# memoize decorator

This is a method/getter decorator which is when applied to a method or a getter

memoizes the result of the first call and returns it on subsequent calls.

As decorators are a part of future ES7 standard they can only be used with

transpilers such as [Babel](http://babeljs.io).

Installation:

    % npm install memoize-decorator

Example:

```js

import memoize from 'memoize-decorator'

class Component {

  @memoize

  get expensiveValue() {

    console.log('heavy computations')

    return 42

  }

}

let component = new Component()

component.expensiveValue // prints 'heavy computations', returns 42

component.expensiveValue // just returns 42

```
