SyntaxError: Unexpected token '?'

Hi! I’m attempting to use this on my Sapper project. I’m new to Svelte, so let me know if this is a dumb mistake.

I can’t seem to get this package to run without getthig the following error in my terminal:

[0] /www/public/sapper/osprey-sapper/site/__sapper__/dev/server/server.js:5694
[0]   const json = typeof(localStorage) != 'undefined' ?? localStorage.getItem(key);
[0]                                                     ^

My stores.js looks like this

import { writable } from 'svelte-local-storage-store'

export const theme = writable('theme','dark')

And then, once I drop this code in my component, is when I get the error

<script>
  import { theme } from '../../stores'

  ...

<div>{$theme}</div>

I reverted to using a regular conditional, and confirmed it’s working with the sveltejs/template. Update svelte-local-storage-store version to 0.1.3 and let me know if it’s still an issue.
