Usage

Example

var is = require('simply-is');

is.object({}); 			//true
is.a.string('hello')	//chaining
is.not.an.array({})		//negation

//alternative syntax
is(3).even
is('hello').a.string
is('[{"key":"somevalue"}]').json

Basics

is.argument 	( (function(){ return arguments; })(1,2,3) )
is.array 		([1,2,3])
is.boolean 		(1==1)
is.date 		(new Date())
is.defined 		(1)
is.function 	(function(){return 'hi'})
is.json 		('[{"key":"somevalue"}]')
is.null 		(Null)
is.number 		(1)
is.object 		({})
is.regexp 		(/abc/)
is.string 		('hello world')
is.undefined 	(undefined)

Utility

is.empty		({}) 	//true for {}, [], 0, "", null, undefined, false
is.equal 		( {a: 1, b: "hello"}, {b:"hello", a:1} )
is.sameType 	({	a: 1, b: "hello" }, { a: "number", b: "string" })

is.inArray 		('a',['a','b','c'])

is.inObject 	('apple',{fruit: 'apple'})
is.inObject 	('fruit',{fruit: 'apple'})

is.instanceOf 	( doberman, DogConstructor )

Contains/inside

is.inside("fred", {"user": "fred", "age":40 })
is.inside("age", {"user": "fred", "age":40 })
is.inside("apple",["peach","apple","grapes"])
is.inside("cat","I love cats")

is("fred").inside({"user": "fred", "age":40 })
is("age").inside({"user": "fred", "age":40 })
is("apple").inside(["peach","apple","grapes"])
is("cat").inside("I love cats")

Numbers

is.number		(1)
is.nan			(NaN)
is.infinite		(Infinity)
is.even			(2)
is.odd			(3)
is.integer 		(10)
is.decimal 		(10.5)
is.numberValid 	(Infinity) //returns false for Infinity, -Infinity, NaN, and non-numbers
is.numberInvalid (NaN) //true. opposite of is.numberValid

Booleans

is.boolean  	(true)
is.true			(1==1)
is.false		(1==2)

Patterns

is.email 		('test@test.com')
is.phone 		('626-123-4567')
