Rhythm action game example

Here is an example of how JSON.parse and JSON.stringify could be used in the context of a rhythm action game:

Let's say that the game has a feature for creating and saving custom songs, and the player can choose the notes and timing for each song. The game could store this data in a JSON file, with each song represented as a JSON object containing properties for the song's name, artist, and an array of objects representing the notes in the song.

To save a new song, the game could use JSON.stringify to convert the song data to a JSON string, and then save the string to a file:

const newSong = {
  name: 'My Awesome Song',
  artist: 'Me',
  notes: [
    {
      time: 1000,
      note: 'C'
    },
    {
      time: 2000,
      note: 'D'
    },
    // more notes...
  ]
};

const jsonString = JSON.stringify(newSong);

// save jsonString to a file using filesystem API

To load a saved song, the game could use JSON.parse to parse the JSON string from the file and create a JavaScript object from it:

// read jsonString from file using filesystem API

const savedSong = JSON.parse(jsonString);

console.log(savedSong.name); // "My Awesome Song"
console.log(savedSong.artist); // "Me"
console.log(savedSong.notes[0].time); // 1000

In this example, the newSong object represents a custom song created by the player, with properties for the song's name, artist, and an array of objects representing the notes in the song. We use JSON.stringify to convert the object to a JSON string, which is then saved to a file.

To load the saved song, we read the JSON string from the file and use JSON.parse to parse the string and create a JavaScript object from it. We can then access the object's properties to retrieve the song's data.
