I have an array of objects that looks like this:
Array(3) [ {…}, {…}, {…} ]
0: Object { plName: "player1", plNumber: 1, score: 30, … }
1: Object { plName: "player2", plNumber: 2, score: 24, … }
2: Object { plName: "player3", plNumber: 3, score: 89, … }
I'm trying to figure out the best way to get an object with the highest value of the score property. In this case:
2: Object { plName: "player3", plNumber: 3, score: 89, … }
I would really appreciate any help :)
A simple reduce should do it.
let arr = [{
plName: "player1",
plNumber: 1,
score: 30
},
{
plName: "player2",
plNumber: 2,
score: 24
},
{
plName: "player3",
plNumber: 3,
score: 89
}
];
let result = arr.reduce((o1, o2) => o1.score > o2.score ? o1 : o2);
console.log(result);If there could be multiple high score
let arr = [{
plName: "player1",
plNumber: 1,
score: 30
},
{
plName: "player2",
plNumber: 2,
score: 24
},
{
plName: "player3",
plNumber: 3,
score: 89
},
{
plName: "player4",
plNumber: 4,
score: 24
},
{
plName: "player5",
plNumber: 5,
score: 89
}
];
let maxScoreObject = arr.reduce((o1, o2) => o1.score > o2.score ? o1 : o2);
let result = arr.filter(o => o.score === maxScoreObject.score);
console.log(result);A generic function could be something like
const data = [{
plName: "player1",
plNumber: 1,
score: 30
},
{
plName: "player2",
plNumber: 2,
score: 24
},
{
plName: "player3",
plNumber: 3,
score: 89
}
];
function maxBy(array, property) {
return array.reduce((max, item) => {
if (item[property] > max[property]) return item;
return max;
})
}
console.log(maxBy(data, 'score'));score, get the first one which is the maximum score.data.sort((a,b)=>b.score-a.score)[0]
//{plName: 'player3', plNumber: 3, score: 89}
