Faker.random.arrayElement(['January', 'February', 'March']); 1. 2. 正如评论者提到的那样,通常不应在生产代码中使用此库。 #16楼 简单功能: var myArray = ['January', 'February', 'March']; function random(array) { return array[Math.floor(Math.random() * array.length)] } random(myArr...
random( array: any[] ) Get random array element. import{random}from'rangen';constrandomFruit=random(['banana','apple','orange']);// apple user( params?: UserParams ) Generate random user data import{user}from'rangen';consttestUser=user(); ...
console.log(arraypro.getData(1)); //输出:2 console.log(arraypro.size); //输出:6 console.log(arraypro.last); //输出:6 当然ES5也可以扩展内置类型,但方法相对复杂且并不支持真正array的性质,ES6可以非常自然的完成内置类型的扩展功能。 五、元编程 △ 5.1、Reflect 反射 Reflect是ES6中新增加的一个对...
用Math.floor(Math.random()*10);时,可均衡获取0到9的随机整数。 Math.ceil(n); 返回大于等于n的最小整数。9.7>10 用Math.ceil(Math.random()*10);时,主要获取1到10的随机整数,取0的几率极小。 JS操作数组: 1、数组的创建: vararrayObj =newArray(); ...

provided, only the first element will be used to sign the session ID cookie, while all the elements will be considered when verifying the signature in requests. The secret itself should be not easily parsed by a human and would best be a random set of characters. A best practice may ...

And the object has.at(n)method so you can random-access each element. This is the equivalent of subscript inArray. It was previously named.nth()but it was renamed to.at()alaArray.prototype.at()in ES2020..nth()still available for backward compatibility. ...
