Return the number of digits that are divisors of n. Let's use an example. let n = 426; Our variable n is 426 and the digits that make up the number are 4, 2, and 6. Let's divide 426 by each of those digits and see which digit is a divisor of 426. 426 / 4 = 106.5 // not a whole number, therefore not a divisor. 426 / 2 = 213.The first line (line 2 above) declares a variable called userGuess and sets its value to the current value entered inside the text field. We also run this value through the built-in Number() method, just to make sure the value is definitely a number. Next, we encounter our first conditional code block (lines 3–5 above).
