Danke you for the clarification

We're playing the code golf (https://en.wikipedia.org/wiki/Code_golf) game, tl;dr write a solution with the minimal number of characters. Yes, in real, production code, you'd use const or let (var is still valid, but most modern code uses let unless var is absolutely necessary, since it has slightly different behavior https://stackoverflow.com/a/11444416/12101554), but this is still valid JavaScript.

Use const, let or var!!!

Agreed, but sometimes practicing this type of coding style in easier task make it easy on harder tests with a max char length

Minified code is not optimal for reading ^_^

I love those as well. It's so interesting. I always look up what they're about if no one explained them in the replies. It's fun to know that those fancy options exist.

This is the kind of solution I adore in the easier kyu range. Not too wild, but wild enough to make me go, "ooooh."

I would say that's a bit messy syntax. Function should be declared at least with 'const' keyword.

Didn't know about that operator. Not anymore

In general - no.
For a 1-liner in isolated code runner - doesnt matter.
