:) You're welcome!

Thanks! You could still use parseInt and parseFloat, or "+" depending on the use case (i.e. parsing strings with non-numerical characters vs. parsing hex values), but I find "+" convenient for working with TypeScript in general.

Here is a helpful table for reference:

*Lol at second glance it appears I accidentally flipped the params in reduce. Should be:
.reduce((acc, n) => acc + n)

My apologies dinglemouse -- I indeed made a mistake. Yes it was JavaScript -- thank you. And Thanks for putting words in my mouth FArekksu -- so helpful.

Many of the test cases are wrong, even after testing them against unlocked solutions.
