JS 生产指定长度的随机数
Array.from({length: 24}, () => Math.floor(Math.random() * 400))
//[372, 173, 356, 246, 156, 293, 140, 317, 141, 166, 39, 41, 302, 255, 14, 108, 26, 236, 273, 382, 315, 329, 75, 295]
Array.from({length: 24}, () => Math.floor(Math.random() * 400))
(24) [348, 235, 81, 121, 45, 241, 262, 132, 72, 38, 317, 381, 260, 12, 27, 163, 289, 64, 377, 258, 93, 27, 201, 207]
