How to generate a random number between two numbers in JavaScript

The simplest possible way to randomly pick a number between two

Use a combination of Math.floor() and Math.random().

This simple one line of code will return you a number between 1 and 6 (both included):

Math.floor(Math.random() * 6 + 1)

There are 6 possible outcomes here: 1, 2, 3, 4, 5, 6.
