Fetch API & Handling JSON Responses

What advanced pattern is implemented in this code?

async function fetchWithRetry(url, retries = 3) {
  for (let i = 0; i < retries; i++) {
    try {
      const response = await fetch(url);
      if (!response.ok) throw new Error(`HTTP error! status: ${response.status}`);
      return await response.json();
    } catch (error) {
      if (i === retries - 1) throw error;
      await new Promise(r => setTimeout(r, Math.pow(2, i) * 1000));
    }
  }
}

Simple error handling
Basic request validation
Exponential backoff retry
This implements exponential backoff retry: 1) Automatically retries failed requests, 2) Increases delay exponentially between retries, 3) Handles both network and HTTP errors, 4) Prevents overwhelming servers during issues, 5) Improves reliability of API interactions, 6) Common pattern for handling transient failures.
Request queuing
