海外TECH	DEV Community	JavaScript Promises	https://dev.to/bolajibolajoko51/javascript-promises-2e8b	JavaScript Promises IntroductionThere are various ways asynchronous operation can be handled or managed major ones include the use of Callbacks Promises and Async Await In this article I will be discussing on how you can use JavaScript Promises to handle an asynchronous operations JavaScript Promises are an important feature in JavaScript that is used to handle asynchronous operations or tasks that will take some time to complete such as network requests database queries or file operations JavaScript Promise is one of the best approaches used to handle asynchronous operations in modern JavaScript development because it improves error handling flow control and readability What is JavaScript PromiseAnalogy Let s say your friend has promised to take you out for dinner on a weekend for the way he spoke to you at work He arranged the venue and time for meetup There are two things that might happen for the dinner to hold either your friend makes it to the venue by alerting you or your friend sends you a message that he couldn t make it with reasons JavaScript Promise is similar to this scenario JavaScript Promise is an object that represents the completion or settlement of an asynchronous task Creating PromiseTo create a promise object you can use the constructor syntax const myPromise new Promise resolve reject some operation The callback function passed into the constructor is called an executor which is typically used to perform the asynchronous operation The executor function has two callback functions as the argument the resolve and reject callback functions which are provided by JavaScript The resolve and reject are built in functions provided by JavaScript when creating a Promise If an asynchronous operation runs successfully the executor will call the resolve method and return a value In case the asynchronous task encounters an issue error the executor function will call the reject method and return an error with a reason The Promise object returned by the constructor has two internal properties state and result When a new promise is created its state is pending with a result of undefined When the asynchronous operation is successful the state is changed to fulfilled with a result of value and when an error is encountered the state is changed to rejected with a result of error A promise can only move from a pending state to either being fulfilled or rejected Once a promise is fulfilled or rejected it cannot go back to another state If a promise reaches a fulfilled or rejected state the asynchronous operation is said to be resolved Let s look at a simple example to show the state and result properties of a Promise object const counter true const myPromise new Promise resolve reject gt using setTimeout as an async operation setTimeout gt if counter resolve Counting else reject new Error Can t Count console log myPromise OutputThis loads after three seconds Changing the counter value to falseconst counter false Output Promise MethodsMost of the time you won t be using the resolve and reject methods to handle asynchronous task JavaScript provides some Promise methods you can use to handle the resolving and rejection of operations We will be taking a look at some of the most important fundamental Promise methods JavaScript provides in the subsequent section of this article such as then catch and finally then then method is one of the core methods of Promise object It specify what should be done when an asynchronous task succeeds fulfilled or fails rejected The main purpose of then is to attach the rejection and fulfilment handlers to a Promise Its takes two callback methods one for fulfilment and the other one for rejection Syntaxpromise then onFulfilled onRejected onFulfilled this is a function that runs when the promise is resolved and returns a result onRejected this is a function that runs when the promise is rejected and returns a reason for the rejection then will call the onFulfilled if the Promise is resolved successfully or the then will call the onRejected if the Promise is rejected Resolving Promiseconst pResolved new Promise resolve reject gt setTimeout gt resolve Successful pResolved then result gt console log result error gt console log error Output Successful Rejecting Promiseconst pRejected new Promise resolve reject gt setTimeout gt reject Error pRejected then result gt console log result error gt console log error Output ErrorIn the example above the resolve in the setTimeout signifies that the Promise is resolved and will call the necessary argument in the then which is onFulfiled the first argument in the then method In the second part of the code the reject method in the setTimeout method signifies that the promise is rejected thereby calling the second argument in the then method which is onRejected The then method can accepts either the onFulfiled or onRejected Its depend on which promise state we are more interested in Putting it together Now let s put what we ve been discussing into practice by writing some code You will be building an even numbers generator system The system will raise an error when encountering an odd number function getEven const myPromise new Promise resolve reject gt setTimeout gt const rand Math floor Math random if rand resolve Even Number rand else reject new Error Invalid rand myPromise then result gt console log result error gt console log error setInterval getEven Output The code example demonstrates the creation of a getEven function that generates random even numbers asynchronously It utilizes Promises setTimeout to simulate the asynchronous behavior The Math random in the code is used to generate numbers The then method handles the resolving or rejection of the Promise allowing for the logging of valid even numbers or error messages The function is executed every two seconds using setInterval Key takeaway from using the then method the then help us to resolve or reject an asynchronous task catch Handling Promise rejection can be done in different ways One approach is to use the then method s second argument onRejected to handle errors Another option is to use the catch method which can be chained to the Promise object The catch method accepts a callback function to handle the error Syntaxpromise catch callback error const run false const myPromise new Promise resolve reject gt setTimeout gt if run resolve Running else reject new Error Error myPromise catch error gt console log error Output ErrorIn the example the else statement is executed thereby executing the catch method handler on the Promise object the Promise failed and the reason for it failure is stated If the run variable value is changed to true the if statement will be executed and the promise will be resolve which will make the