People, I just ran this simple script on my terminal using Node and I got a pretty uniform result.

  a = {}
  for(let i = 0; i < 100000; i++){
    let n = Math.floor(Math.random() * 10);
    if( n in a )
      a[n] += 1
    else
      a[n] = 1
  }

My result:

{ '0': 9917, '1': 10015, '2': 9957, '3': 10107, '4': 10019, '5': 10037, '6': 10120, '7': 9914, '8': 10042, '9': 9872 }

> real-life sets of numerical data

Today you learned: Node’s random number generator isn’t selecting from a real-life set of numerical data

yeah, I just mixed two informations. I thought the other person said my algorithm would be biased towards small numbers cause I use the JS random function to pick the number of decimal places for the number

Yep, sorry, didn't mean to say this directly applied, just a neat concept that's somewhat related.

Sure but that’s not the algorithm you used in the repo.
