Fastrandom NPM

Fastrandom

Made for your faster random needs

Fastrandom works by pregenerating an array of random values and later returns values from the array.

Usage

npm

In your project, run the following command:

npm install fastrandom --save

Require as module

var random = require('fastrandom');
var value = random(); // random value like Math.random();

Use in browser

<!-- Source -->
<script type="text/javascript" src="./src/random.js"></script>
<!-- Minified -->
<script type="text/javascript" src="./dist/random.js"></script>

<script>
var value = random();
</script>

Browser using AMD or RequireJS

define(function (require) {
  var random = require("fastrandom");
  var value = random();
});

define(["fastrandom"], function (random) {
  var value = random();
});

From CLI

npm install fastrandom -g

fastrandom

Basic usage

random(); // returns a random value like Math.random();

Other functions

// Returns object of current options
random.options

// generates a new random value to array changing out an old one in current index
random.randomChanger();

// If browser supports getters and setters then there is also:
// getter version of the random
random.random // returns a random value like Math.random(); works the same like random();

// array that contains current random values
random.randomArray // [0.1414, 0.91325, ...];

// Current index in the random array
random.currentRandomIndex // 0 ... n

Options

Define window.fastrandomOptions before requiring the script. Default options:

window.fastrandomOptions = {
    valuesCount: 10000,   // How many random values should be generated at init, more values mean less looping
    randomInterval: 30    // Interval, how often a new random value is generated (in ms),
    removeOptions: true   // if true then global window.fastrandomOptions will be deleted after init
};
