let cloning variable instead of modifying original

[fallen stag]

I have an array of objects which contain a count variable, when I use

let ingredientCount = userItems.find(item => item.objectId == recipeIngredients[ingredient].item)?.count
                        ingredientCount -= recipeIngredients[ingredient].count;

the actual count in userItems doesn't get changed, the ingredientCount one does instead. any possible fixes or workarounds?

don't extract out the count property, you need to mutate the object

let ingredient = userItems.find(item => item.objectId == recipeIngredients[ingredient].item);
ingredient.count -= recipeIngredients[ingredient].count;

oh looks like that's a naming conflict

eh, you'd have to solve that either way

okay

thank you :D