catch handler not to be executed The catch handler will only be executed if the Promise is rejected or failed finally Yes finally but that s not the end of this article we still have to clean up our code mess and discuss some few concepts Let s do some cleanup using finally method We might want to execute some functions whether the Promise gets resolved or not This is where finally method comes into play The finally method of a Promise object assigns a function to be called when a Promise is settled either fulfilled or rejected The finally method is primarily used to ensure the execution of code that should always run regardless of the result Syntaxpromise finally doSomething If a finally handler return something it will be ignored const counter true const myPromise new Promise resolve reject gt setTimeout gt if counter resolve Completed else reject Failed myPromise then result gt console log result finally gt console log Do Something Output Completed Output Do Something In the example above the Promise is resolved and the finally handler is attached to then handler and the finally gets executed The process of attaching a Promise handler with another handler is called PROMISE CHAINING Promise ChainingWe might be in a situation where we need a result of an asynchronous operation in other another one With the Promise API we can pass down return result from one handler to another This method is called PROMISE CHAINING When passing down the return result the next handler pick up the result first before moving forward Syntax myPromise then then then const myPromise new Promise resolve reject gt setTimeout resolve myPromise then result gt console log result return result then result gt return result then result gt console log result return result then result gt console log result return result then result gt console log result In the example above the return result trickles down the chain and gets used by the next handler in the chain Error Handling in a Promise ChainWhen using Promise Chaining a good practice is to handle errors that might occur during promise execution The most prominent method used for handling chained promise errors is to attach a catch handler to the end the Promise chain const myPromise new Promise resolve reject gt setTimeout gt resolve myPpromise then result gt console log result return result then result gt console log result return result then result gt console log result return result then result gt console log result catch error gt console log error This handles any error in the chain In the example above if an error is encountered in the promise chain the catch block will get implemented thereby raising an error with a reason For instance if an error is encountered in the second then block the error will be caught by the catch and the rest of the then will not be executed We might want to handle an error in a specific block and still maintain the results of a Promise chain The effective approach is to wrap the specific instruction in a try catch block By doing so we handle the error locally without breaking the flow of the Promise chain const myPromise new Promise resolve reject gt setTimeout gt resolve myPromise then result gt console log result return result then result gt console log result try if result throw new Error Oops Something went wrong here catch error console log error Oops Something went wrong here return result then result gt console log result return result then result gt console log result catch error gt throw new Error error In the example above a try catch block is used to handle the error that might occur in the second code block and we can still maintain the flow control of the returned result down the chain Putting it togetherIn this section we will be implementing what we ve learned so far We will be fetching weather data from a weather API and we will be using Promise to handle the asynchronous operation On this task we are going to be making use of a weather API to request for the current weather details of a specific city You can check their official website Weather API and sign up to obtain your API key function getData city const api key your api key const url current json key api key amp q city fetch url then response gt if response ok throw new Error Error response status return response json then data gt console log data catch error gt console log error getData New York Output In the code sample above the getData function takes a city parameter input then we construct the API URL by combining the Weather API endpoint with an API key and a specified city The fetch function is used to send an HTTP GET request to the constructed URL the fetch function returns a Promise which is chained with then to handle the response In the first then method we check if the response is successful using the response ok property If the response is not successful it throws an error with a status code The response proceeds with the result to the next then if the response is successful In the second then block it parses the response using response json to obtain the weather data then it logs the retrieved weather data to the console If any errors occur during the fetch method request or data processing they are caught and logged in the catch callback To use the getData function and fetch the data for a specific city you call the getData and passing in the name of a city Promises best practices and tipsHandle both resolved and rejected states Always handle both the resolved onfulfilled and rejected onRejected states of a Promise Use the then method to handle the resolved and catch method to handle the rejected state Cleanup using finally You might want to perform some cleanup operation such as closing connections or releasing some resources regardless of whether the Promise is fulfilled or rejected You can use finally method regardless of what the the outcome might be finally method should not a return a statement Avoid using Promise constructor unnecessarily In most cases it is recommended to use Promise based API s e g fetch setTimeout Instead of manually constructing a Promise using new Promise constructor This helps to simplify code and reduces the risk of introducing complexity and mistakes Handle error with catch To handle error in asynchronous operation use the catch to handle any rejected Promises This allows you to centralize error handling logic in a single location and avoid repetitive error handling code Remember to return Promises When creating a custom function that performs an asynchronous operation that returns a Promise make sure to return the Promise so that the callers of the function can chain then and catch as needed ConclusionBy understanding Promises and their various methods developers can write more efficient and maintainable code when working with asynchronous tasks	2023-07-04 00:44:51
