Class Decorators:
Class decorators execute when the class they are applied to is defined. This occurs during the class declaration phase.
They run once for each class declaration, and their execution order is from the top to the bottom of the class definition.
Method Decorators:
Method decorators execute when the method they are applied to is defined within the class. This also occurs during the class declaration phase.
They run once for each method declaration.
Property Decorators:
Property decorators execute when the property they are applied to is declared within the class. Again, this happens during the class declaration phase.
They run once for each property declaration.
Parameter Decorators:
Parameter decorators execute when the method or constructor they are applied to is defined. This is still part of the class declaration phase.
They run once for each parameter within the method or constructor.
