生成10到20之间的随机整数: let randomFrom10To20 = Math.floor(Math.random() * (20 - 10 + 1)) + 10; console.log(randomFrom10To20); 这里通过先扩展随机数的范围到所需的范围宽度(即20-10+1),然后将结果向下取整并加上范围的下限,就可以得到所需范围内的随机整数。 通过这些方法,我们能够利用Jav...

The return value from this function is random number between 0 and 1. As we have to remove the decimal part to get random numbers between 0 to 10. We will multiply the random number returned by math.random() by 11 and then take the floor value of it to get the random number. We...
