Craydent 1.0.2

by Clark Inada

Craydent is all inclusive utility library. There are several ways to use the library in NodeJS. More detailed documentation on constants can be found at Craydent Properties. More detailed documentation on methods can be found at Craydent Methods

// require with prototypes - this require will add prototypes to extend classes and add two constants ($c, $g) to the global space.
// $g is an alias to global and $c is the constant containing all the utility methods and properties.
require('craydent-array');
$c.logit($c.VERSION);
arr.prototypedMethod(args);

// require no conflict - this require is the fully modular version with no global constants, prototypes, or methods.
var $c = require('craydent-array/noConflict');
$c.logit($c.VERSION);
$c.prototypedMethod(arr, args);

// require global - this require constants and methods in the global space and add prototypes to extend classes.
// $g is an alias to global and $c is the constant containing all the utility methods and properties.
require('craydent-array/global');
logit($c.VERSION);
arr.prototypedMethod(args);
