You're probably right about Elm which is basically one big reducer, but Redux adds a whole lot more indirection on top of that which makes it much more complicated. Even small Redux apps can start off with a lot of indirection as soon as they extract logic into selectors. This is probably the first area where Redux becomes more complex that what you were doing before: https://redux.js.org/usage/deriving-data-selectors https://redux.js.org/usage/deriving-data-selectors It reminds me of reading a bunch of parser combinators: it feels like you're reading code that builds something that does what you want instead of the code that just does what you want. const makeSelectItemsByCategory = () => { const selectItemsByCategory = createSelector( [state => state.items, (state, category) => category], (items, category) => items.filter(item => item.category === category) ) return selectItemsByCategory }
