localStorage.setItem('myFirstKey', 'myFirstValue')
console.log(localStorage.getItem('myFirstKey'))
# myFirstValue

localStorage._deleteLocation()  # cleans up ./scratch created during doctest

JavaScript

if (typeof localStorage === "undefined" || localStorage === null) {
  var LocalStorage = require('node-localstorage').LocalStorage;

}

localStorage.setItem('myFirstKey', 'myFirstValue');
