How do you program a randomizer?

27. There! Generating a sequence of random numbers is quite difficult because we want certain assumptions about this sequence to be true! Note that “Random” number generators produce what are called “pseudo” random numbers, meaning that the numbers only “approximate” real randomness.

Example Algorithm for Pseudo-Random Number Generator

1. Accept some initial input number, that is a seed or key.

4. Repeat the process to emulate randomness.

How do I generate a random number in JavaScript?

To generate a random number in JavaScript, simply use the following code: var randomnumber=Math.floor(Math.random()*11) where 11 dictates that the random number will fall between 0-10. To increase the range to, say, 100, simply change 11 to 101 instead.
