A fictional programming language
Thnad is a tiny programming language with so few features that it is not useful for anything at all--except showing how to write a compiler in half an hour.
Here's the factorial function in Thnad:
function factorial(n) {
if(eq(n, 1)) {
1
} else {
times(n, factorial(minus(n, 1)))
}
}
print(factorial(4))
The language has only the following dubious features:
- Integer literals
- Functions
- Conditionals (with a required "else")
That's it! Math and comparison are function calls. IO (or rather just O, as there is no input) is a simple print function.
