배열에서 가장 높은 점수의 Javascript 리턴 발생

최소 및 최대 값 찾기 :

var array = [{name:'abc',score:2},{name:'gdf',score:2},{name:'ghd',score:3},{name:'asdf',score:4},{name:'qwer',score:4}];
var max = -Infinity; 
var min = +Infinity; 
array.forEach(function(obj) {
    if(obj.score > max) {
        max = obj.score;
    }
    if(obj.score < min) {
        min = obj.score;
    }
});

그리고 그 정보를 사용하여 배열을 필터링하십시오 :

var highestoccurence = array.filter(function(el) {
    return el.score == max;
});
var lowestoccurence = array.filter(function(el) {
    return el.score == min;
});

다음과 같은 방법으로 할 수 있습니다

let array = [{name:'name',score:2},{name:'name2',score:2},{name:'name3',score:3},{name:'name4',score:4},{name:'name5',score:4}];

let max = array.reduce(function(a, b){
    if(a.score > b.score)
        return a;
    return b;
})
max_array = array.filter(function(element){
    return element.score == max.score;
});
console.log(max_array);

let array = [{name:'name',score:2},{name:'name2',score:2},{name:'name3',score:3},{name:'name4',score:4},{name:'name5',score:4}];

let min = array.reduce(function(a, b){
    if(a.score < b.score)
        return a;
    return b;
})
min_array = array.filter(function(element){
    return element.score == min.score;
});
console.log(min_array);

Lodash를보십시오.

const maxItems = _.filter(array, { score: _.maxBy(array, 'score').score });
const minItems = _.filter(array, { score: _.minBy(array, 'score').score });

_.maxBy(array, 'score')  첫 번째 최대 점수 항목을 반환합니다.

_.filter(array, { score: maxItem.score })  최대 점수와 동일한 점수를 가진 항목을 반환합니다.

higher 에 대해 별도로 확인  그리고 lower  배열을 만듭니다

array = [{name:"name",score:2},{name:"name2",score:2},{name:"name3",score:3},{name:"name4",score:4},{name:"name5",score:4}];
highest = [];
highestScore = 0;
lowest = [];
lowestScore = 0;
for(i in array){
  if(i == 0){
    lowestScore = array[i].score;
    highestScore = array[i].score;
    lowest.push(array[i]);
    highest.push(array[i]);
  }else{
    if(array[i].score <= lowestScore){
      if(array[i].score != lowestScore){
        lowest = [];
        lowestScore = array[i].score;  
      }
      lowest.push(array[i]);
    }
    if(array[i].score >= highestScore){
      if(array[i].score != highestScore){
        highest = [];
        highestScore = array[i].score;  
      }
      highest.push(array[i]);
    }
  }
}
console.log("lowest",lowest);
console.log("highest",highest);
