Can't get values from input with Javascript

I had read some other articles trying to solve this problem but I still have the same problem: I can't obtain values from inputs. After I click the "Crear Cuenta" button it gives me 'undefined'. I expect to pass these values from inputs to a javascript file and then do some other stuff.

function registrar() {
  let nombre = document.getElementsByName("nombre").value;
  let apellido = document.getElementsByName("apellido").value;
  let username = document.getElementsByName("username").value;
  let email = document.getElementsByName("email").value;
  let password = document.getElementsByName("password").value;
  let confirmPassword = document.getElementsByName("confirmPassowrd").value;

  console.log("Pass: " + password);
  console.log("Confirm: " + confirmPassword);

  if (password != confirmPassword) {
    alert("Contraseñas No coinciden");
  }

  var usuario = [];
  usuario["nombre"] = nombre;
  usuario["apellido"] = apellido;
  usuario["username"] = username;
  usuario["email"] = email;
  usuario["password"] = password;

  console.log(usuario);
}

Two point need to pay attention:

  1. getElementsByName returns array instead of single element,so need to use let nombre = document.getElementsByName("nombre")[0].value

  2. Using confirmPassword instead of confirmPassowrd to get value(it's a typo)
