It is in fact a little better because.sample()only needs one random number (between 0 and.length - 1) while Fisher–Yates needsnrandom numbers. classCombination An iterable which emits a combination of a given iterable. new Combination(seed, size) ...

**注意:**ES5 版本对许多 polyfill 都具有隐式依赖,而 exceljs 不再明确添加。 您需要在依赖项中添加core-js和regenerator-runtime,并在导入exceljs之前在代码中包含以下引用: // exceljs 所需的 polyfillsrequire('core-js/modules/es.promise');require('core-js/modules/es.string.includes');require('core...
DespiteMath.random()being capable of producing numbers within [0, 1), there are a few downsides to doing so: It is inconsistent between engines as to how many bits of randomness: Internet Explorer: 53 bits Mozilla Firefox: 53 bits
It should compute a random integer between 1 and 2^bits-1. The output must be a String of length bits containing random 1's and 0's (cannot be ALL 0's). When secrets.setRNG() is called, it tries to check the PRNG to make sure it complies with some of these demands, but ...
17、randomIntegerInRange 返回指定范围内的随机整数。 使用Math.random()生成一个随机数并将其映射到所需的范围, 使用Math.floor()使其成为整数。 const randomIntegerInRange = (min, max) => Math.floor(Math.random() * (max - min + 1)) + min; // randomIntegerInRange(0, 5) -> 2 18、rand...
