Curried function deriving new array values by applying provided function to each item/index of provided array then applying `concat` to the results. Fast and compatible with modern or old browsers.
npm install array-mapcatconcat to the results. Fast and compatible with modern or old browsers.  
``shell`
npm install array-mapcat --save
> You can also use Duo, Bower or download the files manually.
###### npm stats
  
- Similar to [].concat.apply([], [].map()) but more functional and compositionally friendly.
- Optionally, a dot-notation formatted string may be provided for item property access.
###### Basic
`js
var mapcat = require('array-mapcat')
var splitword = (sentance) => sentance.split(/\s+/)
var sentences = [ 'two birds', 'three green peas' ]
mapcat(splitword, sentences)
//=> ['two', 'birds', 'three', 'green', 'peas']
`
###### Dot-notation object access
`js
var mapcat = require('array-mapcat')
var listmodel = [
{ list: [1, 2, 3] },
{ list: [4, 5, 6] },
{ list: [7, 8, 9] }
]
mapcat('list', listmodel)
//=> [1, 2, 3, 4, 5, 6, 7, 8, 9]
`
###### Pointfree Style
`js
var mapcat = require('array-mapcat')
var listmodel = Promise.resolve([
{ list: [1, 2, 3] },
{ list: [4, 5, 6] },
{ list: [7, 8, 9] }
])
listmodel.then(mapcat('list'))
//=> [1, 2, 3, 4, 5, 6, 7, 8, 9]
`
