Introduction

If you don’t know that what is programming language but want to update your knowledge about programming because of its popularity in the whole world then this article will be fruitful for you. This article can be very helpful for you if you are beginner in the programming field or want to adopt programming as a career opportunity in future. So, no matter from which field of life you belong, this article will be a helpful for you.

What is Programming Language?

Program is a set of instructions that are given to the computer for execution. These instructions tell your computer what to do and how to do.

Let’s understand it with real life example. Suppose you want to prepare a lunch with some new recipe. You read recipe and act according to that recipe to prepare a lunch.

So, in this case you are acting as a computer and author of recipe is a programmer who is providing the set of instructions and you are following that instruction in the same manner to prepare your lunch. If the instructions are clear or simple then it will be easy for you to follow and implement them but if instructions are complex then maybe you fail in implementing them and there will be chances that you will ruin your lunch.

Computers only understand binary language ( 1’s and 0’s). It is difficult for us to give the detail instructions in binary language to computers. Therefore, to overcome this problem we have multiple programming languages that are easy for us to understand.

Computer programming languages are series of symbols or instructions that convert and translate our thoughts into an instruction that computer can understands. If we talk about what are the reserved words with a programming language. Then most of the programming languages contains reserved words that has some specific meaning in language.

How many Programming Languages are there?

There may be a question in your mind that how many programming languages are available. There are about 9000 programming languages exist. Out of these many languages are specific for particular machine that’s why their use is very limited. There are about 150 programming languages which are considered as popular languages.

Why there are so many programming languages?

The reasons of these so many programming languages is that we have different type of systems and digital devices that performs different functions. We have different programming languages that help us to perform specific device functionality.

What are high-level and low-level languages?

 If we talk of type of programming language then languages has been categorized into two types that includes; high level and low level. High level languages are easy to understand while low level languages are difficult to understand.

Low level programming languages are very close to machine code or binary that’s why it is difficult for human to understand. Low level languages are very fast and give precise control over computer functions. Assembly language and machine language are the example of low-level language.

High level programming languages are close to human communication. It uses such words that are part of our daily life. For example; object, order, class, request etc. It’s closeness to human communication is one of the main reasons that make it easy to learn and understand. Computer need to translate high level code into machine language. Python, Ruby, java, PHP, Perl etc. are the examples of high-level language.

Most of the popular languages are object oriented based and It is very easy to manipulate and reuse them. Java, Python, LISP, C++, Perl are high level as well as object-oriented languages.

Some programming languages are functional programming that based on mathematical functions and use linear mathematical logic. Most of them are use in big data analytics and list processing applications.  Haskell, SML, Clojure, Clean, SML, Scala, F# and Mathematica are examples of functional programming languages.

10 Most Popular Languages with Uses

If you have a question in your mind that which programming language is best

C

C programming language is high level procedural language that is most widely used language. It used to create versatile language mainly system application. It can also be used to create games, graphics and applications that requires much calculations.

Python

 It is easy to learn and it is also an object-oriented high-level programming language. It is considered as one of the most popular programming languages. There are so many applications of this versatile language that includes; web applications, artificial intelligence and machine learning.

Java

It is popular object-oriented high-level programming language. It is versatile as well as general purpose language and similar to java script and python. It mainly uses in business software, web applications and mobile applications.

JavaScript

Most of the people aske is javascript a programming language? The answer is “Yes”. It is not directly related to java. It is called JavaScript because its script is almost similar to java. It is also high-level object-oriented programming language and most of the major web browsers have JavaScript support. If you are interested in client-side web browser coding then this language can be beneficial for you.

PHP

PHP is an abbreviation of hypertext preprocessor. It is easy to use programming language and it mainly use in web coding. It can be used to manage database and dynamic web content. It is also high-level object-oriented programing and sever side scripting language. It mostly uses with combination of JavaScript.

SQL

SQL stands for structured query language. It is domain specific language that mainly designed to manage data in database. Every programmer should have basic knowledge of SQL. Server developers, database administrators and software developers use SQL to perform their professional development tasks. Now a days its also use in big data mining and data analysis.

R

R is low-level functional programming language that mainly focus on statistical computing and graphical techniques. Statisticians and data miners use this language for statistical software development and data analysis package development. It also uses by demographers, data scientist and insurance actuaries to gain statistical insights.

Kotlin

Kotlin is an object oriented and functional programming features support statically typed general-purpose language. It supports all java libraries and it is very easy to learn and understand. It mainly uses in mobile application development, web development and desktop application development.

GO

The demand of this programming language has been increasing among developers with the passage of time. It is statically typed general purpose programming language that is developed by Google. Its syntax is similar to C. It contains the features like garbage collection, type safety, dynamic typing and high performance. It mainly uses in distributed and cloud computing.

Scala

It is general purpose programming language that supports object oriented and functional programming paradigm. It uses in web development, data science and machine learning.

This was a short introduction about 10 most popular languages with their uses but there are so many other languages that can be learn. But main thing that you need to keep in mind that before start learning any programming language to have to identify the main purpose of learning programming language so you can focus on that specific language.
