Question

How do you list all properties of an object?

Answer 1

You can use the Object.getOwnPropertyNames() method which returns an array of all properties found directly in a given object. Let's the usage of it in an example,

const newObject = {
  a: 1,
  b: 2,
  c: 3,
};

console.log(Object.getOwnPropertyNames(newObject));
["a", "b", "c"];
