What is a thunk function

What is a thunk function?

A thunk function is a function that wraps another function or expression, typically used to delay the execution of the original function. It is often used in functional programming to manage side effects or control execution order.

Example:

const add = (a, b) => a + b;
const thunk = (a, b) => () => add(a, b);
const result = thunk(2, 3)();  // Output: 5
