使用ramda获取列表中最大的项目

Question

我正在尝试 return 列表中最大的元素 page:

page = [1,2,3];
R.max(page); // returns a function.
R.max(-Infinity, page); // seems correct but doesn't work as expected.

Answer 1

我没有安装 ramda 包，所以这是未经测试的，但是从文档 max() only takes two arguments, so you would have to reduce() 你的阵列上看：

var page = [1, 2, 3],
    result = R.reduce(R.max, -Infinity, page);
// 'result' should be 3.

Answer 2

const page = [1, 2, 3];
R.apply(Math.max, page); //=> 3
