This object property doesn't want to update?

I'm trying to change that property from a2 to a3:

const pieceKey = findPieceByPosition(allPieces, previousSelection);
const updatedPiece = {
...allPieces[pieceKey],
position: "a3",
};

alert(findPieceByPosition(updatedPiece, previousSelection)) /*undefined for some reason, thus no position: "a3"*/

const findPieceByPosition = (piecesArray, position) => {
for (const pieceKey in piecesArray) {
const piece = piecesArray[pieceKey]
if (piece.position == position) {
return piece
}
}
return undefined
}

piecesArray.find(p => p.position === position)

you're returning the actual piece but then treating it as a key. stop using arrays like objects.

I'm don't understand exactly where this fits, is this supposed to replace the findPieceByFunction?

[quick flame]

yes

[hybrid saddle]

ok so if i got you correctly p is for position, and will it provide the property key instead of the property key as an object?

...

let allPieces = {
w_pawn_1: { position: "a2", type: "pawn", color: "black", moved: "no" },

you need to rewind and address my other comment first

dafaq? allPieces isn't even an array?

why would you name the parameter piecesArray when it's an object?

[hybrid saddle]

yeah i forgot to change the name from it from when it was an array

i think it used to be or something

my bad
