使用这8个javascript库，可以更好地处理本地存储！！

localforage.setItem(‘name’, ‘Amy’, function(error, value) {

  // Do something

});

localforage.getItem(‘name’, function(error, value) {

  if (error) {

    console.log(‘an error occurs’);

  } else {

    // Do something with the value

  }

});

let storage = crypto;

let book = { title: ‘JavaScript’, price: 13 };

storage.set(‘book’, book, function(error, results) {

  if (error) {

    throw error;

  }

  // Do something

});

storage.get(‘book’, function(error, results) {

  if (error) {

    throw error;

  }

  // Do something

});
