Cannot locate the state variable

import React, { Component } from 'react';
import { View, Text } from 'react-native';
import axios from 'axios';

class AlbumList extends Component {
    state = { albums: [] } ;

    componentWillMount(){
        axios.get('https://rallycoding.herokuapp.com/api/music_albums')
        .then(response => this.setState({ albums : response.data }));
    }


    renderAlbums(){
        return this.state.albums.map(album => <Text>{album.title}</Text>)
    }

    render(){
        console.log(this.state);
        return (
            <View>
               {this.renderAlbums()}
            </View>
    );
    }
}

export default AlbumList;

I encountered a "referenceError: Can't find variable: albums" issue that appeared suddenly after working fine. Any idea what might be causing this?

Answer №1

It appears there is a discrepancy with your mapping variable. Consider the following:

return this.state.albums.map(album => <Text>{album.title}</Text>)

You have used album as the variable name for the function, yet you are referencing albums.title.
