Why is the object not being removed from the array?

Question

Vue.js

Hi all!
there is a mutation

[types.REMOVE_FROM_CART] (state, { id }) {
        state.lastCheckout = null
        const record = state.added.find(p => p.id === id)
        if (typeof record == 'object')
            if (record.quantity == 1) {
                state.added.remove(record)
            } else {
                record.quantity--;
            }

when the number is greater than 1, then this branch works fine, i.e. decreases by one, but when it is equal to one and you press delete, it throws an error:
Uncaught TypeError: state.added.remove is not a function
Am I deleting somehow wrong?

Answer 1

state.added = array? then you can do this:

if (typeof record == 'object') {
    if (record.quantity == 1) {
        let i = state.added.findIndex(p => p.id === id);
        state.added.splice(i,1);
        //state.added.remove(record)
    } else {
        record.quantity--;
    }
}
