Hey World, hello!

This is Hey World, hello! in all languages I can remember to have built working software, either for production, prototyping or academic projects.

Javascript and Typescript

Starting with Javascript, I've spent about 7 years working with it and I still got mixed feelings. The language itself is far from being perfect but it is improving quite well since ES6 and Typescript releases:

console.log('Hey World, hello!')

PHP

The first language I used for dynamic web pages, it was on version 4 back then. Later I've used it for production level applications using Yii and CodeIgniter MVC frameworks.

Copycopy code to clipboard
<?php echo "Hey World, hello!"; ?>

Bash

UNIX shell script is such a powerful tool, invest time improving bash skills, it will worth it.

Copycopy code to clipboard
#!/bin/bash
echo "Hey World, hello!"

Lua

Means Moon in Portuguese. A powerful, lightweight scripting language widely used in gaming platforms. I've used it to develop a mobile game using Corona SDK (2D game engine):

Copycopy code to clipboard
print("Hey World, hello!")

BrightScript

Proprietary scripting language to build channels for Roku TV streaming platforms. You need to build nearly everything from scratch as community (and open-source libs) basically don't exist.

? "Hey World, hello!"

C

I used C in academic projects for example to build a simple chat with Socket-based IPC (InterProcess Communication)

Copycopy code to clipboard
printf("Hey %s, %s!", "World", "hello");

Java

Everybody knows a little bit of JAVA, right? I'm more into functional programming now although well designed OOP application has its own place in my heart.

Copycopy code to clipboard
System.out.println("Hey World, hello!");

C#

Only used for academic projects in a very similar way to Java. Used to demonstrate design patterns and good practises:

Copycopy code to clipboard
Console.WriteLine("Hey World, hello!");

Assembly (8051 Architecture)

This is the funny on.. During my academic path I had to code running programs for AT80S51 microcontroller, you need to be careful or you might mistake a R0 by RO as I did (and took me nearly 3 days to figure it out). Obviously I can't code it anymore but here is an example I took from here:

Copycopy code to clipboard
LCALL INIT_LCD
LCALL CLEAR_LCD
MOV A,#'H'
LCALL WRITE_TEXT
MOV A,#'E'
LCALL WRITE_TEXT
MOV A,#'Y'
LCALL WRITE_TEXT
...

Wolfram Mathematica

Similar to MatLab, this software is very powerful when it comes to applied science and mathematics. I've used it only on academic environment.

Print["Hey World, hello!"]

VisualBasic

This is a classic! Used to play with it when in high school to build simple UI apps and impress my friends :D

Copycopy code to clipboard
MsgBox "Hey World, hello!"

I've played with other languages like Go, Dart and Rust but never built something with it.
