random () Returns random number greater than or equal to 0, and less than 1 round (x) Rounds number to closest integer sin (x) Returns the sine of x sqrt (x) Returns the square root of x 4.1. Keeping an Incremental Counter Problem You want to maintain an incremental counter in code...
constgreeting2=createNewElement('p','Hello!')console.log(greeting2)// p>Hello! 函数调用作为默认参数 除了原始类型和对象外,调用函数的结果可以用作默认参数。 在下面代码中,创建一个返回随机数的函数,然后将结果用作多维数据集函数中的默认参数值: 代码语言:javascript 复制 functiongetRandomNumber(){returnM...
Props to @mwag for giving me the start to create this. As @RobW notes, restricting the password to a fixed number of characters as proposed in the OP scheme is abad idea. But worse, answers that propose code based onMath.randomare, well, areally bad idea. ...
