Learn Basic Debugging by Building a Random Background Color Changer - Step 3

@Alex0 function getRandomIndex() { console.log(darkColorsArr.length * Math.random()) } This function will print out something like: 2.114596286197641 because the expression darkColorsArr.length * Math.random() is return a float number: 2.114596286197641. Now, if we want this function to print out a rounded down integer number: 2, we have to round down the expression darkColorsArr.length * Math.random() by using Math.floor(). To do that, we put the whole expression darkColorsArr.lengt…

Wishing you good progress on your coding journey.
