fixRandom(arg0,...args) #

• Fixed random value, specified probability to return a constant

  
  

• Get a random number from 0 to the passed probability number arguments.length by probability

Example:

// Prints: 3 5 9
console.log(util.random(0, 10))
console.log(util.random(0, 10))
console.log(util.random(0, 10))
// Prints 0 3 2
console.log(util.fixRandom(10, 20, 30, 40))
console.log(util.fixRandom(10, 20, 30, 40))
console.log(util.fixRandom(10, 20, 30, 40))
