React: how add key for fragment

[behnammodi]

before i use

<Fragment key={index}>
now i use

<>

how add key this ?

< key={index}> has error

@uxitten Syntax works only for propless fragments. If you need to add key, just use React.Fragment. There's nothing wrong with it.

@pd4d10 thanks i know i can use but my question is something else

[behnammodi]

@TrySound thanks but why?

[TrySound]

@uxitten To not add complexity to the syntax.

[behnammodi]

@TrySound i thought <> is just alias <Fragment>

[TrySound]

It's syntax extension which is transformed to React.Fragment, not alias

[behnammodi]

@TrySound thanks

i added this note in docs reactjs.org

https://github.com/reactjs/reactjs.org/commit/2f88a5e7eb960ff072c68d2ef536bc73fd1e051c

Isn't this clean enough?
