Let’s quickly understand what async/await functions are and how they are used in JavaScript. Async stands for asynchronous, and it permits the execution of a function without blocking the flow of the program. It uses promises, which are nothing but values that get fulfilled in the future. For example, let us consider a case where a third-party API is called from within a function as a promise. If the call and its response are successful, then the promise is fulfilled, but if there is a network failure, then it is rejected. We could define specific behavior for each of these cases.
