property 's arguments are getx, setx, delx and a doc string. In the code below property is used as a decorator. The object of it is the x function, but in the code above there is no place for an object function in the arguments.
So simply reducing the property check to typeof this[property] or, even worse, x.key will give you completely misleading results. It depends on what you're looking for. If you want to know if an object physically contains a property (and it is not coming from somewhere up on the prototype chain) then object.hasOwnProperty is the way to go.
How do I check if an object has a specific property in JavaScript?
Is the annotation @JsonProperty required here? What is the advantage of using it? I think I can remove this annotation without causing any side effects. Reading about this Jackson Annotations I don't know when this is required to be used ?
When is the @JsonProperty property used and what is it used for?
Descriptors like property need to be in the type's dictionary to work their magic. So those in a class definition primarily affect the behaviour of instances of the class, with minimal effect on the behaviour of the class itself (since the class is the type of the instances).
In my situation I had my property auto initialize a command in a ViewModel for a View. I changed the property to use expression bodied initializer and the command CanExecute stopped working.
How do I create a function to sort the objects by the price property in ascending or descending order using JavaScript only?
