Getting max value(s) in JSON array

Question

I\'m trying to create a JavaScript function which takes information from an array in an external JSON and then takes the max value (or the top 5 values) for one of the JSON

Answer 1

the more simple:

const players =                                           
  [ { player: 'Andre Drummond',  team: 'Detroit Pistons',      ppg: '15.4', rpg: '11.6', apg: '2.4', bpg: '1.6', spg: '0.8', '3pg': '0.1' } 
  , { player: 'Anthony Davis',   team: 'New Orleans Pelicans', ppg: '16.4', rpg: '13.6', apg: '2.6', bpg: '3.5', spg: '1.2', '3pg': '0.1' } 
  , { player: 'Carmelo Anthony', team: 'New York Knicks',      ppg: '27.4', rpg: '5.4',  apg: '4.5', bpg: '1.1', spg: '1.5', '3pg': '1.6' } 
  ] 

const getPlayerMax_on = cod => players.reduce((a,c)=>((+a[cod])<(+c[cod]))?c:a)

const maxOn_ppg = getPlayerMax_on('ppg')

console.log( maxOn_ppg.player, maxOn_ppg.team, maxOn_ppg.ppg )
