Shorthand for prop={false}

Feature Request

<Foo bar/>

is the same as

<Foo bar={true}/>

It would be nice to have something like

<Foo !bar/>

meaning

<Foo bar={false}/>

[salvoravida]

< Foo /> => this.props.bar===undefined==false.

why need !bar ?

It's unlikely that we'd do this. In either case this would be a change to JSX, which would require a change to the specification. Please see https://github.com/facebook/jsx
