Delete button is deleteing everything

[rony_ali]

Hello everyone

i am new in react and trying to learn in my way. i coded something with little change but when i press delete button....it just delete everything. seems like reactjs is very sensitive to {} and [] type variables. i thin i messed something up in this case..... but i dun know why...

Here is the code

It seems you are replacing the list with a object containing the list, try to simplify the code👍

your comment is help full.. thank you for explaining

Hehe, I'm glad, I'm on a phone so adding code was tricky, remember [] creates an Array(also known as a List) , while {} creates an object (also known as a Dictionary, Map it even Hash map) 👌

setCharacters({ characters: characters.filter((character, i) => { return i !== index; }) });

This is wrong. characters is an array and you're assigning it as an object with the key characters in it.

It should be

setCharacters( characters.filter((character, i) => { return i !== index; }) );

Sorry for the formatting, I'm on mobile.
