How to change state without crutches?

Question

React

There is a state :

state = {
    todos: [
      { id: 1, text: "Test", isSuccess: false },
      { id: 2, text: "Test 2", isSuccess: false }
    ],
    todosText: null
  };

How can I change the value of isSuccess of a certain object without crutches?

Answer 1

this.setState(({ todos }) => ({
  todos: todos.map((n, i) => i === index
    ? { ...n, isSuccess: true }
    : n
  ),
}));
