根据JavaScript中的条件对数组重新排序？
假设我们有一个对象数组，其中包含纸牌游戏中某些玩家的得分-
const scorecard = [{
name: "Zahir",
score: 23
}, {
name: "Kabir",
score: 13
}, {
name: "Kunal",
score: 29
}, {
name: "Arnav",
score: 42
}, {
name: "Harman",
score: 19
}, {
name: "Rohit",
score: 41
}, {
name: "Rajan",
score: 34
}];我们还有一个名为selfName的变量，其中包含特定玩家的名字-
const selfName = 'Arnav';
我们需要编写一个函数，该函数按字母顺序对记分卡数组进行排序，并确保名称与selfName相同的对象出现在顶部（索引为0）。
因此，让我们为这个问题编写代码-
示例
const scorecard = [{
name: "Zahir",
score: 23
}, {
name: "Kabir",
score: 13
}, {
name: "Kunal",
score: 29
}, {
name: "Arnav",
score: 42
}, {
name: "Harman",
score: 19
}, {
name: "Rohit",
score: 41
}, {
name: "Rajan",
score: 34
}];
const selfName = 'Arnav';
const sorter = (a, b) => {
if(a.name === selfName){
return -1;
};
if(b.name === selfName){
return 1;
};
return a.name < b.name ? -1 : 1;
};
scorecard.sort(sorter);
console.log(scorecard);输出结果
控制台中的输出将为-
[
{ name: 'Arnav', score: 42 },
{ name: 'Harman', score: 19 },
{ name: 'Kabir', score: 13 },
{ name: 'Kunal', score: 29 },
{ name: 'Rajan', score: 34 },
{ name: 'Rohit', score: 41 },
{ name: 'Zahir', score: 23 }
]
