How does try/catch work with async/await?

1. Definition

In Node.js, try/catch is used with async/await to handle errors in asynchronous code. It works similar to synchronous error handling, making async code easier to read and manage.

2. How it Works

await pauses execution until promise resolves
If promise rejects → control goes to catch
Errors are handled like synchronous code

3. Example

const fs = require("fs").promises;

async function readFile() {
  try {
    const data = await fs.readFile("file.txt", "utf8");
    console.log(data);
  } catch (err) {
    console.error("Error:", err.message);
  }
}

readFile();

4. Without try/catch (Problem)

async function readFile() {
  const data = await fs.readFile("file.txt", "utf8");
  console.log(data);
}

// ❌ If error occurs → Unhandled Promise Rejection

5. Advantages

Clean and readable code
Handles async errors like sync code
Prevents crashes
Better debugging

6. Best Practices

Always wrap await inside try/catch
Handle specific errors when possible
Avoid empty catch blocks
