mass-random

A quick and easy library that allows you to get random letters, ints, floats, strings, and also a random item from statistics

##Random Integer

  random.int(0,1)

##Random Float

  random.int(0,1)

##Random Letter

  var letters = random.int(3);
  //letters will be equal to a string with 3 random letters from the alphabet

##Random String

  var string = random.string(10);
  //string will a string 10 characters long with each character being a random number / letter

##Random Item from stats

  var stats = new random.statistics({
    bannana: 1,
    apple: 1
  });
  //or
  var stats = new random.statistics(['bannana', 'apple']);

  //There will be an equal chance that the item will be a banana or an apple
  var randomItem = stats.randomItem();

  //Increase the weighting of the bannana by one, so it is now double the weighting of an apple. (because default weighting of a item is 1)
  stats.stats.bannana += 1;

  //Now there will be double the chance that there will be a bannana than a apple
  var randomItem = stats.randomItem();

##Random Item from stats with dynamic weighting

var random = require('mass-random');

var statistics = new random.statistics({
  "Probably Day": {
    0: 0.5,
    1: 0.5,
    2: 1,
    3: 1.5,
    4: 1.5,
    6: 2,
    7: 2.5,
    8: 3,
    9: 3.5,
    10: 4,
    11: 5.5,
    12: 6,
    13: 5.5,
    14: 5,
    15: 4.5,
    17: 4,
    18: 3.5,
    19: 3,
    20: 2.5,
    21: 2,
    22: 1.5,
    23: 1
  },
  "Probably Night": {
    0: 6,
    1: 6,
    2: 5.5,
    3: 5,
    4: 4.5,
    6: 4.5,

    8: 3.5,
    9: 3,
    10: 2.5,
    11: 2,
    12: 1.5,
    13: 1,
    14: 1.5,
    15: 2,
    17: 2.5,
    18: 3,
    19: 3.5,
    20: 4,
    21: 4.5,
    22: 5,
    23: 5.5
  }
});

statistics.weightingCalculator = function(item){

  var time = Date().split(' ')[4].split(':')[0]; //Current Hour

  var simple = false;
  //Simple is just to show  a basic way of useing this function.
  //Or you could read into the else statement for a more practical
  //use if say it was songs to play on a radio as the object keys in stead of a statement

  if (simple){
    return item[time];
  }else{
    var prevHour = time-1;
    //Loop time around
    if (prevHour < 0){
      prevHour = 23;
    }

    var nextHour = time+1;
    //Loop time around
    if (nextHour > 23){
      nextHour = 0;
    }

    return ((item[prevHour]/2) + (item[nextHour]/2) + item[time])/2;
    //The two hours on each side of the current time make up two halfs of a weighting
    //Then we add the current times weighting
    //Then devide that by 2 so it is equal to one weighting
  }
};

console.log(statistics.randomItem());
