QUESTION
That what I came at best so far:
...ANSWER
Answered 2021-Jun-12 at 11:36You get the error this.interval is not a function
because you are calling this.interval into componentDidMount, but that isn't necessary. The interval is already defined in the constructor and it starts in that moment.
To fix it, just remove componentDidMount
QUESTION
I am using redux to update an array of characters as a user types or erases it, so that when the user correctly types the entire phrase I can set a success flag.
So far when typing in characters the redux type SET_INPUT fires off and updates my state but unfortunately my REMOVE_INPUT doesn't seem to fire off but it does however reach the action.
My Reducer: import { GET_PHRASE, SET_LOADING, SET_INPUT, REMOVE_INPUT } from "../types";
...ANSWER
Answered 2021-Jun-11 at 13:18In your event handler you are not calling removeInput

Hello all. I have a small issue with a React Native Flatlist. It takes the items from Redux store, but when i try to update the amount, with redux as well it changes me the order of the list. Except in last item.
If you encountered similar issue let me know. Thanks in advance
So far i discovered that the increase and decrease functions in Cart Item changes the order of my array.
These are the components i'm using to render the list.
CART LIST
...ANSWER
Answered 2021-Jun-08 at 13:10In your reducer what you are doing is finding the item whose quantity is to be updated. Update its quantity and push
