unnecessary code in the material?
the code i used is:
function Bird(name) {
this.name = name;
this.numLegs = 2;
}
let canary = new Bird("Tweety");
let ownProps = [];
// Only change code below this line
for (let property in canary) {
ownProps.push(property)
}
the code used in the learning material:
for (let property in duck) {
if(duck.hasOwnProperty(property)) {
ownProps.push(property);
}
}
why add the if statement?
