OK, thank you, I see that adding this code: const entries = Object.entries(person) document.getElementById("demo3").innerHTML = "entries: " + entries; to my post results in printing all the object properties and values on the screen. The only thing that I cannot understand is why the `person.length` reports 2 when the length of the object is actually 3 (2 does not change if I comment out the line that ads the third property and converts the array to an object).

I was fiddling with „Accessing Arrays with Named Indexes“ section examples of the Javascript tutorial and run into a situation I cannot understand. In short, I create an array 'person', then add elements to the array by index, and then add a third element by name. According to the tutorial, this should convert the array to an object (see here: https://www.w3schools.com/js/js_mistakes.asp) . Instead, after this I can access the variable 'person' as both an array (with two elements) and an object (or rather, a person.age property of the object). typeof 'person' reports: object. var person = []; person[0] = "John"; person[1] = "Doe"; person["age"] = 46; Here is a link to the full test: https://www.w3schools.com/code/tryit.asp?filename=GHWDV13H8E0Z Could someone explain what is happening here?
