Listen for State Changes

In Core Neuron state is not reactive out of the box as it is in JS frameworks/libraries like Svelte or React. It is up to the developer to make your state reactive. Neuron has a special method called effect. This method runs every time the Neuron is updated. It returns an updated payload object with state data every time it runs. You can run specific logic based on the payload or other data.

const pokemon = new Neuron("Pikachu");
const trainer = new Neuron("Ash");

pokemon.effect((payload) => {
  //This runs when pokemon has been updated.
  console.log(payload.state);
});

trainer.effect((payload) => {
  //This runs when trainer has been updated.
  console.log(payload.state);
});

The effect method can be used to connect Neurons to native state solutions in other JS frameworks. It is the reason Neuron is an "agnostic" global state manager.
