Signal values can be updated using the set or update methods. When updating signal values, it's crucial to follow immutable practices.

Key points to keep in mind:

  • Use the set method for updating primitive values like strings or numbers
  • Use the update method with a callback that returns a new object or array when updating complex values
  • Avoid mutating signal values directly

Failure to follow immutable practices can result in stale data being displayed in the template.
