Why We Have Different Programming Languages

What is a programming language? A programming language is a set of commands. It includes instructions and other syntax. It is also used in creating programs.

Languages that programmers use to write code are called “high-level languages.” In addition to this, languages that are directly recognized by computer hardware are called “low-level language.”

High-Level Language

High-level languages allow programmers to create source code by using symbols and descriptive words. Many high-level languages are similar enough that programmers can easily understand source code written in multiple languages. However, they are more complex than the languages the computer understands.

Low-Level Language

Machine language and assembly language make up low-level languages. It is made up of binary codes. These codes are understood by the computer’s central processing unit (CPU) only.

Assembly language, on the other hand, is a set of basic instructions that are harder to read than high-level language. In some sporadic cases, a basic program may be coded by the programmer. This is to ensure that it efficiently operates.

Purpose of the Different Programming Languages

There are different programming languages because they do different things to some degree. There are cases where something could have written the same way in multiple languages. However, you picked the one that you prefer.

Another reason is, some programming nerds thought they could make a better language. One that will, most likely, reflect modern needs and styles. So they did. Hence, allowing the language to gain steam. It is a miracle of sorts.

Particular approaches can only solve some issues. Different languages have different strategies to solve problems. Some are efficient and have more advantages to use over others.

In a nutshell, many of these languages are perfectly suitable for use and will continue to be used and developed in the future.

Types of Programming Language

The Functional Programming Language

Functional programming language typically uses stored data, frequently avoiding loops in favor of recursive functions. The primary focus of the functional programming language is on the return values of tasks. 

The Logic Programming Language

These types of languages let programmers make declarative statements and then allow the machine to reason about the consequences of those statements. In a sense, this language doesn’t tell the computer how to do something but employing restrictions on what it must consider doing.

The Object-oriented Programming Language

This programming language views the world as a group of objects that have internal data and external accessing parts of that data. One of the main principles of the object-oriented programming language is an encapsulation that everything an object will need must be inside of the purpose. 

The Scripting Programming Language

The scripting programming languages are usually procedural and may comprise object-oriented language elements. However, they fall into their category. They usually are not full-fledged programming languages with support for the development of large systems.

To Wind Up

Some languages are more accessible for a human being to read, which makes it easier for one programmer to collaborate on another programmer’s code. Other languages allow indentation as well. However, as a stylistic choice, and not as a requirement.

Still, other programming languages are  are compiled. In other words, the program must be processed by a pre-processor. Likewise of a compiler, and linker before the computer can execute it. It executes the program’s instructions without compiling them to machine code first. However, the interpreter sometimes parses the program to an intermediate language. It is, therefore, resulting in optimization. Hence, the performance is never as fast as the compiled machine code.
