Description

Hi React Team :)

After reading a first time the hooks documentation, I didn't find how to skip the first useEffect call at the initial mount. Fortunately Dan directed me to the paragraph "Can I run an effect only on updates?" from FAQ. :)

Maybe I was the first to feel a little bit confused with that. So I propose to either :

  • This paragraph shouldn't be in the FAQ, because the documentation it's dense (that's a good thing, thanks for the job) and you'll probably not going to the FAQ after reading a first time.
    (or)
  • This paragraph can stay in the FAQ, but we should add term like componentDidMount, "avoid intial mount" to make search easier.

If the idea sounds good for you guys. I can suggest you a alternative text :)

Thank you again for your job :)

Research direction

Start with the FAQ paragraph titled “Can I run an effect only on updates?” and compare it with the hooks documentation. Decide whether the paragraph should move or gain search terms such as componentDidMount and “avoid initial mount”; done means the chosen documentation improvement is clearly reflected.
