typical

typical

For type-checking Javascript values.

Example

var t = require("typical");

• typical
  • .isNumber(n) ⇒ boolean
  • .isPlainObject(input) ⇒ boolean
  • .isArrayLike(input) ⇒ boolean
  • .isObject(input) ⇒ boolean
  • .isDefined(input) ⇒ boolean

t.isNumber(n) ⇒ boolean

Returns true if input is a number

Kind: static method of typical

Param	Type	Description
n	*	the input to test

Example

> t.isNumber(0)
true
> t.isNumber(1)
true
> t.isNumber(1.1)
true
> t.isNumber(0xff)
true
> t.isNumber(0644)
true
> t.isNumber(6.2e5)
true
> t.isNumber(NaN)
false
> t.isNumber(Infinity)
false

t.isPlainObject(input) ⇒ boolean

A plain object is a simple object literal, it is not an instance of a class. Returns true if the input typeof is object and directly decends from Object.

Kind: static method of typical

Param	Type	Description
input	*	the input to test

Example

> t.isPlainObject({ clive: "hater" })
true
> t.isPlainObject(new Date())
false
> t.isPlainObject([ 0, 1 ])
false
> t.isPlainObject(1)
false
> t.isPlainObject(/test/)
false

t.isArrayLike(input) ⇒ boolean

An array-like value has all the properties of an array, but is not an array instance. Examples in the arguments object. Returns true if the input value is an object, not null and has a length property with a numeric value.

Kind: static method of typical

Param	Type	Description
input	*	the input to test

Example

function sum(x, y){
    console.log(t.isArrayLike(arguments));
    // prints `true`
}

t.isObject(input) ⇒ boolean

returns true if the typeof input is "object", but not null!

Kind: static method of typical

Param	Type	Description
input	*	the input to test

t.isDefined(input) ⇒ boolean

Returns true if the input value is defined

Kind: static method of typical

Param	Type	Description
input	*	the input to test
