Description

when starting with React, i got hit with the issue where i would return multiple elements per component. would be nice if this error shows up at the lint stage as well.

not totally necessary since react would error anyways.

Contributor guide

Research direction
Create a new ESLint rule that detects when a component returns multiple root elements. Refer to existing rules in the plugin for implementation patterns and add appropriate tests.
