How to concatenate JSX components in React Native

For example, I wanna show a list of names. So I wanted to do something like this:

var returnValue;
for (eachName of _names) {
  returnValue += (
  <TouchableHighlight
    onPress={() => this._onPressButton}>
      <Text>
      {eachName}
      </Text>
  </TouchableHighlight>);
}
return returnValue;

However, that is not valid. Which brings me to my question: How do I concatenate a dynamic amount of JSX components in React Native.

Figures I figure it out soon as I ask stackoverflow. The code needs to be put into an array:

var returnValue = [];
for (var i = 0; i < _names.length; i++) {

  returnValue.push(
  <TouchableHighlight onPress={() => this._onPressButton}>
      <Text>
      {_names[i]}
      </Text>
  </TouchableHighlight>);
}
return returnValue;

There is also more information here: http://facebook.github.io/react/docs/multiple-components.html#dynamic-children

Maybe a more elegant way:

return <View>
{_names.map((eachName) => {
  return (
    <TouchableHighlight onPress={() => this._onPressButton}>
      <Text>
      {eachName}
      </Text>
    </TouchableHighlight>
  );
})}
</View>

let returnValue = _names.map(eachName =>
 <TouchableHighlight
    onPress={() => this._onPressButton}>
      <Text>
      {eachName}
      </Text>
  </TouchableHighlight>);
return returnValue;
