Hello, World! in 50 Programming Languages — How Many Can You Recognize?

#programming #discuss #beginners #learning

When learning a new programming language, developers frequently write “Hello, World!” as their first program. It provides a straightforward method of familiarising oneself with syntax, fundamental output functions, and compilation or interpretation procedures.

We’ll look at how to print “Hello, World!” in 50 different programming languages in this post.

This highlights the similarities of programming fundamentals while showcasing the diversity and syntactic variances among programming languages.

Here are the first 10 “Hello, World!” examples with explanations:

1. Python

Python is a popular high-level programming language known for its simplicity and readability.

print("Hello, World!")
Enter fullscreen mode Exit fullscreen mode

This program prints “Hello, World!” to the console using the built-in print() function.

2. Java

Java is a widely-used object-oriented programming language.

public class Main {
    public static void main(String[] args) {
        System.out.println("Hello, World!");
    }

If you have doubt in which is the best programming language to learn, the below video might help 👇

Although the syntax, structure, and functions of programming languages vary, they all essentially aim to enable us to convey commands to a machine. Writing a rudimentary “Hello, World!” program is frequently the first step in learning a new language since it gives you a better understanding of its syntax, execution mechanism, and fundamental features.

Examining “Hello, World!” in 50 different languages demonstrates the variety of programming paradigms, including declarative, procedural, object-oriented, and functional.

Learning new languages broadens your problem-solving abilities and enhances your comprehension of software development, regardless of your level of experience. The next stage is to move past “Hello, World!” and become proficient in the language of your choosing by experimenting with variables, loops, functions, and more.
