# What is Modular

**Modularjs** is our custom modules reader to make pages, built specifically for Nexo Maker. Using Modularjs makes your pages are significantly more **dynamic** and **reactive** to changes.

Inspired heavily by **React.js**, Modularjs follows a similar component-based structure and supports hooks to manage state and side effects inside the app.

With Modularjs, you can:

* Run JavaScript functions on component render
* Store and modify global or session data
* Build interactive, stateful components that respond to user input
* Create modular, reusable UI elements

This approach empowers you to develop rich, reactive content inside Nexo Maker seamlessly.
