var a = []

/**
  Intended for high performance by looping an array only once but performing multiple actions.
  Run multiple functions for each iteration of an array.

*/
ack.array(a).each(method0, method1, method2, method3)

ack.array.distinct

ack.object.getTypeMap()

Crawls any variable type to generate a map of types

var v = {
  a:1,b:2,

  },
  agency:[{
    name:'My Agency'
  },{
    name:'Toast',
    email:'fake@aol.com',

  a: 'number',
  b: 'number',
  c: { c0: 'number', c1: 'string' },
  agency: [{ name: 'string', email: 'string', active: 'number' }]
}

//Example B
ack.object(v).getTypeMap(function(type, subs, key){

      "c0": {
        "type": "number",
        "subs": null
      },
      "c1": {
        "type": "string",
        "subs": null
      }
    }
  },
  "agency": {
    "type": "array",
    "subs": {
      "type": "object",
      "subs": {
        "name": {
          "type": "string",
          "subs": null
        },
        "email": {

          "subs": null
        },
        "active": {
          "type": "number",
          "subs": null
        }
      }
    }
  }
}

More Examples

Simple Example of Variable Exposing

//get date object for the first hour, minute and second of the first day of month
var aDate = require('ack-x').ack.date().now()
var startOfDate = aDate.gotoFirstDayOfMonth().gotoStartOfDate()
var monthStartsExactlyAt = startOfDate.date

console.log( monthStartsExactlyAt )

Complex Example of Variable Exposing

In the following example, many modules are used to manipulate variables

var ack = require('ack-x').ack
var xDate = ack.date().now()//expose date as now

ack.promise(
  xDate.getNextYear(),//promise val0 is next year as number
  xDate.nextYear(2).year(),//promise val1 is the year as number, in two years
  xDate.getNextYear(3)//promise val2 is the year as number, in two years
)
.then(function(y0, y1, y2){
  return y0 < y1 && y1 < y2
})
.if(false, function(){
  return 'Time is going in reverse'
})
.if(true, function(){
  return 'Time is going in correct direction'
})
.then( ack.string )//The promise string value, is injected into the string variable exposer
.call('toBase64')//The exposed string variable is casted to base64
.then( console.log )//log results of base64
.catch(function(e){
  console.log(e)
})
