Using Promise.race
script.js
index.html
When you need to move forward as soon as the fastest asynchronous task completes, you can use Promise.race. This method takes an array of Promises and returns a new Promise that settles as soon as any of the input Promises settles, whether that means resolving or rejecting. The returned Promise adopts the state and value (or reason) of the first Promise to settle. This makes Promise.race useful when you care only about the result of the quickest operation, such as the fastest response from multiple servers or the first completed user action. Unlike Promise.all, which waits for every Promise to finish, Promise.race moves on as soon as one finishes—regardless of whether it succeeded or failed.
