That’s a limit of your language, not Replit

No, it is supported in nodeJS.

I think I discovered the issue. I believe the “lite” version is not supporting it.
Once I signed up and setup my own replit, it works fine.

Thanks.

Possibly you were using an outdated version of Node

Thanks, but no.

Using this link… https://replit.com/languages/nodejs
and selecting Node.js I get this error…

/home/runner/req7g76hjf9/index.js:2
let exist = obj?.a?.z
^
SyntaxError: Unexpected token ‘.’

However, once I signed up and used my accounts replit, it worked as expected and I got this result…

undefined

Here is the code…

let obj = {“a”: 1, “b”: 2}
let exist = obj?.a?.z
console.log(exist)

That line was the only thing in your file?
