 To send requests from the storefront to the Medusa application’s Store API Routes, you have three options:
 
+- **For JavaScript frameworks**: use Medusa’s [JS SDK](../../js-sdk/page.mdx) in any JavaScript framework. This NPM package facilitates interacting with the backend’s REST APIs.
 - **For other frontend technologies**: interact directly with the Medusa application by sending requests to its [Store REST APIs](https://docs.medusajs.com/api/store).
-- **For React-based storefronts**: use Medusa React. It provides you with the necessary hooks to retrieve or manipulate data from your Medusa application.
-- **For JavaScript frameworks**: use Medusa’s JavaScript Client in any JavaScript framework. This NPM package facilitates interacting with the backend’s REST APIs.
