javascript - I want to pull the names with the top 5 values out of an object...in React -

i have state set empty object. when searched returns list of names values inside of object. how pull names top 5 values names render?

here initial state:

export default class app extends react.component {   constructor() {     super();     this.state = {       searchinput: '',       selectedartist: {},       selectalbums: {},       artistcounts: {},     }; 

here fucntion gets names , gives them value:

gettrackdetails(track) {     request.get(`api`)       .then((track) => {         const { artists } = track.body;         const artistcounts = this.state.artistcounts;         (let = 0; < artists.length; i++) {           const artist = artists[i];           const artistname = artist.name;           if (artistcounts[artistname]) {             artistcounts[artistname] += 1;           }           else {             artistcounts[artistname] = 1;           }         } 

not sure getting right looks need limit

for (let = 0; < artists.length; i++) { 

to run 5 times so:

var maxlength = artists.length >= 5 ? 5 : artists.length;  (let = 0; < maxlength ; i++) {
