Felt the same way when I found out about it.
You can chain it together many times AND you can do nicer looking deep undefined checks
‘niceobj && niceobj.maybeUndefined && niceObj.maybeUndefined.functionOrValue’
Way cleaner than if statements, but not as clean as typescripts “?.” operator
Sorry for the poor formatting. On mobile.
Oh I just found out the “?.” operator might be coming to JS too and it’s already in Babel.
I highly encourage you to take a look!

Interesting. Thank you for letting us know.
It's not "might"; it's in stage 4 and will be added in ES2020.
Even better!
It's a good thing I read this article because if I had ever came across this I would have wondered what it was.
