In this JavaScript Async Await tutorial, we understand the concept of asynchronous programming a bit more closely. These programming functions make the usage of promises a lot easier. The tutorial on JavaScript Async await explains the functionalities of Async Await with the help of a demo.

The following are the topics covered in this JavaScript Async Await tutorial:
0:00 Introduction to JAvaScript Async Await
00:34 Synchronous programming
01:12 Asynchronous programming
02:12 JavaScript Async functions
02:59 JavaScript Async Await demo

What is Synchronous Programming?
Synchronous programming includes the sequential execution of functions and processes. If a particular function needs a resource, execution stops until the currently executing function fetches the resource and finishes its process. Although this ensures that the execution is error-free, it’s time-consuming and doesn’t use the system to its full potential. Asynchronous programming solves these issues.

What is Asynchronous Programming?
Asynchronous programming, on the other hand, ensures that the execution does not stop if a function is performing other operations. Instead, the execution continues normally until the function is called back again. To facilitate this, concepts like Callbacks, Promises, and Async/await are used.

JavaScript Async Await Functions
JavaScript Async await are built on promises. The keyword “async” accompanies the function, indicating that it returns a promise. Within this function, the await keyword is applied to the promise being returned. The await keyword ensures that the function waits for the promise to resolve. On the surface, the execution looks synchronous, but it is asynchronous. The function’s execution is blocked at the await keyword’s placement in the coding. Async functions make the code more readable and are easier to handle than promises.

The logic of the example is not consistent. In the example, If the score is greater than 50, they pass, else they get an A. The logic should be that they fail, not get an A
