"Can I run an effect only on updates?"

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 :)

Comece pelo parágrafo do FAQ intitulado “Can I run an effect only on updates?” e compare-o com a documentação de hooks. Decida se o parágrafo deve ser movido ou incluir termos de busca como componentDidMount e “avoid initial mount”; considera-se concluído quando a melhoria escolhida na documentação estiver claramente refletida.
