let students = [
    {
        name:"",
        score:98
    },
    {
        name:"",
        score:65
    },
    {
        name:"",
        score:75
    }
];
students.sort((a,b)=>{
    return b.score-a.score;
});

output: 

[
    {name: "", score: 98},
    {name: "", score: 75},
    {name: "", score: 65}
]
< H2 > Update < / H2 > 
//split("||")"||"
//
score.sort((a,b)=>{
    scoreA = +a.split("||")[1];
    scoreB = +b.split("||")[1];
    return scoreB - scoreA;
});

//
for(var i = 0;i < score.length;iPP){
    //
    console.log(score[i].split("||")[0]);
    //
    console.log(score[i].split("||")[1]);
}

this question is actually quite basic. Let's start with Baidu before asking questions.

arrays are sorted by sort. Depending on your data format, determine what's best to do 

arr.sort((a,b)=>{
    return b-a
})

study while reading 

var testList=[......]
function sortList(a, b) {
    return b.score - a.score
}
testList.sort(sortList)
