Why Number(symbol) crashes?

[medikoo]

I was searching available resources but wasn't able to find the answer.

What's the reasoning behind having Number(symbol) crash instead of returning NaN (as it's in the case all other non-coercible values that expose some primitive representation)? It feels not consistent.

If someone can point me to some discussion that provided the reasoning I'd be grateful.

I originally posted this question at Mozilla discussion group, but it feels a bit abandoned. If this repository is not right place for such questions, I'll be glad if you direct me to the right one. Thanks!

Number(value) calls the abstract operation ToNumber(value), which throws a TypeError when value is a Symbol.

Why do you want to cast a symbol value to a Number?

This doesn't appear to be an issue with the current specification, and as such is not appropriate for this repo. es-discuss or StackOverflow are good ways to get clarification on specification and language usage questions.

I didn't say I want to do that. I said that specification seems inconsistent in handling non-number coercible values, and I'm wondering what's the reasoning.

@domenic I thought http://esdiscuss.org/ is not longer a place where TC39 is involved. Anyway thanks for redirection
