Working with this code:

function padString(data, maxLength, padCharacter, padLeft)

{

while(data.length

{

if(padLeft)

{

data=padCharacter+data;

}

else

{

data=data+padCharacter;

}

}

return data;

}

const songs = [

{

title: "Drivers License",

artist: "Olivia Rodrigo",

position: 1,

weeksOnChart: 3,

},

{

title: "Mood",

artist: "24kGoldn Featuring iann dior",

position: 2,

weeksOnChart: 25,

},

{

title: "Blinding Lights",

artist: "The Weekend",

position: 3,

weeksOnChart: 60,

},

{

----------------------------

Question:

Add padString() to catalogObject, and update addSong() and listSongs() to support padded output The output in the Console isn't very easy to read, so format the output so that each column is padded.

• Move the padString() function into the catalogObject
• Add the following properties to catalogObject to keep track of the maximum length of each column as a song is added to the catalog.
  • _maxTitleLength: Maximum title property length, initialized to the length of column header "Title"
  • _maxArtistLength: Maximum artist property length, initialized to the length of column header "Artist"
  • _maxPositionLength: Maximum position property length, initialized to the length of column header "Position"
  • _maxWeeksOnChartLength: Maximum artist property length, initialized to the length of column header "Weeks On Chart"
• Update addSong() to update each of the maximum length properties as a song is added
• Update listSongs() to use padString() and each of the maximum length properties to format the catalog Console output, and to include column headers, also padded
