来自不同数组的相同元素的和

Question

我有很多数组。我可以将它们与for循环一起列出，但是，如果这些不同的数组中有相同的元素，我只需要显示每个元素一次。例如；

var array01 = [["Jack","92"],["Tom","74"],["Lily","100"],["Jonah","62"],["Lucy","83"]];
var array02 = [["Tom","94"],["Emma","70"],["Jack","100"],["Arnold","91"],["Kate","53"]];
var array03 = [["Jack","72"],["Tom","84"],["Emma","91"],["Jonah","92"],["Lucy","63"]];
var array04 = [["Emma","88"],["Marshall","82"],["Arnold","68"],["Ted","62"],["Lily","73"]];
var array05 = [["Jonah","87"],["Lucy","86"],["Kate","71"],["Jack","66"],["Lily","93"]];

我想将结果从最高值到最低值排序如下：

杰克: 330

莉莉: 266

汤姆: 252

艾玛: 249

约拿: 241

露西: 232

阿诺德: 159

凯特: 124

马歇尔: 82

泰德: 62

Answer 1

您可以使用reduce将所有数组合并为一个值，然后应用sort()进行基于score的排序。

​

var array01 = [["Jack","92"],["Tom","74"],["Lily","100"],["Jonah","62"],["Lucy","83"]];
var array02 = [["Tom","94"],["Emma","70"],["Jack","100"],["Arnold","91"],["Kate","53"]];
var array03 = [["Jack","72"],["Tom","84"],["Emma","91"],["Jonah","92"],["Lucy","63"]];
var array04 = [["Emma","88"],["Marshall","82"],["Arnold","68"],["Ted","62"],["Lily","73"]];
var array05 = [["Jonah","87"],["Lucy","86"],["Kate","71"],["Jack","66"],["Lily","93"]];

var all=[...array01,...array02,...array03,...array04,...array05];

var result = Object.values(all.reduce((acc, [key, val])=>{
    acc[key] = acc[key] || {[key]:0};
    acc[key][key]+=+val;
    return acc;
},{})).sort((a,b)=>Object.values(b)[0]-Object.values(a)[0]);

console.log(result);
