# Other possible features to implement

This book introduces one of the multiple ways to create a frontend framework that reacts to interactions.

Here's an exhaustive list of what could / should be implemented:

• children rendering
• managing lifecycle: the biggest problem with our implementation is How / When to fetch data?
• improving performances
• managing style encapsulation (shadow DOM and alternatives)
• dependency injection system

A part of this has been implemented in https://github.com/mfrachet/frontend-example/tree/master/framework
