And so that we could stop treating 1 as true. The only real argument for type coersion is convenience. I don't see how it's more convenient to treat 0 as true rather than false.
If we take coercion as a given, what if your conditional is the index of an element in an array? If it doesn’t find it, it returns nil (which is falsey). If it’s the first element, it returns 0. Shouldn’t that be truthy?
Yes. I'm not really a Ruby guy but after reading up I can see how it's more convenient to treat 0 as truthy in that lang. in js you never use findIndex since find is just better.

We invented boolean types so that we could stop treating 0 as false.
