Converting JSON data into a JavaScript array and storing it in a variable

Currently, I am delving into the world of JavaScript and my instructor has assigned a task that involves utilizing information from a JSON file within our JavaScript code.

The issue I'm facing is deciphering how to effectively convert the JSON data into variables or arrays in JavaScript so that I can integrate it into my existing code seamlessly.

This is an example of how my JSON data is structured:

    "id": 0,
    "albumName":"Greatest hits",
    "artistName":"ZZ-top",
    "artistWebsite":"http://www.zztop.com/",
    "productionYear": 1992,     
    "trackList":[
        {
            "trackNumber":1,
            "trackTitle":"Gimme all your lovin'",
            "trackTimeInSeconds":241
        },
        // Other tracks included in the JSON
    ]
},

My goal is to store this JSON data in the following variable structure:

    artistName : "ArtistName",
    albumName : "AlbumName",
    noOfTracks : 0,
    prodYear : 9999,
    trackList : "",

    init : function(artistName, albumName, noOfTracks, prodYear, trackList ){
        this.artistName = artistName;
        this.albumName = albumName;
        this.noOfTracks = noOfTracks;
        this.prodYear = prodYear;
        this.trackList = trackList;

        return this;
    },

Answer №1

To begin, create a string :

let xy = JSON.stringify(...);  // insert your JSON data here

Hint: Execute this in the console.

Next, form an object :

let xz = JSON.parse(xy);

Now you have a JavaScript object that can be accessed using :

    xz.artistName = artistName;
    xz.albumName = albumName;
    xz.noOfTracks = noOfTracks;
    xz.prodYear = prodYear;
    xz.trackList = trackList;

I trust this information is beneficial. :)
