Deprecated in favour of issimoteam/deep-state

A simple state store. Performs a deep comparison before calling the callbacks.

const state = State();

const cleanup = state.subscribe((prev, next) => {
  // stuff
});

state.value = { foo: "bar" }; // trigger callback
state.value = { foo: "bar" }; // nothing
