Why do people put { " " } in their React / JSX?

Question

I have this in some React documentation, as well as screencasts. People will write

{ " " }

inside of their JSX templates.

Why do they do this? It looks like they are using it as an alternative to line breaks, but I don't see that explicitly explained anywhere.

Recommended for you: Get network issues from WhatsUp Gold. Not end users.

Answer 1

This is used to put an explicit space in a text block, since leading and trailing spaces are ignored at compile/transformation time when there is another tag.

Example:

<div>
 Text
 <a>some Text</a>
</div>

Will result with Textsome Text on the screen. (see the missing space)

<div>
 Text{' '}
 <a>some Text</a>
</div>

Will result as wanted with Text some Text on the screen.
