How to use switch statement inside a React component?

In contrast to other answers, I would prefer to inline the "switch" in the render function. It makes it more clear what components can be rendered at that position. You can implement a switch-like expression by using a plain old javascript object:

render () {
  return (
    <div>
      <div>
        {/* removed for brevity */}
      </div>
      {
        {
          'foo': <Foo />,
          'bar': <Bar />
        }[param]
      }
      <div>
        {/* removed for brevity */}
      </div>
    </div>
  )
}

Try this, which is way cleaner too: Get that switch out of the render in a function and just call it passing the params you want. For example:

renderSwitch(param) {
  switch(param) {
    case 'foo':
      return 'bar';
    default:
      return 'foo';
  }
}

render() {
  return (
    <div>
      <div>
          // removed for brevity
      </div>
      {this.renderSwitch(param)}
      <div>
          // removed for brevity
      </div>
    </div>
  );
}
