Array.sort 在不同浏览器中的排序稳定性

这是一个老问题，我认为如果我们在这里收集最新数据会很有帮助。请点击这个小提琴

并分享您的结果。

小提琴代码：

a = []
for(var i = 0; i < 1000; i++) {
    a.push({'key':100 + Math.round(Math.random() * 100), 'val': i + 1000 })
}

a.sort(function(x, y) { return x.key - y.key })

b = []
for(var i = 0; i < 1000; i++) {
    b.push(a[i].key * 10000 + a[i].val);
}

c = b.slice(0)
b.sort()
stable = (b.join() === c.join())

document.body.innerHTML = navigator.userAgent.toString() + "<br>" + (stable ? "stable": "UNSTABLE")
