"Hello, World!" in 10 Different Programming Languages: A Classic Introduction to Coding

on

One of the most common ways to dive into the world of programming is through the classic "Hello, World!" program. It's a simple task—printing out the phrase "Hello, World!" to the screen—but it serves as an introduction to the basic syntax and structure of a programming language. It’s the first step most developers take when they start learning a new language. Today, I’m going to walk you through how this program is written in ten different programming languages, ranging from beginner-friendly ones to more complex systems. Let's get started!


1. Python

Python is one of the most popular programming languages, widely known for its simplicity and readability. It’s often recommended as the first language for beginners because of its clean syntax.

python

print("Hello, World!")

In Python, you simply use the print() function to output text. There's no need for a semicolon at the end of the line or any special setup. I remember when I first encountered Python, it felt almost like writing plain English, which made it much easier to grasp as a beginner.

2. JavaScript

JavaScript is the language of the web. If you’re looking to get into web development, JavaScript is essential. It’s primarily used for creating interactive web pages.

javascript

console.log("Hello, World!");

In JavaScript, the console.log() function prints "Hello, World!" to the browser’s console. When I was learning JavaScript, it amazed me how it could manipulate web pages in real-time. This little "Hello, World!" output may seem trivial, but it’s your first interaction with the world of dynamic web development.

3. Java

Java is a widely-used, object-oriented programming language. It’s known for its portability, meaning Java programs can run on any device that supports the Java Runtime Environment (JRE).

java

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

Writing "Hello, World!" in Java is a bit more involved than in Python or JavaScript. You need to define a class and a main method, which serves as the entry point of the program. When I first learned Java, I was introduced to concepts like classes and objects, which laid the groundwork for understanding object-oriented programming (OOP).

4. C

C is a foundational programming language, often used in systems programming due to its efficiency and control over hardware. Although it can be more complex to learn, mastering C gives you a deep understanding of how computers work.

c

#include <stdio.h>

int main() {
    printf("Hello, World!\n");
    return 0;
}

In C, you need to include the stdio.h library to use the printf() function, which is used to output text. The \n adds a newline character after the output. C was one of the languages that gave me a deeper appreciation for memory management and how a computer truly processes commands.

5. C++

C++ builds on the foundation of C but adds support for object-oriented programming, among other features. If you're learning C++, you'll encounter a lot of the same syntax as C, but with more powerful tools at your disposal.

cpp

#include <iostream>

int main() {
    std::cout << "Hello, World!" << std::endl;
    return 0;
}

Here, instead of printf(), we use the std::cout object to print text. When I transitioned from C to C++, it was like unlocking new levels in a game. C++ gave me more tools to work with, like classes and templates, while still retaining the power and speed of C.

6. Ruby

Ruby is known for its elegant and expressive syntax. It’s widely used for web development, particularly with the Ruby on Rails framework. Ruby’s philosophy is focused on making programming more enjoyable.

ruby

puts "Hello, World!"

In Ruby, we use puts to print text, and just like in Python, there’s no need for semicolons. When I first started with Ruby, I was impressed by how intuitive it was. The language encourages you to write code that feels almost like writing sentences, which makes it a joy to use.

7. PHP

PHP is a server-side scripting language primarily used for web development. It’s commonly embedded within HTML to build dynamic web pages.

php

<?php
echo "Hello, World!";
?>

In PHP, echo is used to output text. One of the things I found fascinating about PHP is how seamlessly it can be integrated into HTML. This simple "Hello, World!" program may seem basic, but it’s a stepping stone toward building dynamic websites and handling server-side logic.

8. Swift

Swift is Apple’s programming language for iOS and macOS development. It’s designed to be powerful and intuitive, making it easier for developers to write safe and concise code.

swift

print("Hello, World!")

Swift’s syntax is clean and easy to read. The print() function is used to output text, similar to Python. When I first tried Swift, I loved how it took some of the best aspects of modern programming languages and blended them with Apple’s robust ecosystem. It felt like I was building apps at lightning speed.

9. Go (Golang)

Go, often referred to as Golang, is a statically typed language developed by Google. It’s known for its simplicity, performance, and concurrency features, making it a great choice for systems programming and large-scale web applications.

go

package main

import "fmt"

func main() {
    fmt.Println("Hello, World!")
}

In Go, you need to define the main package and import the fmt package to use the Println() function. What I love about Go is its focus on simplicity without sacrificing performance. It was refreshing to learn a language that prioritizes speed and efficiency, which is especially useful when building scalable systems.

10. Rust

Rust is a systems programming language that prioritizes safety and performance, particularly in memory management. It’s gaining popularity for its ability to prevent common programming errors such as null pointer dereferencing and data races.

rust

fn main() {
    println!("Hello, World!");
}

In Rust, the println!() macro is used to print text to the console. When I first started with Rust, I was blown away by its focus on safety without sacrificing performance. It’s a language that gives you low-level control like C, but with modern tools to avoid common pitfalls.

Conclusion

Writing "Hello, World!" in different programming languages provides a fascinating look into the syntax and structure of each language. From the simplicity of Python to the efficiency of C and Rust, every language offers unique features and ways of thinking about problems.

Here’s a quick summary of what we’ve covered:

  1. Python: Simple, beginner-friendly.
  2. JavaScript: The language of the web.
  3. Java: Object-oriented and versatile.
  4. C: A foundational language for systems programming.
  5. C++: Adds object-oriented features to C.
  6. Ruby: Elegant and expressive.
  7. PHP: Popular for web development.
  8. Swift: Ideal for Apple app development.
  9. Go: Efficient and powerful, great for scalable systems.
  10. Rust: Safe and performant, especially for systems programming.

Each language opens up a new world of possibilities. Whether you’re aiming to build websites, develop mobile apps, or write systems code, there’s a language tailored for the job. Learning to write "Hello, World!" in these ten languages isn’t just about printing text—it’s about understanding the basic structure and syntax that will serve as a foundation for solving real-world problems.

No matter where you are on your programming journey, the "Hello, World!" program is always a reminder of where it all begins. Every time I start with a new language, printing that simple phrase feels like the first step into something new and exciting.
