推荐答案

Jon Resig 在 这篇文章 中说明如何通过扩展 Array 原型并调用底层 Math.min 方法来实现这一点不幸的是，它不采用数组，而是采用可变数量的参数:

Jon Resig illustrated in this article how this could be achieved by extending the Array prototype and invoking the underlying Math.min method which unfortunately doesn't take an array but a variable number of arguments:

Array.min = function( array ){
    return Math.min.apply( Math, array );
};

然后:

var minimum = Array.min(array);
