foonyah.each(obj, fn)

Iterate the object ( including <Array> ) obj and execute the function fn for each value in the object. The key is give to 1st argument for the function fn and the value is given to 2nd argument. If return false, stop the iterating.

_

var f = window.foonyah;
var obj = { a: 1, b: 2, c: 3 };
f.each(obj, function(k, v) {
  console.log(k + ':' + v);
  return k != 'b';
});

// a:1 
// b:2

foonyah.isFunction(x)

Judge the type of x is <Function> or not.

var f = widow.foonyah;
var x = Function(), y = {}, z = [];
console.log(f.isFunction(x), f.isFunction(y), f.isFunction(z))

// true, false, false

_

var f = window.foonyah;
var x = Function(), y = {}, z = [];
console.log(f.isFunction(x), f.isFunction(y), f.isFunction(z))

// true, false, false

foonyah.isArray(x)

Judge the type of x is <Array> (NOT including <Object>) or not.

var f = widow.foonyah;
var x = Function(), y = {}, z = [];
console.log(f.isArray(x), f.isArray(y), f.isArray(z))

// false, false, true

_

var f = window.foonyah;
var x = Function(), y = {}, z = [];
console.log(f.isArray(x), f.isArray(y), f.isArray(z))

// false, false, true

foonyah.isPlainObject(x)

Judge the type of x is <key-value Object> (NOT including some instance, null) or not.

var f = widow.foonyah;
var x = Function(), y = {}, z = new Function();
console.log(f.isPlainObject(x), f.isPlainObject(y), f.isPlainObject(z))

// false, true, false

_

var f = window.foonyah;
var x =null, y = {}, z = new Function();
console.log(f.isPlainObject(x), f.isPlainObject(y), f.isPlainObject(z))

// false, true, false

foonyah.type(x)

Return the type of x with some extended type compare with JavaScript typeof.

f.typeof(undefined)	undefined
f.typeof(null)	null
f.typeof('ABC')	string
f.typeof(123)	number
f.typeof(function(){ })	function
f.typeof({})	object
f.typeof([])	array
f.typeof(new f.Emitter())	object

var f = widow.foonyah;
var x = Function(), y = {}, z = null
console.log(f.type(x), f.type(y), f.type(z))

// false, true, false

foonyah.is(type, x)

Judge the type of x equals type.
If x is an jQuery wrapped object, type is treated as an selector and returns jQuery.fn.is(type) result.

_

var f = window.foonyah;
var x = Function();
console.log(f.is('function', x), f.is('object', x), f.is('div', $('<div/>')))

// true, false, true

foonyah.noop(x)

Returns no-operation function. ( feature: with returns x or undefined. )

var f = widow.foonyah;
console.log(f.noop()());
console.log(f.noop(1)()); // next feature

// undefined
// 1

_

var f = window.foonyah;
console.log(f.noop()());
console.log(f.noop(1)()); // next feature

// undefined
// 1

foonyah.es6promise(x)

Wrap by Ecma Script 6 Promise if x is jQuery.Deferred object.

_

var f = window.foonyah;
var x = $.Deferred();

/* You can use Ecma Script Promise chain after the wrap.  */
f.es6promise(x.promise()).then(function(){
  return new Promise(function(rsl){
    setTimeout(rsl, 3000);
  });
})['catch'](fucntion(e){
  // error handling 
  console.log(e);
});

foonyah.jquerify(x)

Wrap by jQuery.Deferred if x is Ecma Script 6 Promise object.

_

var f = window.foonyah;
var x = new Promise(function(rsl){ setTimeout(rsl, 3000) });

// You can use jQuery.Deferred chain after the wrap.
f.jquerify(x).pipe(function(){
  return $.Deferred().resolve()
}).progress(function(){
  // some notification receiver
  console.log(arguments);
});

foonyah.funcStringify(fn, replace, options)

Convert a function fn to string with using word-map replace.

_

var f = window.foonyah;
var x = function() { console.log('a') }
console.log(f.funcStringify(x)); 

// console.log('a')
