in javascript you can't seed Math.random, if you want something you can seed you have to implement a PRNG yourself

i needed a function that returned a "random" value in [0, 1), like Math.random does, but seedable. importantly, it wasn't for anything even slightly cryptographic or whatever. i had absolutely no requirements for the quality of the output beyond "seems vaguely random to a person"

so here's the simplest, and probably worst (but good enough) PRNG function i found online:

let seed = WHATEVER_NUMBER;
function random() {
const x = seed++/Math.PI;
return x - Math.floor(x);
}

@monorail also, reported a second time for using a function declaration

@wallhackio is function random() {} equivalent to like var random = () => {}; and that's why it's bad or

@monorail function declarations create global variables because javascript sucks

@monorail this doesn't work in node.js for whatever reason, shittyRandom1 is not added to global scope
