1. Memoization

Implement a memoize function that caches the results of function calls to improve performance.

Requirements

1. Basic Functionality

• Accept a function fn
• Return a memoized version of the function
• Cache function results based on arguments
• Return cached result if arguments match
• Call original function if not cached

Example Usage

// Example: Expensive computation
const expensiveFn = (n) => {
  console.log('Computing...');
  return n * 2;
};

const memoized = memoize(expensiveFn);

memoized(5); // Logs: Computing..., returns 10
memoized(5); // Returns 10 (from cache, no log)
memoized(6); // Logs: Computing..., returns 12
