In JavaScript, we can generate random numbers using the Math.random() function. Unfortunately, this function only generates floating-point numbers between 0 and 1.In my experience, it's much more common to need a random integer within a certain range. For example, a random number between 10...

{// Each iterator instance must iterate the range independently of// others. So we need a state variable to track our location in the// iteration. We start at the first integer >= from.letnext =Math.ceil(this.from);// This is the next value we returnletlast =this.to;// We won'...
