Best programming languages to learn in 2021

Programming starts a long time ago to control machines. When humans invent machines it was like a body without a brain and programming is the process of giving a dead machine life. We can consider programming as the brain of a machine, which controls the machine.

Programming Languages

Programming starts with machine language. which is a binary format that includes only ‘0’s and ‘1’s. Now itself most of the machines can read-only binary language and we have to convert the high languages to binary using the compiler and assembler.

When time flies, the need for more complex machines and more complex programming emerges, and then the high-level programming languages come in to picture. The high-level programming language will be

  1. Independent of the platform
  2. Close to human language
  3. Easy to understand
  4. Needs a compiler
  5. Machine independent

What are the types of programming languages?

When the high-level programming language comes into the scene, there come many methods on how the programming is done. We can divide the programming languages into five types.

History Programming Languages
  1. Procedural oriented language: It has a well-defined structure and procedure to write a program. Example: C, FORTRAN, Pascal, etc.
  2. Functional oriented language: In functional oriented language, more importance is for functions and the expression and declaration for example lambda calculus is the foundation of functional oriented language.
  3. Object-oriented language: Object-oriented language is based on objects and class. Every function is written in a class, which can be called repeatedly by its object name. It gives the features like class, inheritance, encapsulation, etc. example: Java, C++, Python, etc.
  4. Scripting language: It is mainly used in web applications, games, and multimedia. It uses the interpreter instead of the compiler, doing the conversion in runtime.
  5. Logic Programming language: it is the latest language, which includes AI. 

Which language is good to study in 2021?

Now you know the programming languages, and will be in a dilemma that which programming language to study?

We here describe the best and popular programming languages and describe why they attained that position and how much difficult to study that which the job opportunity.

1. Python

We prefer python is coming up strong in modern programming because of the wide range of applicability and close to the human language. Python is a scripting language and it is used in 2D and 3D animation software like blender, web applications, creating games, popular websites like Quora, Pinterest, Instagram, etc.
