Top Programming Languages 2021

Technology has a dramatic impact on our lives. As most individuals started to efficiently program computers, programming languages became more potent with luxurious features and high functionality.

Programming languages are used to instruct the computer in a language that the computer understands.

It’s a set of commands and instructions that empowers humans to instruct and control machines efficiently. It can help you create a software program integrating rich features via keeping up with the recent trends.

Mainly, programming languages are categorized into two categories one is a high-level programming language, and the other is low-level language.

High-level programming languages are designed to be easy to read and understand. It enables developers to write source code in logical words or symbols. The best example of the high-level programming language is Java, C++, PHP, and a lot more.

A low-level programming language provides developers with a minimal amount of abstraction at the smallest possible cost to perform and offer efficiency. A program written using low-level programming language can be made to run very quickly with a small memory footprint. The best example of the low-level programming language is assembly language.

So far, thousands of different top programming languages have created. You must be wondering which is the best programming language in 2021? Most of the programming languages consist of instructions for computers to implement algorithms. With several programming languages available, selecting the one can be a daunting task. Furthermore, it has become essential to possess programming knowledge for individuals to get desired placement worldwide.

top 10 programming languages

As per the Stackoverflow, there are 67% of programmers who like to write code in Go language and the other 15% want to try it after Python and JavaScript. Google also declared to work with the Go language, hence we can say the future is with the Go language due to its most attractive feature ‘simplicity’. 

Even after having so much popularity, Go lang is not in so much demand of developers as per shown in this graph released by Github. According to Octoverse 2019, this language was not among the top 10 programming languages of the last decade but now, it has 10th place in the list of fastest growing languages.

Types of Programming Languages

Developers use suitable programming languages for their own particular project purpose or syntax they want to use to generate instructions. Here are different sorts of programming languages they use-

Low-level Languages 

Using these kinds of languages offers abstraction from the hardware and are depicted in the binary form that is either o or 1 referred to as machine instruction. Low-level languages also have two types-

  • Machine-level languages 
  • Assembly level languages

High-level Languages

It permits developers to code programs that are not related to the type of computer. These are close to human languages and understandable easily, it’s just that it needs attention for the problem logic. It has advantages like- 

  • Easy to maintain and learn 
  • Portability with the machine-independency 

Everything Considered

Comparing programming languages is a daunting task. Figuring out what is best for you only depends on your requirements and the futuristic approach you wish to follow in 2021. The languages which are fighting for its acceptance this year can be seen in trending programming languages 2021.

All the languages are essential to developing a next-generation app considering the rapid growth of the industry. These are some of the hottest future programming languages 2021  in any industry helping people to undergo a redefining experience.
