Stop for a second. Do you see this a lot in your code?:

	if (typeof var1 === 'string' && var1.length > 0) {
		// other code here...
	}

I see it all the time -- and in tons of places too. Or, my favorite:

	if (typeof var2 === 'object' && var2 !== null) {
		// but what if it's an empty object?
	}

Well, lets collectively stop that. Lets use simple functions to do that for us! es6-javascript-validators is a collection of functions which will do all of this for you and keep your code consistent and clean.

Available Methods

• isNullOrUndefined: Is it null or undefined?
• isStr: Is it a string?
• isArr: Is it an array?
• isNum: Is it a number?
• isObj: Is it an object?
• isFnc: Is it a function?
• validStr: Is it a string and not an empty one?
• validArr: Is it an array and not an empty one?
• validNum: Is it a number and greater than 0?
• validObj: Is it an object and not an empty one?
• ...Or, if you want all of them, just export the default object which contains all of the above.

Import specific functions

	import { isStr, isObj } from 'your/path/to/module.js';

	console.log(isStr('')); // true
	console.log(isStr([])); // false
	console.log(isStr(null)); // false
	console.log(isStr(0)); // false

	console.log(isObj('')); // false
	console.log(isObj([])); // false
	console.log(isObj(null)); // false
	console.log(isObj({})); // true

Import all utils

	import Util from 'your/path/to/module.js';

	console.log(Util.isObj({})); // true
	console.log(Util.validObj({})); // false
	console.log(Util.validObj({ a:1, b:2 })); // true

	console.log(Util.isStr('')); // true
	console.log(Util.validStr('')); // false

	console.log(Util.isArr([])); // true
	console.log(Util.validArr([1, 2, 3])); // true

	//.. and so on
