TechnoPeri: Most Popular Programming Languages to Learn in 2020

Top Most Popular Programming Languages to Learn in 2020.

Every year StackOverflow publishes insights on the developer survey. These insights cover lots of different aspects of the developers around the globe. It includes developers' background, popular programming languages, web frameworks, libraries, tools, databases, platforms in the software industry.

From the last 7 years, JavaScript is the most popular & commonly used language but Python is the fastest-growing language. There’s no change in C#, Php & C++ position but Go & Kotlin gained popularity.

There are many programming languages present in the market. Every language has its advantages and disadvantages. So choosing the best programming language on which you should focus can be difficult.

This is also one of the main reasons why I am writing this article. The main motive of this article is to tell you guys the list of best programming language on which you should work in 2020.

1. Python

Python is one of the best programming languages every developer should learn this year. The language is easy-to-learn and offers a clean and well-structured code, making it powerful enough to build a decent web application.

Python can be used for web and desktop applications, GUI-based desktop applications, machine learning, data science, and network servers. The programming language enjoys immense community support and offers several open-source libraries, frameworks, and modules that make application development.

For instance, Python offers Django and Flask, popular libraries for web development and TensorFlow, Keras, and SciPy for data science applications.

Though Python has been around for a while, it makes sense to learn this language in 2020 as it can help you get a job or a freelance project quickly, thereby accelerating your career growth.

2. C#

C# is pronounced as "C-Sharp". It is an object-oriented programming language provided by Microsoft that runs on .Net Framework.

By the help of C# programming language, we can develop different types of secured and robust applications:

Window applications
Web applications
Distributed applications
Web service applications
Database applications etc.

C# is approved as a standard by ECMA and ISO. C# is designed for CLI (Common Language Infrastructure). CLI is a specification that describes executable code and runtime environment.

C# programming language is influenced by C++, Java, Eiffel, Modula-3, Pascal etc. languages.

Usage applications: Widely used in Enterprise Cross-Applications Development, Web Applications.

3. Java

Java is a programming language and a platform. Java is a high level, robust, object-oriented and secure programming language.

Java was developed by Sun Microsystems (which is now the subsidiary of Oracle) in the year 1995. James Gosling is known as the father of Java. Before Java, its name was Oak. Since Oak was already a registered company, so James Gosling and his team changed the Oak name to Java.

Applications of Java

According to Sun, 3 billion devices run Java. There are many devices where java is currently used. Some of them are as follows:

Desktop Applications such as acrobat reader, media player, antivirus, etc.
Web Applications such as irctc.co.in, javatpoint.com, etc.
Enterprise Applications such as banking applications.
Mobile
Embedded System
Smart Card
Robotics
Games, etc.

4. C#

C++ is a general-purpose, case-sensitive, free-form programming language that supports object-oriented, procedural and generic programming.

C++ is a middle-level language, as it encapsulates both high and low-level language features.

Applications of C++

By the help of C++ programming language, we can develop different types of secured and robust applications:

Window application
Client-Server application
Device drivers
Embedded firmware etc.

5. Javascript

JavaScript (js) is a light-weight object-oriented programming language that is used by several websites for scripting the webpages. It is an interpreted, full-fledged programming language that enables dynamic interactivity on websites when applied to an HTML document. It was introduced in the year 1995 for adding programs to the webpages in the Netscape Navigator browser. Since then, it has been adopted by all other graphical web browsers. With JavaScript, users can build modern web applications to interact directly without reloading the page every time. The traditional website uses js to provide several forms of interactivity and simplicity.

Although, JavaScript has no connectivity with Java programming language. The name was suggested and provided in the times when Java was gaining popularity in the market. In addition to web browsers, databases such as CouchDB and MongoDB uses JavaScript as their scripting and query language.

Application of JavaScript:

JavaScript is used to create interactive websites. It is mainly used for:

Client-side validation,
Dynamic drop-down menus,
Displaying date and time,
Displaying popup windows and dialog boxes (like an alert dialog box, confirm dialog box and prompt dialog box),
Displaying clocks etc.

6. PHP

PHP is an open-source, interpreted, and object-oriented scripting language that can be executed at the server-side. PHP is well suited for web development. Therefore, it is used to develop web applications (an application that executes on the server and generates the dynamic page.).

Running with PHP is simple
Functional and Object-Oriented Programming
Large Open Source Software Community
A reasonably good system of automation tools available for testing and deploying.

Applications of PHP

Web Applications

Content Management Systems

eCommerce Applications.

7. SQL

SQL was developed at IBM by Donald D. Chamberlin and Raymond F. Boyce. This language was made available publicly in 1979.

Cons:

Powerful query language.
Optimized for large numbers of table rows.
Fast for searching and querying of data.
High availability and consistency of data.
Fast for retrieving data from multiple tables.

Pros:

Difficult to convert data from Objects into database tables
It can only run on a single server, so increasing speed means upgrading hardware.
As SQL databases run on a single server so in case if the server stop working, then the database shouldn't be accessed.

8. Kotlin

Kotlin is a general-purpose, statically typed, and open-source programming language. It runs on JVM and can be used anywhere Java is used today. It can be used to develop Android apps, server-side apps and much more.

Kotlin was developed by JetBrains team. A project was started in 2010 to develop the language and officially, first released in February 2016. Kotlin was developed under the Apache 2.0 license.

Features of Kotlin

Concise: Kotlin reduces writing the extra codes. This makes Kotlin more concise.

Null safety: Kotlin is the null safety language. Kotlin aimed to eliminate the NullPointerException (null reference) from the code. Interoperable.

Interoperable: Kotlin easily calls the Java code in a natural way as well as Kotlin code can be used by Java.

Smart cast: It explicitly typecasts the immutable values and inserts the value in its safe cast automatically.

Compilation Time: It has better performance and fast compilation time.

Tool-friendly: Kotlin programs are build using the command line as well as any Java IDE.

Extension function: Kotlin supports extension functions and extension properties which means it helps to extend the functionality of classes without touching their code.

9. Go programming language

Go language which is also known as golang is developed at Google in 2009 by Robert Griesemer, Ken Thompson, and Rob Pike.

Go is a really fast language as it is compiled to machine code
Its syntax is small compared to other languages, and it's easy to learn.
Offers standard library to provide handy built-in functions for working with primitive types
Go makes concurrent programming easy.

Applications:

Console utilities.

GUI applications.

web applications.

10. Swift

Swift is a general-purpose, multi-paradigm, compiled programming language for developing iOS and OS X tvOS, watchOS applications. It is developed by Apple Inc. It is a powerful and intuitive language that is easy to learn. Swift code is safe, precise and runs very fast.

Swift follows Objective-C runtime library which allows C, Objective-C, C++ and Swift code to run within one program. Swift is built with open source LLVM compiler and included in Xcode since version 6.
