In-memory polyfill for local storage

Add to your project:

`npm i local-storage-poorlyfill`

```html

// use _localStorage

```

### Why?

- For local files, IE and Edge do not have support for local storage

- local storage can be disabled

### Tested browsers

- Chrome, Firefox, Internet Explorer, Edge, Safari and Opera

### Implementation details

- Use browser's native implementation if supported

- Mirror native functionality with an object

### Implementation flaws

- Not persistent

- Need to use `_localStorage` instead of `localStorage`

### Scripts

Lint with standard:

```

yarn lint

```

Transpile with babel:

```

yarn build

```

Run unit tests:

```

yarn test

```

Use `_localStorage` or `window._localStorage` instead of `localStorage` or `window.localStorage` because the browser prevents using `localStorage` or `window.localStorage` if access is denied for this document.
