Create Immutable State Easily !travis-ci

An utility to easily create immutable state for Redux

Usage

#### Primitive types
1. Define the State
``typescript
import { createState, StateObject } from 'immutable-state-creator'

const State = createState('User', {
name: 'my name',
age: 10,
languages: ['English'],
pets: List.of('cat'),
active: true,
})
`

2. Create initial state
`typescript
const initState = State.create()
`

3. Use getter to select value
`typescript
expect(State.get('age')(initState)).toBe(10)
expect(State.get('name')(initState)).toBe('my name')
`

4. Use setter to update a value
`typescript
const newState = State.set('age', 20)(initState)
expect(State.get('age')(newState)).toBe(20)
`

#### Toggle boolean value
`typescript
const initState = State.create()
expect(initState.active).toBe(true)
const newState = State.toggle('active')(initState)
expect(newState.active).toBe(false)
