Absent
Absent checks existence or blankness of a variable.
What is the goal of this project?
This project allows you to make both undefined checking and null checking on one method call. This makes your code more clean.

$ npm install --save absent
Usage
var helper = require('absent');
// null checking of null variable
var instance = null;
if( helper.isNull(instance) ) { ... }
var undefinedInstance;
if( helper.isNull(undefinedInstance) ) { ... }
var str = "";
if( helper.isBlank(str) ) { ... }
if( helper.isSet(str) ) { ... }
var isExist = false;
if( helper.not(isExist) ) { ... }
