convert asynchronous to synchronous function

 To convert an asynchronous function to a synchronous function, you'll need to remove the asynchronous behavior and ensure that the function executes synchronously, blocking the execution until it completes. Here's a general approach to achieving this conversion:

1. Identify the asynchronous function: Identify the function that you want to convert from asynchronous to synchronous. It might have the async keyword in its definition or return a Promise object.

2. Remove the async keyword: Remove the async keyword from the function declaration, making it a regular synchronous function.

3. Handle Promise resolution: If the asynchronous function returns a Promise, you'll need to handle the resolution of the Promise and obtain the result synchronously. You can use techniques like Promise.await() or Promise.then() to wait for the Promise to resolve and obtain the result.

// Asynchronous function
async function asynchronousFunction() {
  return new Promise((resolve) => {
    setTimeout(() => {
      resolve('Async result');
    }, 2000);
  });
}

// Conversion to synchronous function
function synchronousFunction() {
  // Create a Promise wrapper around the asynchronous function
  const promiseWrapper = new Promise((resolve) => {
    resolve(asynchronousFunction());
  });

  // Wait for the Promise to resolve and obtain the result synchronously
  const result = Promise.await(promiseWrapper);
  
  // Return the result synchronously
  return result;
}

// Usage of the synchronous function
console.log(synchronousFunction()); // Output: Async result

sIn this example, the asynchronousFunction() is converted to the synchronousFunction(). The asynchronous function returns a Promise that resolves after a timeout of 2 seconds. By using Promise.await() (a fictional method for illustrative purposes), we wait for the Promise to resolve and obtain the result synchronously in the synchronousFunction().

Keep in mind that converting an asynchronous function to synchronous may introduce blocking behavior, which can lead to decreased performance and responsiveness, especially in scenarios where asynchronous execution is preferred. Therefore, it's generally recommended to use asynchronous functions when possible, leveraging non-blocking execution and callbacks, Promises, or async/await
