--- id: false-in-jsx title: False in JSX layout: tips permalink: false-in-jsx.html prev: initial-ajax.html next: communicate-between-components.html --- Here's how `false` renders in different contexts: Renders as `id="false"`: ```js /** @jsx React.DOM */ React.renderComponent(<div id={false} />, mountNode); ``` String `"false"` as input value: ```js /** @jsx React.DOM */ React.renderComponent(<input value={false} />, mountNode); ``` No child: ```js /** @jsx React.DOM */ React.renderComponent(<div>{false}</div>, mountNode); ``` The reason why this one doesn't render as the string `"false"` as a `div` child is to allow the more common use-case: `<div>{x > 1 && 'You have more than one item'}</div>`.
