海外TECH	DEV Community	Understanding Async/Await in JavaScript	https://dev.to/archyscript/understanding-asyncawait-in-javascript-561d	Understanding Async Await in JavaScriptThe word “async before a function means one simple thing a function always returns a promise The keyword “await makes JavaScript wait until that promise settles and returns its result The async await syntax in JavaScript ES makes it easier to coordinate asynchronous promises An async method runs synchronously until it reaches its first await expression at which point the method is suspended until the awaited task is complete resolved or rejected Async await construct allows us to express logic more precise with excellent readable and maintainable code Basic Format Using regular functionasync function asyncRegularFunction let data await ASYNCHRONOUS OPERATION console log data asyncRegularFunction Using arow functionconst asyncArrowFunction async gt let data await ASYNCHRONOUS OPERATION console log data asyncArrowFunction In each functions above the data variable awaits response from ASYNCHRONOUS OPERATION method What is a promise A Promise is a special JavaScript object it produces a value after an asynchronous async operation completes successfully or an error if it does not complete successfully due to time out network error and so on Promise constructor takes only one argument which is a callback function and that callback function is also known as anonymous function Callback function takes two arguments resolve and rejectPerform operations inside the callback function and if everything went well then call resolve If desired operations do not go well then call reject var myPromise new Promise resolve reject gt const var alien const var alien if var var resolve else reject myPromise then function console log You are an Alien catch function console log Sorry an error occurred expected output Success You are an AlienThe flowchart below further explains the concept of async await syntax To understand how async await promises work in JavaScript I will illustrate it with the simple process of delivering an item to a client from the diagram above To make this process asynchronous every steps must be followed in this order store keeper gets an order check if order is available accepts order package item s delivers item s to the client and receives payment in an instance of payment on delivery In this case it is important that our store keeper follows the above process in that exact order because every process are dependent on the response received from the previous This prevents potential errors during delivery and ensures that clients receive what they have ordered in the correct qualities and quantities with all procedures being followed correctly A more practical exampleA simple function to resolve a Promise after seconds function resolveAfterFiveSeconds return new Promise resolve gt setTimeout gt resolve resolved async function asyncCall console log calling const result await resolveAfterFiveSeconds console log result asyncCall expected output calling immediately resolved after five secondsAlso the code below is a sample of how to fetch todos data from an API jasonplaceholder using asynchronous function await the response and then save it in a todos variableconst API URL let response await fetch API URL let todos await response json console log todos expected output an array of todos from json placeholer Yeah You get the idea This is just an introduction to the async await format of handling promise in JavaScript If you re new to async functions I hope this shed some light on how they work and what they do That ll be it for today In conclusion async await helps fetch data asynchronously from multiple databases or APIs in a certain order and is a special syntax to work with promises in a more comfortable fashion Happy coding Stay creative	2022-08-30 15:28:19
