Question
Generate hello world on all programming languages
Answer
While it is impossible to list "all" programming languages (there are thousands of them, and new ones are created every year), I have compiled a comprehensive list of **"Hello, World!"** programs across the most popular, historically significant, and interesting programming languages, categorized for your convenience.
### 🌟 The Modern Classics
**Python**
```python
print("Hello, World!")
```

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

```typescript
console.log("Hello, World!");
```
### 👴 The C Family
**C**
```c
#include <stdio.h>

std::cout << "Hello, World!" << std::endl;
return 0;
}
```

mov ebx, 1 ; stdout
mov ecx, msg
mov edx, 13
int 0x80
mov eax, 1 ; sys_exit
xor ebx, ebx
int 0x80
section .data
msg: db "Hello, World!", 10
```
### 🤪 Esoteric & Joke Languages
