short-methods

Useful shorthand methods mostly for arrays but see the list below.

About

All methods defined tries to work w/ the given array, avoiding creating a new one. Except if thats the direct intent of the function (.clone).

By requiring it, the returned object will be a function. It has the full API on its properties, however you also extend a simple object or the original prototypes (this is DANGEROUS, only use it if you know what you're doing).

Install

# Navigate to your projects directory and use npm to install it as a dependency: npm install -S short-methods

Usage

In your code: var shortMethods = require('short-methods');

After this you can use it multiple ways:

var
  array;

# Use the properties of the returned object:

array = [1, 2, 3];

shortMethods.array.remove(array, 2);    // ===> array [1, 3];
shortMethods.array.removeAt(array, 2);  // ===> array [1, 2];

# Use the properties of the returned object in short format:

array = [1, 2, 3];

shortMethods.a.remove(array, 2);    // ===> array [1, 3];
shortMethods.a.removeAt(array, 2);  // ===> array [1, 2];

# Extend a specific object:

array = shortMethods([1, 2, 3]);

array.remove(2);   // ===> array [1, 3];
array.removeAt(2); // ===> array [1, 2];

# Extend prototypes (this is DANGEROUS, only use it if you know what you're doing):
shortMethods(true);

array = [1, 2, 3];

array.remove(2);    // ===> array [1, 3];
array.removeAt(2);  // ===> array [1, 2];

Short list w/ the default behavior, for more info about parameter usage check out the specs.
