Question 76/110

Universal Containers (UC) notices that its application that allows users to search for accounts makes a network request each time a key is pressed. This results in too many requests for the server to handle.
Address this problem, UC decides to implement a debounce function on string change handler.
What are three key steps to implement this debounce function?
Choose 3 answers:

A. When thesearch string changes, enqueue the request within a setTimeout.

B. If there is an existing setTimeout and the search string changes, cancel the existingsetTimeout using thepersisted timerId and replace it with a new setTimeout.

C. Store the timeId of the setTimeout last enqueued by the search string change handle.

D. Ensure that the network request has the property debounce set to true.

E. If there is an existing setTimeout and the search string change, allow the existingsetTimeout to finish, and do not enqueue a new setTimeout.

Correct Answer: A,D,E

Should be A, B and C.
We do not let the previous setTimeout finish their job if the user presses another key, that's the pricniple of debouncing, and to achieve it we need to keep stored the previous timerId to cancel it and generate a new setTimeOut.
