def change(implicit ticket: CreationTicket): Event[Diff[T]]

Create an event that fires every time the signal changes. It fires the tuple (oldVal, newVal) for the signal. Be aware that no change will be triggered when the signal changes to or from empty

def now: T

Returns the current value of the signal However, using now is in most cases not what you want. It does not build dependencies, does not integrate into transactions. Use only for examples and debug output.
