It depends on who is asking for help. But for many, it doesn't help them to answer too quickly:

- sometimes it's like giving the spout to a child who doesn't know how to use a spoon yet.

- sometimes it's like answering someone who could have found the answer by searching 20 seconds on Google.

Answering too quickly can make your interlocutors dependent on you.

Similarly, before asking someone for help, it is usually a good idea to spend 30 minutes looking for the solution yourself. The time lost is more than made up for later.
