Understand Own Properties hasOwnProperty() problem

Tell us what’s happening:

Why in the example given in the explanation of the challenge use the hasOwnProperty() method? As far as I know, there is nothing to verify, we just want to store the object properties in an array, i.e. the hasOwnProperty() method is not necessary.

I would appreciate it if you could clarify this for me, thank you.

Your code so far

function Bird(name) {
  this.name = name;
  this.numLegs = 2;

let canary = new Bird("Tweety");
let ownProps = [];
// Add your code below this line
for (let prop in canary) {
