00:04 The main topic of this video is Promise APIs. 02:21 promise.all takes an array of promises as input and makes parallel API calls. 07:13 If any promise in the Promise.all array gets rejected, the Promise.all will throw an error, and the same error will be the output 09:48 The Promise APIs all and allSettled handle the success and failure of multiple promises. 15:00 Promise APIs - all, allSettled, race, any 17:31 In a race between multiple promises, the first promise to settle (either resolve or reject) will determine the result. 22:07 Promise.any waits for the first successful promise 24:38 If all promises fail, an aggregated error will be returned. 28:58 Promise APIs + Interview Questions: Explaining the functionalities of allSettled, all, race, and any 31:03 Promise.all, Promise.allSettled, Promise.race, Promise.any 35:14 Demonstration of using Promise APIs in JavaScript 37:29 Understanding Promise.all and handling errors 41:40 The promise.allSettled() method waits for all the promises to fulfill, collects all the results, and returns them. 43:41 Promise object gives an array of objects with status and value for success or rejection. 47:52 Understanding the lingo of promises: fulfilled, rejected, settle, success, failure 49:47 Promise.any waits for the first settled promise and ignores the rest 53:54 The aggregate errors in Promise APIs are returned as an array. 55:57 The speaker is requesting viewers to share and appreciate the video. 59:38 Promise APIs + Interview Questions 🔥

[@harishkanuka]

00:00 🔑 Promises APIs are crucial for interviews and everyday application development, especially when handling asynchronous operations like parallel API calls. 02:02 🔑 Promise.all handles multiple promises simultaneously, returning an array of results when all promises are fulfilled, and throwing an error if any promise fails. 06:38 🔑 If any promise in Promise.all fails, the entire operation fails, and an error is thrown immediately without waiting for other promises. 12:02 🔑 Promise.allSettled waits for all promises to settle (whether fulfilled or rejected) before returning an array of results or errors, making it suitable for scenarios where partial failures are acceptable. 16:57 🔑 Promise.race returns the result of the first settled promise, whether it's success or failure, making it ideal for scenarios where the fastest response is required. 21:52 🔑 Promise.any is similar to Promise.race but waits for the first successful promise rather than the first settled one, making it suitable for scenarios where success is prioritized over speed. 22:33 🔍 Promise.any returns the result of the first successful promise and ignores subsequent failures, waiting for success. 23:55 🏁 Promise.any collects errors if all promises fail and returns an aggregated error array. 27:05 🔄 Promise.all returns an array of all results when all promises succeed, waiting for all to finish. 28:40 🛠 Promise.allSettled waits for all promises to settle (succeed or fail) before returning results, ensuring all promises are accounted for. 31:18 🏎 Promise.race returns the result of the first settled promise, whether success or failure, racing to return the fastest result. 43:54 📝 Promise status can be checked for rejection along with the reason for rejection, providing clarity in handling errors. 44:21 🚀 Promise.race returns the result of the first settled promise, whether it's a success or failure, regardless of the order in which promises are fulfilled. 45:59 💡 Explaining concepts in interviews requires not only understanding but also the ability to articulate ideas clearly, which is often a stumbling block for many candidates. 46:13 🔑 Promise.race resolves to the value/error of the first settled promise, regardless of success or failure, emphasizing the importance of understanding terminology in the Promise world. 48:17 📚 Familiarity with Promise terminology like "settled," "resolved," "rejected," "fulfilled," and "rejected" is crucial for effectively working with Promise APIs. 49:56 📝 Promise.any waits for the first settled promise, and if it's a success, returns the result, ignoring subsequent rejections until a success occurs. 52:25 📊 When all promises fail with Promise.any, it results in an "aggregate error," which consolidates all the errors encountered during execution. 54:14 🛠 Handling aggregate errors in Promise.any involves accessing the errors in an array format, allowing for comprehensive error management and analysis.

In case of success : Wait for all to finish then so output. b. In case of failure : If any one fail then still wait other to finish then return result. [val1 , err2 , val3] 3. Promise.race -> First settled ( whether it's success or failure ) return result of first settled promise. like if ok then ok or if fail then fail 4. Promise.any -> return first settled RESOLVED(success). -> If fail then still wait for other. -> In case of all promise reject then return AGGREGRATE ERROR with value. [err1,err2,err3] */ // Typo of naming convesnion /* Settled -> got our result / \ resolve or reject success or failure fulfiled or reject */

[@sambhavsharma2780]

If there are multiple API calls with the same execution time, let's suppose we have three promises: P1 -> 1000ms, P2 -> 2000ms, P3 -> 1000ms. Here we see that P1 and P3 API calls both settled in 1000 ms. So, when I execute this code with Promise.race(), we get the result as P1 success. But my question is, why wasn't the P3 call executed? We learned that in Promise API calls, all the API calls are executed in parallel.

[@lakshmigurumurthy7009]

In the case of `Promise.race()`, it resolves or rejects as soon as one of the promises resolves or rejects. In your scenario, since both P1 and P3 settle at the same time (1000ms), `Promise.race()` just sees the first one that settles, which is P1. Therefore, P3 might have been executed, but its settlement wasn't observed because P1 settled first.

This video is awesome. I am obsessed with your teaching style. I have a question though it was asked one of my friend's Lenskart frontend interview can you plz make a video on it "Suppose I have a series of 4 promises in a JavaScript application, and I want to implement a mechanism where, if the second promise in the chain encounters an error or is rejected, it is automatically restarted or retried from the first promise (basically restart the promise chain). How can I achieve this retry functionality for a specific promise in a promise chain in JavaScript?"

[@rammondal8147]

I searched your question in ChatGPT to understand the solution, posting it here so it'll be helpful for all. async function retryablePromiseChain() { let retryCount = 0; const maxRetries = 3; // Adjust the number of retries as needed while (retryCount < maxRetries) { try { // The first promise in the chain await promise1(); // The second promise that might fail await promise2(); // The rest of the promise chain await promise3(); await promise4(); // If all promises succeed, break out of the loop break; } catch (error) { // If the second promise fails, catch the error and retry console.error(`Promise 2 failed. Retrying (${retryCount + 1}/${maxRetries})`); retryCount++; } } if (retryCount === maxRetries) { console.error('Max retries reached. Promise chain failed.'); // Handle this accordingly, e.g., throw an error or log it. } } async function promise1() { // Implement your first promise logic here } async function promise2() { // Implement your second promise logic here // If it fails, throw an error // Example: throw new Error('Failed to execute promise 2'); } async function promise3() { // Implement your third promise logic here } async function promise4() { // Implement your fourth promise logic here }

[@senthamarai_kannan.]

Promise.all is useful when you need to wait for all of the input promises to resolve before proceeding. Promise.allSettled is useful when you need to know the status of all of the input promises, regardless of whether they resolve or reject. Promise.any is useful when you only need the value of the first input promise that resolves. Promise.race is useful when you want to know the outcome of the first input promise that resolves or rejects.

Promise.any similar to race

[@mehandilone9533]

Promise.all to concurrently process multiple promises, it also fail first ,in case of facing any reject it gives that only. Promise.allSettled to handle all promise states, can be success or failure Promise.race for executing the fastest promise, it gives the first promise even success or failure Promise.any for managing the first resolved promise. If there is no success then it gives the aggregate error. If you write console.log(err.errors) in the catch block it gives the array of errors.
