Generating random numbers

Generate random numbers between $0$ and $1$ :

Math.random()  // e.g., 0.7234567891234

For random integers in a range:

// Random integer from 0 to 9
Math.floor(Math.random() * 10)

// Random integer from 1 to 10
Math.floor(Math.random() * 10) + 1

// Random integer from min to max (inclusive)
function randomInt(min, max) {
  return Math.floor(Math.random() * (max - min + 1)) + min
}
