arrays - Node.js，找到最大的对

Question

对于 Node.js，我怎样才能找到 ["5",0.668574]，它是下面最大的：

[[["0",0.0137134],["1",0.0156018],["2",0.142732],["3",0.14874],["4",0.0151308],["5",0.668574]] ]

谢谢 ！

Finally figured out with the help of Piyush N. Thanks Community !

var pairs = [[["0",0.0137134],["1",0.0156018],["2",0.142732],["3",0.14874],["4",0.0151308],["5",0.668574]]];

var max = ((pairs [0])[0])[1];
var maxPair = (pairs [0])[0];  
pairs[0].forEach(pair => {
    if(pair[1] > max) {
    max = pair[1];
    maxPair = pair;
  }
});

console.log(maxPair);

谢谢，皮尤什！这很有帮助！

我可能误导了你，一对中的第一项是字符串，我希望得到第二项最大的那对。按照你的逻辑，我想通了，它的工作原理！

请注意，与您的 var 对相比，原始 var 对多了一组 []。

var pairs = [[["0",0.0137134],["1",0.0156018],["2",0.142732],["3",0.14874],["4",0.0151308],["5",0.668574]]];

var max = ((pairs [0])[0])[1];
var maxPair = (pairs [0])[0];  
pairs[0].forEach(pair => {
    if(pair[1] > max) {
    max = pair[1];
    max = max;  
    maxPair = pair;
    maxPair = maxPair;
  }
});

console.log(maxPair);
