What is the difference between Object.keys and Object.getOwnPropertyNames?
An example of an AI chatbot conversation about the difference between Object.keys and Object.getOwnPropertyNames.
Can you explain the difference between Object.keys and Object.getOwnPropertyNames?
Sure! Object.keys returns an array of a given object's own enumerable property names, while Object.getOwnPropertyNames returns all own property names, including non-enumerable ones.
So, if I have an object with non-enumerable properties, will Object.keys show them?
No, Object.keys will only show the enumerable properties. If you want to see all properties, including non-enumerable ones, you should use Object.getOwnPropertyNames.
Can you give me an example of when to use each?
Certainly! Use Object.keys when you only need the properties that can be iterated over, like in a for...in loop. Use Object.getOwnPropertyNames when you need a complete list of properties, regardless of their enumerability.
