Async await is a relatively new feature of JavaScript that allows developers to write asynchronous code more easily. Traditionally, asynchronous code has had to be written using callback functions, which can quickly become confusing and difficult to read. With async await, developers can write asynchronous code using the same syntax as they would use for synchronous code, making it much easier to read and understand. In addition, async await can help to improve the performance of asynchronous code by eliminating the need for callback functions. As a result, async await is a valuable tool for any JavaScript developer looking to write better asynchronous code.
What Does Require Do

When a module is loaded using the require() function, the module’s code is executed and the exports object of the module is returned. The require() function can be used to load local files as well as modules installed from npm.
