= Resetable
A sweet to define temporary values and clear them off conditionally

== Setup
[source, bash]
----
npm i --save resetable
----

== Usage
[source, javascript]
----
const Resetable = require('resetable')
const name = new Resetable('defaultValue')
----

== What is this?
You all love creating chainable functions, which set global value and once to use that global, you clean it off. Okay wait! Let's check the below example.

=== Without Resetable

[source, javascript]
----
const carStore = {}
let carModel = null
let carType = null

carStore.model = (model) => {
    carModel = model
    return carStore
}

carStore.type = (type) => {
    carType = type
    return carStore
}

carStore.search = () => {
    const model = carModel
    const type = carType
    carModel = null
    carType = null

// perform search
}

carStore
    .model('1990')
    .type('stang')
    .search()
----

=== With Resetable

[source, javascript]
----
const Resetable = require('resetable')

const carStore = {}
let carModel = new Resetable(null) <1>
let carType = new Resetable(null)

carStore.model = (model) => {
    carModel.set(model) <2>
    return carStore
}

carStore.type = (type) => {
    carType.set(type)
    return carStore
}

carStore.search = () => {
    const model = carModel.pull() <3>
    const type = carType.pull()

// perform search
}

carStore
    .model('1990')
    .type('stang')
    .search()

<1> Define the temporary variable as resetable with a default value.
<2> Make use of the `set` method to set the value.
<3> Calling the `pull` method will clear the resetable variable back to the original value.
