Fun Interpreter

This interpreter was derived from the book Writing an Interpreter in Go which I followed to get the basic structure for lexical analysis & tokenization, parsing, and evaluation.

Language Features

The language that I built the interpreter on is a made-up one. However, it has the features of most modern programming languages today with C-like syntax:

• variable bindings
• integers & booleans
• arithmetic expressions
• built-in functions
• first-class & higher-order functions
• closures
• string data structure
• array data structure
• hash data structure

Sample Code

let fibonacci = fn(x) {
  if (x == 0) {
    return 0;
  } else {
    if (x == 1) {
      return 1;
    } else {
      fibonacci(x - 1) + fibonacci(x - 2);
    }
  }
};
