code_baseline::rules::ast::prefer_use_reducer

Struct PreferUseReducerRule

pub struct PreferUseReducerRule { /* private fields */ }

Expand description

Flags React components that have too many useState calls.

When a component accumulates many independent useState calls, it often means the state values are related and would be better modelled as a single useReducer. The threshold is configurable via max_count (default 4).
