I'm not sure what the HTML file is supposed to do, but the js file takes from the "Math" library the random() function which generates a random float from 0 to 0.999999, times is by the "age" parameter and then uses the floor() function, which rounds the number down. In summery, it creates a number from 0 to the age that you put into it. Although you did forget to return that result. And when you called the function random_age() you didn't put a value into it.
