Closures

Closures are functions that captures variables from its surrounding lexical scope, allowing those variables to persist even after the function is executed outside its original context

main.w
let createCounter = (): (): num => {
let var count = 0; // This variable is part of the closure

return () => {
count = count + 1;
return count;
};
};

let counter = createCounter();

log(counter());
log(counter());
log(counter());
