Imagine we have a reducer to control a list of items:
function listOfItems(state: Array<Object> = [], action: Object = {}): Array<Object> {
switch(action.type) {
case 'SHOW_ALL_ITEMS':
return action.data.items
default:
// Linear Congruential Generator | |
// Variant of a Lehman Generator | |
var lcg = (function() { | |
// Set to values from http://en.wikipedia.org/wiki/Numerical_Recipes | |
// m is basically chosen to be large (as it is the max period) | |
// and for its relationships to a and c | |
var m = 4294967296, | |
// a - 1 should be divisible by m's prime factors | |
a = 1664525, | |
// c and m should be co-prime |
