JavaScript array elements undefined

[BrionnaKittles]

Hi, I’m quite new to Coding and thus really new here so I’m sorry if I sound like a major newbie, I just can’t seem to figure out what I’m doing wrong here.
This is my code:

let listOfPuppies = ["Shadow, Mocha, Max, Marshmellow"];
console.log(listOfPuppies);

listOfPuppies [4] = "Sparky"
console.log(listOfPuppies)

For some reason, it prints out 3 empty items in the middle of the array and I can’t seem to figure out why, any help would be appreciated. Thank you!

Java !== JavaScript, they are two completely different languages.

let listOfPuppies = ["Shadow, Mocha, Max, Marshmellow"];
console.log(listOfPuppies);

listOfPuppies [4] = "Sparky"
console.log(listOfPuppies)

The issue with your code is that there is only one element in the array, so when you assign an element to index 4, the three elements between index 0 and 4 are undefined.

The reason there’s only one element in the array is because you haven’t closed the strings for each item. Try this:

let listOfPuppies = ["Shadow", "Mocha", "Max", "Marshmellow"];
