Looping Json & Display in React Native

Question

How do I loop the result I got from Json?

render: function() {
     console.log(this.state.list);
     contents = (
      <View style={ styles.content }>
        <Text>Loaded</Text>

      </View>
     )
     return (
      <View style={ styles.container }>
        <View style={ styles.header }>
        <Text style={ styles.headerText }>XXX</Text>
        </View>
        <View style={ styles.content }>
            { contents }
        </View>
      </View>
    );
  }

React can render an array of Elements, so you just need to create an array and assign it to a variable contents. I made an example using map.

render: function() {
     console.log(this.state.list);
     contents = this.state.list.results.map(function (item) {
        return (
          <View key={item.user.email} style={ styles.content }>
            <Text>{item.user.email}</Text>
          </View>
        );
     });
     return (
      <View style={ styles.container }>
        <View style={ styles.header }>
        <Text style={ styles.headerText }>XXX</Text>
        </View>
        <View style={ styles.content }>
            { contents }
        </View>
      </View>
    );
  }

And also: when you have an array of elements in React, you must provide a unique attribute keyfor each element in the array. Understand why . In this case, I use item.user.emailas a unique identifier, but you can use a different attribute, just make sure it is unique ( item.user.md5promises)
