Problems naming vars in JS [duplicate]

I’m new to JS so I’m not sure if what I want to do can actually works but I hope someone could help.

Here’s what I did

let name = "couch " + i;

It’s in a loop and the idea is I’d like to do something like this

let name = new Couch(....)

I understand that what this does is just replacing the content of var name, but what I’d like is to use the content of my var name as a name for a new item

So, at the end I should have a new item created for each iterations, named couch 0, couch 1, couch 2 and so on utils my loop is over
