JS allows a developer to generate a random number by using two methods:
Math.random() generates a random 16 decimal place number that is greater or equal to 0 and less than 1. We can multiply the return to get a range: Math.random() * 10 // between 0 and 9.9999etc Math.floor() rounds a number DOWN to the nearest whole number. Therefore… Math.floor(Math.random( ) * 10) = a random number
between 0 and
Make a random whole number in any range with Math.random() and Math.floor(), pick a random item, shuffle a list fairly, avoid the Math.round trap, and know when to use crypto instead.

Run your code at the right moment: load versus DOMContentLoaded, window.onload versus addEventListener, defer and async scripts, document.readyState, and the mistakes that cause "null" errors.
