The idea behind the example

Use CerebralJS to manage an apps state and side effects in a declarative manner:

Declarative CerebralJS:

[
  setLoading(true),
  getUser,
  {
    success: setUser,
    error: setError,
  },
  setLoading(false),
];

vs imperative JS:

function getUser() {
  this.isLoading = true;
  ajax
    .get("/user")
    .then(user => {
      this.data = user;
      this.isLoading = false;
    })
    .catch(error => {
      this.error = error;
      this.isLoading = false;
    });
}
