Tell us what’s happening:
Describe your issue in detail here.
I don’t understand why my collection[i].property is undefined. When I console.log the property, it is either first or last for this test case which means collection[i].property should be property[i].first and it should give the value for it but all I see is undefined. Any help would be greatly appreciated!
**Your code so far**
function whatIsInAName(collection, source) {
const arr = [];
// Only change code below this line
for(let i = 0; i < collection.length; ++i) {
for (let property in collection[i]) {
console.log(collection[i].property);
if(collection[i].hasOwnProperty(property)) {
arr.push(property);
}
}
}
console.log(arr);
// Only change code above this line
return arr;
}
whatIsInAName([{ first: "Romeo", last: "Montague" }, { first: "Mercutio", last: null }, { first: "Tybalt", last: "Capulet" }], { last: "Capulet" });
