— Is someone here used to react - redux and can help me?


I have a form with multiple inputs each input subscribes the store and onChange updates the state which then gets saved in the localStorage. Every input is controlled and gets the value from the state. Problem when I type something in the form every input rerenders

— Uhm

— Wat

— You want to wrap an object in an array?

— Why?

— Coz the map function will take an array and I am receiving a json object

— Use the callback to map instead?

— Instead of:
Just do:

— Is your json already an array of objects? Then u can just do

JSON.parse(JSON.stringify(json)).map((obj) => console.log(obj));
