async main in javascript

To make the entry point of a JavaScript program asynchronous, you can make use of the async keyword in the function signature of the main method, which turns it into an async function. Then, you can use various asynchronous patterns, such as Promises or the newer async/await syntax to perform asynchronous operations.

Here's an example of using the async/await pattern with an async main method:

async function main() {
  try {
    const result = await someAsyncOperation();
    console.log(result);
  } catch (error) {
    console.error(error);
  }
}

main();

In the example above, main() is an asynchronous function that awaits the result of someAsyncOperation(), which could be an HTTP request or any other asynchronous operation. The try...catch block is used to handle any errors that may occur during the execution of the main method. Finally, main() is called at the end to start the program.
