node 版本 v0.10.28
var a = {"1": 40, "2": 20, "3": -10};
var b = {"1": 20, "2": 10, "3": 1};
for (var i = 0; i < 10000; i++) {
var id = 1;
var score1 = a[3] - b[3];
var score2 = a[1] - b[1];
console.log("score1=" + score1 + " score2=" + score2);
var min = Math.min(score1, score2);
console.log(min);
}
Math.min 比较这个 前面几次循环都是正确的 -11 但是后面若干次输出都是 20
如下：
score1=-11 score2=20
-11
score1=-11 score2=20
-11
score1=-11 score2=20
-11
score1=-11 score2=20
20
score1=-11 score2=20
20
score1=-11 score2=20
20
