The Object getOwnPropertyNames() method
Find out all about the JavaScript getOwnPropertyNames() method of the Object object
THE AHA STACK MASTERCLASS
Launching May 27th
Object.getOwnPropertyNames() returns an array containing all the names of the own properties of the object passed as argument, including non-enumerable properties. It does not consider inherited properties.
Non enumerable properties are not iterated upon. Not listed in for..of loops, for example.
To get only a list of the enumerable properties you can use Object.keys() instead.
Example:
const dog = {}
dog.breed = 'Siberian Husky'
dog.name = 'Roger'
Object.getOwnPropertyNames(dog) //[ 'breed', 'name' ]
