What is the purpose of "promises" in Node.js development, and how do they differ from callbacks?(1 Point)Promises are used for debugging code, and they are interchangeable with callbacks.Promises are a way to handle asynchronous operations in a more readable and structured manner compared to callbacks.Promises are a type of callback.Promises are used for caching data

What are the advantages of using promises instead of callbacks?

How can you handle asynchronous operations in Node.js? a. Using promises b. All of the above c. Using callbacks d. Using async/await

What does the Promise object in JavaScript represent?OptionsA synchronous operationA regular JavaScript objectAn array of valuesAn asynchronous operation that may produce a value in the future

What does the Promise.race() method do in JavaScript?OptionsExecutes all promises in parallel and returns an array of their resultsWaits for all promises in the iterable to resolveReturns a promise that resolves when all promises in the iterable resolveResolves or rejects as soon as one of the promises in the iterable resolves or rejects

1.Question 1What best describes the network operations that Node.js makes?1 pointNon-blocked operations return immediately without added processing time on the serverNon-blocked operations return in a synchronized manner with added processing time on the serverApplications block every network operation to complete at the same time on the serverBlocked operations return immediately without added processing time on the server2.Question 2Before the Node.js framework receives the HTTP response message from the remote web server, it immediately returns a result for the http.request function call. What does this result state?1 pointThe callback function was called successfully.A request is in progress.The return message will be sent successfully.The response message will be sent successfully.3.Question 3What parameter is optional in an HTTP request?1 pointEvent variable parameterResource variable parameterCallback function parameterLocation function parameter4.Question 4What object do Node.js modules in the SDK pass as the first parameter in a callback function?1 pointIdentityLocationDestinationError5.Question 5What do you pass back in the callback handler to indicate a successful return?1 pointError404 status codeNull objectEmpty string6.Question 6Which function calls the resultCallback callback function to return results to the main application?1 pointstep()aggregate_context()http.request()result()7.Question 7Why can inversion of control be an issue when using callbacks?1 pointInversion of control creates the need for nested callbacksCallbacks sometimes hand over control to third-party code which can make errors hard to identifyInversion of control is used when something needs to be done sequentially which makes code readability difficultInversion of control uses promises which are difficult to implement8.Question 8JSON is the standard format for API data exchange.
