    type:

    Also checks for email, url, phone number(uses libphonenumber library), NaN, Float, Int and Infinity types

    W.type("hello world"); //'String'
    W.type(123); //'Int'
    W.type(123.23); //'Float'
    W.type(NaN); //'NaN'
    W.type(Infinity); //'Number'
    W.type(-Infinity); //'Number'
    W.type({}); //'Object'
    W.type(undefined); //'Undefined'
    W.type([]); //'Array'
    W.type(true); //'Boolean'
    W.type(new Date()); //'Date'
    W.type(null); //'Null'
    W.type("test@test.com"); //'Email'
    W.type("http://www.google.com/?q=testing"); //'Url'
    W.type("+44 7700 900804"); //'Phone'

    trueType:

    Just check for type and returns true javascript type for an object

    W.type("hello world"); //'String'
    W.type(123); //'Number'
    W.type(123.23); //'Number'
    W.type(NaN); //'Number'
    W.type(Infinity); //'Number'
    W.type(-Infinity); //'Number'
    W.type({}); //'Object'
    W.type(undefined); //'Undefined'
    W.type([]); //'Array'
    W.type(true); //'Boolean'
    W.type(new Date()); //'Date'
    W.type(null); //'Null'
    W.type("test@test.com"); //'String'
    W.type("http://www.google.com/?q=testing"); //'String'
    W.type("+44 7700 900804"); //'String'

    isNaN:

    W.isNaN(NaN); //true
    W.isNaN(1312); //false

    isFalsey:

    Even checks for empty object and array.

    W.isFalsey(false); //true
    W.isFalsey(null); //true
    W.isFalsey(0); //true
    W.isFalsey(""); //true
    W.isFalsey("   "); //true
    W.isFalsey({}); //true
    W.isFalsey([]); //true
    W.isFalsey(undefined); //true
    W.isFalsey(NaN); //true
    W.isFalsey(["", null, 0, NaN, undefined, , false]); //true

    isEmpty:

    Same as isFalsey but it returns false for false and 0. This helps to check required fields

    W.isEmpty(false); //false
    W.isEmpty(null); //true
    W.isEmpty(0); //false
    W.isEmpty(""); //true
    W.isEmpty("   "); //true
    W.isEmpty({}); //true
    W.isEmpty([]); //true
    W.isEmpty(undefined); //true
    W.isEmpty(NaN); //true
    W.isEmpty(["", null, 0, NaN, undefined, , false]); //false

    trim:

    W.trim("          "); //""
    W.trim("    hello   "); //"hello"
    W.trim(["", null, 0, NaN, undefined, false, , "hello"]); //["hello"]

    prefixInArray:

    W.prefixInArray(["Hello", "Hola", "Welcome"], "H"); //["Hello", "Hola"]
    W.prefixInArray(["Hello", "Hola", "Welcome", null, undefined, 0, false, NaN], "H"); //["Hello", "Hola"]);
    W.prefixInArray(["Wello", "Wola", "Welcome", null, undefined, 0, false, NaN], "H"); //[]
    W.prefixInArray(["Hello", "Hola", "Welcome"], undefined); //["Hello", "Hola", "Welcome"]
    W.prefixInArray(null, undefined); //null
    W.prefixInArray(["Hello", "Hola", "Welcome"], ""); //["Hello", "Hola", "Welcome"]
    W.prefixInArray(["Hello", "Hola", "Welcome",["Hello"]], "H"); //["Hello", "Hola"]

    sufixInArray:

    W.sufixInArray(["Hello", "Hole", "Welcome"], "e"); //["Hole", "Welcome"]
    W.sufixInArray(["Hello", "Hole", "Welcome", null, undefined, 0, false, NaN], "e"); //["Hole", "Welcome"]
    W.sufixInArray(["Wello", "Wola", "Welcome", null, undefined, 0, false, NaN], "H"); //[]
    W.sufixInArray(["Hello", "Hola", "Welcome"], undefined); //["Hello", "Hola", "Welcome"]
    W.sufixInArray(null, undefined); //null
    W.sufixInArray(["Hello", "Hola", "Welcome"], ""); //["Hello", "Hola", "Welcome"]

    findInArray:

    W.findInArray(["Hello", "Hola", "Welcome"], "el"); //["Hello", "Welcome"]
    W.findInArray(["Hello", "Hola", "Welcome", null, undefined, 0, false, NaN], "el"); //["Hello", "Welcome"]);
    W.findInArray(["Wello", "Wola", "Welcome", null, undefined, 0, false, NaN], "z"); //[]
    W.findInArray(["Hello", "Hola", "Welcome"], undefined); //["Hello", "Hola", "Welcome"]
    W.findInArray(null, undefined); //null
    W.findInArray(["Hello", "Hola", "Welcome"], ""); //["Hello", "Hola", "Welcome"]

    for

    does for in loop and checks for hasOwnProperty for both objects and arrays in one line.

    W.for([1, 2, 3, 4], function(index, item, items) {
      //do something
    });
    W.for({"key": "value"}, function(index, item, items) {
      //do something
    });
    W.for(undefined, function(index, item, items) {
      //do something
    }); //throws an error 'Unexpected type'
    W.for(undefined, undefined) // returns undefined
