Usage

You could fetch de module via require() if it's available. Otherwise, global fallback will be used, exposed via lil.type

var lil = require('lil-type')

Type checking

lil.isObject({}) // -> true
lil.isArray([1,2,3]) // -> true
lil.isNumber(1.2) // -> true
lil.isBool(1.2) // -> true
lil.isRegExp(/[a-z]/) // -> true

Content checking

lil.isEmpty(void 0) // -> true
lil.isEmpty('') // -> true
lil.isEmpty([]) // -> true
lil.isEmpty({}) // -> true
lil.isEmpty(1.5) // -> false
lil.isEmpty(new Date) // -> false

Getting data type

lil.is('name') // -> 'string'
lil.is({}) // -> 'object'
lil.is([1]) // -> 'array'
lil.is(/[a-z]/) // -> 'regexp'
lil.is(function () {}) // -> 'function'
lil.is(void 0) // -> 'undefined'

Type handle helpers

lil.isIterable([1,2,3]) // -> true
lil.isIterable({ name: 'Chuck' }) // -> true
lil.isIterable(function () {}) // -> false
lil.isIterable(true) // -> false
lil.isMutable({}) // -> true
lil.isMutable([]) // -> true
lil.isMutable('') // -> false
lil.isMutable(/[a-z]/) // -> false
