Why, "try and" could be like "try / finally", and "what all" could be filter().
I won't mind "await y'all" to await multiple promises.
What if...
try { let x = parseInt(input); and { displayResult(x / 0); } } catch { displayError("Parsing error.") }
What if...
And the catch can't catch a division by zero error because it occurred inside an "and" block.
