  3. 💡 Conclusion

When using async functions with await and setTimeout, it's common to encounter issues due to the way these concepts interact. The problem lies in the fact that async functions are designed to handle asynchronous operations, whereas setTimeout is a synchronous function that can block the execution of the code.

🔍 Why This Happens

  • Async functions use await to pause the execution of the code until an asynchronous operation completes. When setTimeout is used alongside async functions, it can cause issues because setTimeout is executed synchronously and can block the execution of the code.

✅ Best Solutions to Fix It

Method 1: Using async/await with setTimeout

  1. Step 1: Replace setTimeout with an async function call.

Method 2: Using Promise.then

  1. Step 1: Use a promise to handle the setTimeout function.

💡 Conclusion

By understanding how async functions and setTimeout interact, you can write more efficient and effective code. Remember to use async/await or Promise.then when working with asynchronous operations.
