deraCoder:
Thanks…
Don't have to study all…you can learn the ones that are applicable to what you are doing as a dev

Agreed most might not be needed until you get to that stage.

OlawaleBammie:
Baba good evening sir

Pls I need an advice from u.

I just started learning software development sir, and my aim is this.. By the end of my study I want to move abroad (Canada) on a study route(degree in software engineering as well), pls is it possible for me to get an internship program over there while I study??

I can't say for sure, when I asked someone; their answer was yes, I guess it depends on the province

Devdevdev:
The videos is enough. Thank you so much

You have a nice voice.

Appreciate

@devdevdev how do I send the code, or is the video enough ?

truthCoder2:
Please what OS are you using?

I can see Mac OS-like buttons and a windows-lke tray

KUbuntu KDE Plasma but i downloaded a style called breeze, it has that mac-os feel

Fixed recording video to explain now

I don't understand the logic behind your code,

If you want to add to Cart, why not create an empty array, and only add when a payload matches, I will do it and share a video soon.

truthCoder:
cartItem.amount was undefined because it was not existing at initial state.

It was not existent because cartItems didn’t have an amount parameter in the objects.

You also called {amount} instead of {product.amount}. This was rightly pointed out by GIM above.

Defining amount in your objects would remove the need for ||0

Yeah that's right it's undefined

WIP

I noticed I made some mistake in my comments, I used combinedReducer, you used createSlice, createSlice handle the type and action on it's on, so the name + reducer function is triggered, look the screenshot your code works.

The payload is logged to the console, so the next part is to experiment with the Cart component and see if it reflects there

Devdevdev:
@qtguru, i took your adviced and pushed the two projects to github. You will find them on my github profile

https://github.com/devdevdev69

Awesome, let me clone

Did you push it to Github ? this can be solved faster if shared.

sqlPAIN:
if you really want to expand your knowledge or study computer science as you said,then take jamb this year,enter school and go get a CS degree. Stop deceiving ya sef oga

No comment

sqlPAIN:
All these just to get a high paying job abi?

No it's about studying Computer Science, if you are interested in expanding your knowledge

truthCoder:
Share the code repository

GitHub was invented for this reason.

Exactly taking too much time to fix a bug like this, we could have ironed it out with github.

Devdevdev:
Sent

This won't work, I don't have the package.json, you were supposed to send the whole project so I can install the modules and run on my end.

Devdevdev:
@GreatIgboMan, do you have an email address? I'll mail the code to you and qtguru now.

OKEOWOADEREMI AT GMAIL DOT COM

Devdevdev:
I tried implementing your instruction. Still didn't work.

Put a debugger and see if you reach the reducer, send the project to my mail, let me run it and fix. coding by looking at image is long thing.

Your code is wrong. Fix those issues I pointed out, A reducer should always return a new state always

2. your dispatch is meant to take an object , you also didn't change that too

Devdevdev:
I already did. Still same issue.

1. You didn't refactor the reducer to return a new state

Get rid of the Context, you're already using Redux Hooks, you don't need it. Just use only Redux, let each component query the reducer it needs.

[quote author=Devdevdev post=120165256][/quote]You are using useDispatch wrong, because your code won't know which reducer to call I think

Do this in your reducer. e.g return {...state, {amount: action.payload | value }} something like that

The value return becomes the new state, and triggers every component listening to that, allowing them to receive the new copy. Try my suggestion.

When you call a Dispatcher, it uses the type to know which reducer to call, it expects a return value, but you are doing a side-effect instead of returning something like this e.g
{...state,newProps}

This is how the Dispatch is, it requires a type, also the point of the reducer is to return a new object combined from previous state and new update. What you're doing is an impure function. Look at this code i uploaded.

also the item.id === payload what is that logic ?

Devdevdev:
I switched to redux tool kit and I am still having the same issue. The clearCart and removeItem functionality are working just fine. It's just the addOne that isn't. I think the issue is with the 'amount' variable and how it's state is getting altered. I am seriously confused.

want to jump on google meeting, it's hard to debug on image
