility
  • Exceptionally adaptable
  • Used for building dynamic applications
  • Give a more extravagant interface to a site

Disadvantages of JavaScript

  • Client-side security
  • Permits only single inheritance
  • Unavailability of copy or similar method
  • As every browser has different functionality

Go Language

Go Language is also known as Galang language is the statically typed, compiled programming language designed at Google. It is an open-source programming language that makes it easier for developers to build simple, reliable, and efficient software.

Advantages of Go Language

  • It is easy to learn
  • Assisted by Google
  • Very fast in learning
  • More secure because of its typing style
  • Compiled directly to machine code

Disadvantages of Go Language

  • Lack of adaptability
  • Absence of manual management memory
  • Runtime safety is not that good
  • No support repositories
  • Complex programming results


Ruby is a high level, dynamic, interpreted, and general-purpose programming language. It was planned to provide a sentence structure that human beings can comprehend and can comply with from an object-oriented engineering point of view. The procedural and functional documentation of programming is its basis.

Advantages of Ruby

  • Sticking to standards
  • Provide many helpful libraries and tools
  • Direct and quick production of web apps
  • Refined, durable, and simple to unravel

Disadvantages of Ruby

  • Lack of flexibility
  • Ongoing growth
  • Price of failure
  • Stability is affected because of a little run time


For creating iOS software, Swift programming is generally used. The demand for iOS devices is growing day by day in the industries. Swift has now become the number one language for Apple applications, replacing Objective C.

Advantages of Swift

  • It is safe and secure
  • Easier to scale the product and team
  • Improved safety and performance
  • Decreased memory footprint
  • Automatic memory management
  • Vibrant open source community and learn ability

Disadvantages of Swift

  • The language is still quite young
  • Lack of support for earlier iOS versions
  • Limited talent pool
  • Poor interoperability with third-party tools and IDEs
  • Use modern programming methodologies and standards


Rust is a programming language with several paradigms structured for success and protection, especially safe competition.[15][16] Rust is syntactically similar to C++.

Advantages of Rust

  • Fast and memory-efficient
  • Friendly compiler with useful error messages
  • Coming from dynamically typed languages
  • Coming from other systems programming languages

Disadvantages of Rust

  • Slow and leaky
  • Invasive and Dysfunctional
  • It’s not webscale
  • Less efficient code as compared to C++ and especially C

Dart is client optimized language developed by Google. It can be used on multiple platforms to build mobile, desktop, server, and web applications. 

Advantages of Dart

  • Open-source language
  • Easy to learn
  • Ensures enhanced productivity

Disadvantages of Dart

  • Limited resources to learn
  • Immature
  • New to programmers
