> Lazily Evaluates Arrays via a function that is called on-read of an array's value 


## Install

```
$ npm install --save lazy-eval-array
```


## Usage

```js
const lazy = require('lazy-eval-array');

const arr = lazy( [ 0, 1, 2, 3, () => 4 ] )
arr[3]// => 4

const arr = lazy( [ 0, 1, 2, 3, function() {return this.x} ], { x: 20 } )
arr[3]// => 20 

const arr = lazy( [ (index)=>index, 1, 2, 3, (index,input1,input2)=>input1+input2 ], null, 10, 3 )
arr[0]// => 0
arr[3]// => 13
```


## API

### lazyEvalArray(input, ctx,[ arg1,arg2,argN... ])

#### input

Type: `Array`

The array that is being lazily evaluted.

#### ctx

Type: `Object`

This is the context in which the function will be run in. A.K.A what this will be when the function is run.

##### ags(1-N)

Type: `Anything`

These are the parameters that the inner function is called with. The first parameter that is called if the current index. Meaning the function signature is:
`function (current Index, args1, args2, argsN)`

### lazyEvalArray.noMemoization(input, ctx,[ arg1, arg2, argN... ])

Same as above but would not memoize the output of the function ran

### lazyEvalArray.promisify(input, ctx,[ arg1, arg2, argN... ])

Resolves all values as promises normalizing output of each function as well as each value

### lazyEvalArray.promisify.noMemoization(input, ctx,[ arg1, arg2, argN... ])

Same as above but will not cache the output of the functions ran
