Trigger

Trigger defines a name that will trigger the animation. Trigger names help us identify which trigger should be triggered based on events.

The general syntax to define a trigger is as follows:

trigger('triggerName', [  we define states and transitions here])

In the preceding code syntax, we are defining the following:

1. Trigger is defined by passing a mandatory parameter, the name and optional parameters, which can include state and transition.
2. Trigger name; we define a name to identify the trigger.
3. Optionally we can also define our states and transitions as parameters in the trigger definition.
