  8. JavaScript Async functions (async/await) Async and await are built on top of promises to express asynchronous actions Inside the function, the await keyword can be applied to any Promise, which will defer the execution until the promise resolves Functions with the async keyword return a Promise

  9. JavaScript Async functions (async/await) Functions with the keyword async can perform asynchronous actions but still look synchronous The await method is used to wait for the promise to either get fulfilled or rejected The await method blocks the execution of the async function at the place it is located in

  10. JavaScript Async functions (async/await) Async functions make the code more readable and are easier to handle than promises

  11. JavaScript Async functions (async/await) General Syntax Async function function_name(){ await some_promise() }
