海外TECH	DEV Community	Callback, Callback Hell, Promise Chaining and Async/Await in JavaScript	https://dev.to/shameel/callback-callback-hell-promise-chaining-and-asyncawait-in-javascript-120i	Callback Callback Hell Promise Chaining and Async Await in JavaScriptThese concepts are must know kind of thing if you work with JavaScript TypeScript or its libraries and frameworks and are often asked in technical interviews We are going to be discussing CallbackCallback HellPromise overview Promise ChainingAsync Await CallbackBefore understanding about callback hell we first need to know what the hell is callback in JavaScript JavaScript deals functions as first class citizens i e function can be passed as an argument to another function as well as a function can be returned from another function A callback in JavaScript is a function that is passed into another function as an argument Callback has nothing to do with the asynchronous behavior of JavaScript A callback is simply a function that is passed as an argument to another function and is intended to be executed at a later time or after a specific event occurs This event doesn t have to be an asynchronous operation it could be a user action a specific condition being met or any other event you want to handle with a separate function Let s go on and see the examples of callback in context of synchronous and asynchronous behaviour Callback Synchronous Example A function that takes a callback as an argument and invokes itfunction performOperation callback console log Performing the operation callback Define a callback functionfunction callbackFunction console log Callback has been executed Calling the main function with the callbackperformOperation callbackFunction You will se an output like this Performing the operation Callback has been executed Callback Asynchronous Example A function that takes a callback as an argument and invokes itfunction doSomethingAsync callback setTimeout function console log Async operation done callback Define a callback function function callbackFunction console log Callback has been executed Calling the main function with the callback doSomethingAsync callbackFunction You will see output like this Async operation done Callback has been executed Callback HellNow we somewhat understood what the hell is callback let s go on exploring Callback Hell Callback hell is introduced when we have nested functions This is a requirement in almost all real world applications As more nested callbacks are added the code becomes harder to read maintain and reason about This can lead to bugs and difficulties in debugging See for yourself Declaring Functions function asyncFunction callback setTimeout gt console log Async Function Done callback function asyncFunction callback setTimeout gt console log Async Function Done callback function asyncFunction callback setTimeout gt console log Async Function Done callback Calling the code asyncFunction gt asyncFunction gt asyncFunction gt console log All Async Functions Completed As you can see pyramid of doom being formedIf there are more operations to be performed then the pyramid s height will keep increasing and so would be the impact of doom Real world exampleFor example an authenticated user performed some action from the browser which hits an API that involves getting the data from database and sending notification E mail back to the user this could be performed in a series of steps one after another Receives request from the user Authenticate the user Check authorization level of user to perform an action Perform the action Send Notification E mail Send response back to the user browser So it could be something like Step Receives request from the userapp post performAction req res gt Step Authenticate the user authenticateUser req body username req body password authError isAuthenticated gt if authError res status send Authentication failed else if isAuthenticated res status send User not authenticated else Step Check authorization level of user checkAuthorization req body username authLevelError isAuthorized gt if authLevelError res status send Authorization check failed else if isAuthorized res status send User not authorized else Step Perform the action performAction req body actionData actionError result gt if actionError res status send Action failed else Step Send Notification E mail sendNotificationEmail req body username emailError gt if emailError console error Failed to send notification email Step Send response back to the user browser res status send Action performed successfully You can see that the pyramid of doom has doomed us in this example What happens if there are sockets involved in which a notification is sent in real time The data to be sent via socket and stuff like that All within one singular operation Then the doom will keep on increasing and it will be a living hell for developers to maintain the code change business logic and God forbid to debug it if any error occurs Promises to the rescueECMAScript also known as ES introduced the JavaScript Promise object Promise in JavaScript is a detailed concept to be studied but for short terms you can think of it as a really good way to deal with asynchronous behavior of JavaScript It has three states PendingResolvedRejectedWhen an action is being performed then the state is in pending if the action is successful then the result is resolved otherwise the result is rejected JavaScript promises us that it will return us something after a certain duration of time whenever the asynchronous task has been completed You can see a short example here function asyncFunction return new Promise resolve gt setTimeout gt console log Async Function Done resolve asyncFunction then gt console log Async operation performed The result would be like this Async Function DoneAsync operation performed Promise ChainingOkay that s great Promises introduced But how does it deal with our problem of callback hell The answer is with Promise chaining Let s modify our simple example from before Function declarationfunction asyncFunction return new Promise resolve gt setTimeout gt console log Async Function Done resolve function asyncFunction return new Promise resolve gt setTimeout gt console log Async Function Done resolve function asyncFunction return new Promise resolve gt setTimeout gt console log Async Function Done resolve Our functions are now returning promises Let s see how we execute them now asyncFunction then gt asyncFunction then gt asyncFunction then gt console log All Async Functions Completed catch error gt console error An error occurred error We will see the result like this Async Function DoneAsync Function DoneAsync Function DoneAll Async Functions CompletedThis increased readability but for inclusion of async await with the work of promises has given much better working environment to the codebase For the real world pseudo example we discussed earlier that can also be re written like this for promise chaining Step Receives request from the userapp post performAction req res gt authenticateUserPromise req body username req body password then isAuthenticated gt if isAuthenticated res status send Authentication failed return Promise reject Step Check authorization level of user return checkAuthorizationPromise req body username then isAuthorized gt if isAuthorized res status send User not authorized return Promise reject Step Perform the action return performActionPromise req body actionData then gt Step Send Notification E mail return sendNotificationEmailPromise req body username then gt Step Send response back to the user browser res status send Action performed successfully catch error gt console error An error occurred error res status send An error occurred Async AwaitECMAScript introduced the JavaScript keywords async and await The purpose was to further simplify the use of promises in JavaScript world async keyword is written before the function and await is written before the function which executes asynchronous operation We can execute the same code like this async function runAsyncFunctions try await asyncFunction await asyncFunction await asyncFunction console log All Async Functions Completed catch error console error An error occurred error runAsyncFunctions Or much shorter way with IIFE Immediately Invoked Function Execution async gt await asyncFunction await asyncFunction await asyncFunction console log All Async Functions Completed The real world example can be used with promises and async await like this Step Receives request from the userapp post performAction async req res gt try Step Authenticate the user const isAuthenticated await authenticateUserPromise req body username req body password if isAuthenticated res status send Authentication failed return Step Check authorization level of user const isAuthorized await checkAuthorizationPromise req body username if isAuthorized res status send User not authorized return Step Perform the action const result await performActionPromise req body actionData Step Send Notification E mail await sendNotificationEmailPromise req body username Step Send response back to the user browser res status send Action performed successfully catch error console error An error occurred error res status send An error occurred ConclusionCallback functions can be used to perform asynchronous operation Callback hell is introduced with nested operations Promise chaining solves callback hell Async Await further improves the solution I hope that helps Let me know if there was any confusion anywhere in the article or the mistake that you think should be rectified Follow me
