# easy-app

This library suggests programming model with the same
core idea as found in DI containers and build systems like make.
However here we refine the definition of typical container to
allow much more effective and broad usage.

## Programming model

Application (or any complex function) is described as a set
of global names, where the value of each name can be defined in following 3 ways:

  * As a constant
  * As a function, which can accept as arguments values of other names
  * As a level (A tuple of main value and a list of seeds)

The definition above is best made clear by an example.

```javascript
const App = require('easy-app')

let app = new App

app.def('a', () => 'a')

app.def('ab', (a, b) => a + b)

app.level('Ab', 'ab', ['b'])

app.def('abc', (Ab, c) => Ab('BB') + Ab('bb') + c)

app.level('Abc', 'abc', ['c'])

let abc = app.compile('Abc')

abc('C') // => 'aBBabbC'
```
