Promise Retry

Create a function that retries an async operation a specified number of times.

Requirements:

• Implement retry that takes an async function and retry count
• Retry the function if it fails, up to the specified number of times
• If all attempts fail, reject with the last error

Example:

let attempt = 0;
async function unreliableFunction() {
  attempt++;
  if (attempt < 3) throw new Error('Failed');
  return 'Success';
}

retry(unreliableFunction, 3).then(result => {
  console.log(result); // 'Success'
});
