Record-Collection_FCC_JS

Function updateRecords keeps updated your musical album collection represented by a JSON object. Each album has a unique id number as its key and several other properties like artist or tracks.

General info

The purpose of the project is just personal learning.

Description

You are get a JSON object collection representing a part of your musical album collection. Each album in the collection has a unique id number as its key and several other properties. Not all albums have complete information.

updateRecords function takes an object like collection, an id, a prop (like artist or tracks), and a value that it must update. The function must:

  • Always return the entire object.
  • If prop isn't tracks, and value isn't an empty string, it updates or set that album's prop to value.
  • If prop is tracks but the album doesn't have a tracks property, create an empty array and add value to it. Uses hasOwnProperty to check first if the album has property "tracks".
  • If prop is tracks, and value isn't an empty string, add value to the end of the album's existing tracks array.
  • If value is an empty string, delete the given prop property from the album.

To-do list:

  • Do the same on Python
  • There's another possible solution here - must check it.

Technologies

  • Javascript ES6

Setup
