Hello, World 

Every language greets the world the same way first. The phrase traces back to Brian Kernighan's 1972 tutorial for the B language at Bell Labs, then rode printf("hello, world\n"); into fame through Kernighan & Ritchie's C book in 1978 — and it's been the first line written in a new language ever since.

#include <stdio.h>
int main() { printf("hello, world\n"); }

print("Hello, World!")

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

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

(format t "~a, ~a!~%" "Hello" "World")
