wrap async function in javascript

To wrap an asynchronous function in JavaScript, you can use the async/await syntax or return a Promise from the function.

Using async/await, you can define an asynchronous function with the async keyword and then use the await keyword to wait for the completion of asynchronous operations. Here is an example:

index.tsx
async function getData() {
  const response = await fetch('https://example.com/data');
  const data = await response.json();
  return data;
}

Alternatively, you can return a Promise from the function, which allows you to use the then method to handle the result of the asynchronous operation. Here is an example:

index.tsx
function getData() {
  return fetch('https://example.com/data')
    .then(response => response.json())
    .then(data => data);
}

In both cases, you can call the function and handle the result like this:

index.tsx
getData()
  .then(data => console.log(data))
  .catch(error => console.error(error));
