Programming languages ​​2020: which one is better to choose

Let’s take a look at the best programming languages ​​in 2020, the reasons for choosing and how to implement “Hello World” in each of them.

List of the best languages

If you don’t want to watch the entire article, here are the top 10 languages ​​for you this year:

  1. Python – programming language for artificial intelligence and machine learning
  2. Java – the best programming language for server-side development and backend
  3. JavaScript – popular choice for client side scripting
  4. C ++ – the best general purpose programming language
  5. C – the most reliable language today
  6. Ruby – Proven Choice for Data Science and Web Development
  7. C # – powerful object-oriented language from Microsoft
  8. Swift – the most efficient programming language for iOS development
  9. PHP – the best server-side web development language
  10. Golang – a scalable system programming language from Google

Now that we are done with a quick list for the lazy and they are out of us, let’s move on to each language.

1. Python

The official site is Python.

Developed in the 1990s by Guido van Rossum, Python is perhaps the only language everyone loves.

The language is distinguished by an easy learning process, and the ability to function on an industrial scale development.

It has simple and elegant syntax along with an active community. Python is widely used in the fields of artificial intelligence, machine learning, data science, and web development.

print("Hello World")

2. Java

Official site – Java.

Java was developed with the goal of creating a simple, object-oriented, interpreted programming language.

It was supposed to act as an alternative to C ++, which was widely used in business applications in the 90s. But over time, Java has vastly surpassed C ++ in popularity due to its lower learning curve and high prevalence of Java code.

Java with the Java Virtual Machine is a platform independent language. This makes it the most popular enterprise programming language.

Java is widely used in the fields of application development, big data, and web development.

Snippet of “Hello World” Java code:

public class HelloWorld
 public static void main(String[] args)
  System.out.println("Hello World");

3. Javascript

JavaScript was developed by Brendan Eich for Netscape during the first browser war.

Despite its poor design and lack of features, JavaScript has become a dynamic high-level programming language.

Thanks to the breakthroughs in Node.js and AngularJS, JavaScript has become the undisputed leader in browser programming today.

JS offers event-driven programming that supports the requirements of applications that rely heavily on I / O tasks. JavaScript is widely used in the fields of web development, back-end, and serverless computing.

 alert('Hello World');

4. C ++

Official site – C ++.

Designed as an extension of C, C ++ was originally aimed at creating a language that could bring object-oriented capabilities to the popular C language.

Over time, it developed into a general-purpose language with low-level memory access and complete hardware control. C ++ is a language that probably offers a wide variety of features, making it really difficult to learn.

C ++ can run on any platform and use any hardware. It is a really fast programming language which makes it popular for use in resource constrained systems. C ++ is widely used in systems programming, game development, IoT, and embedded systems.

Snippet of “Hello world” code in C ++:

using namespace std;
void main() {
    cout<<"Hello World";


Developed in the 1960s, C was created with one basic requirement: to be a general-purpose language that could make efficient use of system resources. This was the time when every byte of memory was needed.

Since C ++ was based on C, they share common features such as low-level memory access and complete control over hardware.

C is platform dependent and difficult to learn. But even today it is one of the most popular programming languages. It is also a language that has inspired many others such as Ruby, C ++, Python, and PHP. C is widely used in the fields of systems programming, game development, IoT, and embedded systems.

void main()
    printf("Hello World");

6. Ruby

The official site is Ruby.

Ruby started out as an object-oriented scripting language. But over time, it evolved into a high-level, interpreted universal programming language.

It has a fairly low barriers to entry with a focus on productivity and developer experience.

It combines some of the best features of all popular programming languages. It is dynamic, functional and concise.

In addition, the language has an active community along with excellent structural support. Ruby is widely used in web development, data analysis, and AI development.

puts "Hello World"

7. C #

Official site – C #.

Microsoft developed C # as a C-like programming language with object-oriented features. This was part of their .NET project. The language was originally seen as a copy of Java. However, future developments have brought a clear, distinct identity to C #.

C # offers a great developer experience. With the support and presence of Microsoft for over two decades, it has a variety of libraries and frameworks.

It is also a platform independent programming language. C # is widely used in systems programming, game development, web development, and application development.

Snippet of “Hello world” code in C #:

namespace HelloWorld
    class Hello
        static void Main(string[] args)
            Console.WriteLine("Hello World");

8. Swift

Official site – Swift.

Swift is Apple’s powerful general-purpose compiled programming language. Developed in the past decade, it has effectively replaced C for software development on both Mac and iOS platforms.

With its concise syntax and focus on developer productivity, the language began to spread to other platforms.

Swift offers great features because it is a modern language, yet fast enough to be comparable to C ++.

Swift is widely used today in iOS app development, systems programming, deep learning, and IoT.

print("Hello World")

9. PHP

Official site – PHP.

Originally developed as a set of Common Gateway Interface (CGI) binaries for developing dynamic web applications, PHP has evolved over the years into a full-fledged programming language.

It has been used to build web applications for over 35 years and there are many platforms available to developers.

Despite its recent decline in popularity, PHP is still one of the most widely used programming languages.

It finds application mainly in the field of server-side and stand-alone web application development, as well as in the development of CMS systems.

echo "Hello World";

10. GoLang

Official site – GoLang.

Developed as Swift in the last decade, Go was created by Google after realizing that existing programming languages ​​weren’t up to the task of efficiently handling their databases.

Go is a language known for its design, simplicity, and ability to tackle the problem of scaling development.

Go is easy to learn and provides an elegant yet powerful option for developers. It is also one of the fastest growing programming languages ​​today.

Go is widely used in systems programming, serverless computing, IoT, and cloud development.

Snippet of “Hello World” code in GoLang:

package main
import "fmt"
func main() 
     fmt.Println("Hello World")

This was a list of the 10 best programming languages ​​for 2020.

But remember – there is no better programming language than the one that suits your needs.
