ThoLangForFun programming language

An effort to implement another programming language for fun

Learn how to implement an intepreter:

• Part 1: High-Level Overview
• Part 2: Implementation

Sample code:

Function & recursion:

let fib = function (n) {
    if (n == 0) {
        return 0;
    }
    if (n == 1) {
        return 1;
    }
    return fib(n - 1) + fib(n - 2);
};

fib(8);

While loop:

let n = 10;
let message = "I am counting ";
while (n > 0) {
    message = message + n + " ";
    n = n - 1;
}
put message;
