nou = Null Or Undefined

Tired of writing util.isNullOrUndefined? This module is for you! It creates shortcut methods such as isNou or isNull.

Usage:

const nou = require('nou');

var x; //x is undefined

nou.isNou(null); //true
nou.isNou(x); //true
nou.isNull(null); //true
nou.isNull(x); //true

nou.isNotNou(""); //true
nou.isNotNull(""); //true
nou.isDefined(""); //true

installation:

npm i --save nou

this is the actual code

const isNou = (x) => x === null || x === undefined;

module.exports = {
    isNou,
    isNotNou: (x) => !isNou(x),
    isNull: isNou,
    isNotNull: (x) => !isNou(x),
    isDefined: (x) => !isNou(x),
};
