The following example generates a random integer between 0 and 99 (inclusive) by multiplying the random decimal by 100 and rounding down using Math.floor() − constresult=Math.floor(Math.random()*100);document.write(result); Output As we can see in the output, it generates...
函数式编程是一种强调和使智能化代码编写的风格,可以最大程度地减少复杂性并增加模块化。这是一种通过巧妙地改变、组合和使用函数来编写更清洁的代码的方式。JavaScript 为这种方法提供了一个极好的媒介。互联网的脚本语言 JavaScript 实际上是一种本质上的函数式语言。通过学习如何暴露它作为函数式语言的真实身份,我们...

这是我们都在使用的一种常用的简便技巧,在这里仍然值得再提一下。 注意:如果 test1 有值,将执行 if 之后的逻辑,这个操作符主要用于 null 或 undefinded 检查。 4. 用于多个条件判断的 && 操作符 如果只在变量为 true 时才调用函数,可以使用 && 操作符。

If we also want to have a user-defined minimum value, we need to change the equation ofMath.random() * maxtoMath.random() * (max-min)) +min. Using this equation the returned value is a random number betweenminandmax. functiongenerateRandomInt(min,max){returnMath.floor((Math.random()...
