My solution?

This was another way I did it:

    addGuestToArray() {
        this.state.guests.unshift({
            name: this.state.pendingGuest,
            isConfirmed: false,
            isEditing: false,

        });

        return this.state.guests
    }

    addGuest(e) {
        e.preventDefault();

        this.setState({
            guests: this.addGuestToArray(),
            pendingGuest: "",
            })
        }

But here you are literally manipulating the state directly with unshift, then use the state to set it in setState. You should never manipulate the state directly?
