JS - 数组元素比较大小问题

Question

如图所示，定义a、b两个数组，然后进行循环比较，c数组存放两个数组比较后的那个较小的值，结果c数组的第一个值是那个较大的值，剩下的才是较小的值，请问这是什么原因？备注：（代码如下）var a = ["429", "14302", "1", "0", "0", "159", "20", "0"];var b = ["1542", "46886", "4", "0", "0", "644", "2", "0"];var c = [];for(var i = 0, length = a.length; i < length; i++) {if(a[i] < b[i]) {     c.push(a[i]); } else {     c.push(b[i]); }}console.log(c);

Answer 1

先将字符串转成数字再比较 否则是按 ASCII 码比较大小

console.log('429' < '14302'); // false

console.log(Number('429') < Number('14302')) // true
