    Use Internal Transitions in XState to Avoid State Exit and Re-Entry


    Transitions come in two varieties: "external" and "internal". By default, a transition is considered external. This means that a transition will exit the current state node, and enter the next state node (even if that state node is the state the machine is currently in). This exit/enter loop will trigger any actions that are set on the exit and entry properties.

    A transition can be set to internal, either through setting a . (dot) in front of the state node name (as we do in this lesson), or through setting the property internal to true on the transition object.

    When a transition is internal, it will not exit and enter the state node, which means that the actions in the exit/transition/entry loop will not be called.
