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.
Chemical kinetics, the branch of physical chemistry that is concerned with understanding how fast or how slow chemical reactions occur (that is, their rates). The principles of chemical kinetics apply to purely physical processes as well as to chemical reactions.
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.
