Async Map

Implement an async version of Array.map that processes items with an async function.

Requirements:

• Implement asyncMap that takes an array and async function
• Process all items and return results in original order
• All async operations should run in parallel
• Return a Promise that resolves with the array of results

Example:

const numbers = [1, 2, 3, 4];
const double = async (n) => n * 2;

asyncMap(numbers, double).then(result => {
  console.log(result); // [2, 4, 6, 8]
});
