How to Write Hello World in Every Programming Language

I want to share this great resource that shares how to write Hello, World code in any programming language. The site has been around for a long time and is a pretty cool way to explore other languages that you may have never tried before, or maybe never even heard of. In fact, there is a high chance that you have never heard of many of these languages.

Check out the Hello World Collection to learn how to program a Hello, World program/app/script in any programming language.

PHP programming is a very popular choice and programming a Hello World PHP script is extremely simple. You can literally just use <?php echo "hello world"; ?> in a PHP file and your page will say "hello world" or whatever other value you use with echo. I think it is great how programming languages have progressed throughout the years. This PHP tutorial for beginners is a great example of how you can create a Hello World PHP script in so many different ways. From a standard PHP echo to the less ideal print() function/language construct, there is much to learn with PHP string concatenation, array key values, and HTML/PHP views. Honestly, you can really learn a lot just by exploring the various different things you can do with the very basics of a beginner PHP tutorial.

Did you know that many foreign programmers end up learning English because so much of the core code is written in English? Of course, there are translations of many popular programming languages so people from all over the world can get started, but this is not the case for all languages. In fact, many schools, teachers, mentors, and online classes actually encourage non-English speakers to learn the bare minimum English (or more) so that their code is compatible with English speaking/writing companies overseas.

The Korean Aheui programming language is interesting because it's written in a totally different language (Korean) unlike many programming languages that are in English! There are of course other languages that were started in foreign languages, and many of these have never been translated to English even though they can run on any computer set up to interpret them.
Aheui Hello, World Code:
Code:
밤밣따빠밣밟따뿌
빠맣파빨받밤뚜뭏
돋밬탕빠맣붏두붇
볻뫃박발뚷투뭏붖
뫃도뫃희멓뭏뭏붘
뫃봌토범더벌뿌뚜
뽑뽀멓멓더벓뻐뚠
뽀덩벐멓뻐덕더벅
This is an example of a really long code block. This programming language is designed for Data General Nova, a series of 16-bit computers back in the 1970's. I would love to think that if I was simply born earlier that I could have made one of the first computers or operating systems... Perhaps many of you have thought the same. Let this be an example of how much more complicated programming can be when you don't have an interpreter to handle your code.
Code:
                        .TITL HELLO
02                      ; "HELLO, WORLD" FOR NOVA RUNNING RDOS
03                      ; USES PCHAR SYSTEM CALL

Feel free to share any interesting Hello World code you see on the site or discuss in general :) !

You know, I never actually knew that there were more than 300-500+ programming-languages. Makes you wonder how many more languages will show up. Then we'll have more Hello Worlds go to by.
