MonkeyLang Interpreter

This project is part of the book "Writting and interpreter in Go". This repository keeps track of my progress through the book

Language Features

• C-like syntax
• Variable bindings
• Integers and booleans
• Arithmetic expressions
• Built-in functions
• First-class and higher-order functions
• Closures
• String data structure
• Array data structure
• Hash data structure

Language Syntax

Assignment:

let age = 10 * (20/2);
let myArray = [1, 2, 3, 4, 5];
let someHash = {"name": "Felix", "age": 100}

Accessing Elements:

myArray[0]
someHash["name"]

Functions:

let add = fn(a,b) { return a + b; };
let add = fn(a,b) { a + b; }

add(1,2);

Note: Monkey also supports higher order functions(functions as arguments)
