localStorage.clear(); // removes everything from store

Support

Tested in these browsers:

• IE >= 10
• Chrome 48+

 Known limitations

Cookie and memory storage polyfills currently don't support the full behavior of native implementations.

Given this, these way of using the library currently is not supported:

const { localStorage } = require('fa-storage');

localStorage.something = 'asdf'; // storing a key value
localStorage.something // getting the value
