Agradecería un poco de ayuda con mi aplicación para tomar notas. Digamos que tengo 3 notas en mi lista de notas. Quiero eliminar la nota en la parte superior de la lista. No importa cuál trate de eliminar, siempre se eliminará primero la nota que esté al final de la lista. Revisé la consola React, y la matriz de notas en el estado del Componente de la aplicación dice que se eliminó correctamente. Pero en la vista en sí misma, no lo es. ¿Cómo puedo obtenerlo para eliminar la nota exacta que elegí?

                title: "",
                details: ""
            }
            this.updateTitle = this.updateTitle.bind(this);
            this.updateDetails = this.updateDetails.bind(this);
            this.submitHandler = this.submitHandler.bind(this);
            this.deleteHandler = this.deleteHandler.bind(this);

        }

        updateTitle(event) {
            this.setState({ title: event.target.value });
        }

        updateDetails(event) {
            this.setState({ details: event.target.value });
        }
