What is one purpose of a customer data JS library?

The customer data JS library is used to store private customer data in local storage. This data can be

used to improve the customer's experience on the store, such as by remembering their shipping

address or their preferred payment method.

The customer data JS library in Adobe Commerce is used for managing customer data on the client

side, such as the shopping cart, comparison list, and wishlist. It does not store sensitive information

like credit card details or usernames and passwords. Instead, it utilizes local storage to keep a private

data section where customer-specific data is stored securely and accessed via JavaScript, making

option B correct.
