Durstenfeld 所描述的算法与 Fisher 和 Yates 所给出的算法有很小的差异,但意义重大。 -- To shuffle an array a of n elements (indices 0..n-1): for i from n−1 downto 1 do // 数组从 n-1 到 0 循环执行 n 次 j ← random integer such that 0 ≤ j ≤ i // 生成一个 0 到 n-...

用arr.forEach 替代原本的 for 循环。(我会告诉你 【array.forEach 的返回值是 undefined】这一点容易出错嘛) 不希望有人质疑:JS 由于函数调用栈空间有限,用 for 循环不是比 forEach 效率更高吗? 拿出这段话压压惊: ”We should forget about small efficiencies, say about 97% of the time: premature o...
