using return () in components

I notice when creating react components sometimes the tutorials are using

const comp = props => { return ( jsx in here ) }

and sometimes just leaving them in the pointer function

const comp = props => jsx in here

Is there any situation to use either or are both ok?

From my understanding, you want to use an explicit return if there are multiple lines or your code is in a block (i.e. {}). If it's a one liner, an implicit return may look cleaner, but it's personal choice on which you prefer to use in the long run.

Both are alright, but for longer JSX snippets I prefer parentheses.
