Working with objects - JavaScript

Inheritance and the prototype chain - JavaScript
also, when iterating over the properties of an object, every enumerable property that is on the prototype chain will be enumerated.

Object.entries() - JavaScript
(the only important difference is that a for...in loop enumerates properties in the prototype chain as well).

Object.prototype.propertyIsEnumerable() - JavaScript
this method can determine whether the specified property in an object can be enumerated by a for...in loop, with the exception of properties inherited through the prototype chain.

Object.values() - JavaScript
(the only difference is that a for...in loop enumerates properties in the prototype chain as well.) the source for this interactive example is stored in a github repository.
