ChangeDetectionStrategy - Default

This is the default mechanism that Angular implements--changes are triggered by events and the propagation of changes goes from the view template to the model. Based on the logic implemented, the DOM structure is updated.

An important thing to note here is that using this strategy, every time Angular will traverse through all the components starting from the root component to the last component for checking if the properties have to be updated throughout.

Refer the example we created in preceding section, Implementing change detection in Angular. We are updating the properties and Angular by default uses the ChangeDetectionStrategy with the Default value.
