## Install

```

npm install --save lodash-ny-util

```

## Usage

```js

_.mixin(require('lodash-ny-util'));

```

## API

### mapToHeaders

Maps the first row to become the property names of every following row, returning a list of maps.

```js

_.mapToHeaders([['a', 'b'], ['c', 'd'], ['e', 'f']]);

//becomes [{a: 'c', b: 'd'}, {a: 'e', b: 'f'}]

```

### promise

Shorthand for using lodash functions with A+ Promise's `.then` function

```js

return Promise.resolve(thing).then(_.promise(_.indexBy)('name')))

```

```js

return Promise.resolve(thing).then(_.promise('indexBy')('name')))

```

```js

return Promise.resolve(thing).then(_.promise(_.indexBy, 'name')))

```

```js

return Promise.resolve(thing).then(_.promise('indexBy', 'name')))

```

### invertKeys

Takes an object that contains other objects, and flips the keys of the object and the inner object.

```js

_.invertKeys({a: {b: 'c', d: 'e'}, f: {g: 'h', i: 'j'}})

//becomes {b: {a: 'c'}, d: {a: 'e'}, g: {f: 'h'}, i: {f: 'j'}}

```

### listDeepObjects

Takes an object, and returns every object inside that object.

```js

_.listDeepObjects({a:{b:{c:{d:'e'}}, f:{g:{h:'e'}}}})

// becomes:

//  [

//    { b: { c: { d: 'e' } }, f: { g: { h: 'e' } } },

//    { c: { d: 'e' } },

//    { g: { h: 'e' } },

//    { h: 'e' },

//    { d: 'e' },

//  ]

```

Optionally takes a filter:

```js

_.listDeepObjects({a:{b:{c:{d:'e'}}, f:{d:{g:'e'}}}}, 'd');

//becomes [ { d: { g: 'e' } }, { d: 'e' } ]

```

```js

_.listDeepObjects({a: {type:'yarn'}, b: {c: {type:'sweater'}}}, function (obj) { return !!obj.type; });

//becomes [ { type: 'yarn' }, { type: 'sweater' } ]

```
