What are some common mistakes with immutability in React?

What are some common mistakes with immutability in React?

One common mistake is directly mutating state instead of creating a new copy. This can lead to unexpected behavior.

Can you give an example of direct mutation?

Sure! For instance, using array.push() to add an item to a state array directly mutates the original array.

What should I use instead?

You should use methods like concat() or the spread operator to create a new array, like setArray([...array, newItem]).

Are there any tools to help with immutability?

Yes! Libraries like Immer can help manage immutability more easily by allowing you to write code that looks like you're mutating state.
