JavaScript: async/await

The async and await keywords make it easier to work with asynchronous code. async functions return a Promise, and await pauses the execution until the Promise is resolved.

An async function always returns a Promise. You can use .then() to handle the result.

You can also define async functions using function expressions.

async can also be used with arrow functions.

If you don’t use await, the code runs like a normal synchronous function.

await pauses the function until the awaited expression is resolved. It only works inside async functions.

This shows how async/await pauses execution during API calls using fetch().

You can combine async/await with .then() and .catch() to handle responses and errors.
