Validate if string is part of an array `.oneOf(string[])`

Maybe change the name for enum ?

👍 oneOf

[sindresorhus]

👍 Good idea

[SamVerschueren]

Why? Enums are not the same as arrays. Can you give an example?

[poupryc]

for me, enum refers to the possible value that can take the string. Or I did not fully understand the use cases of "is"

[transitive-bullshit]

I think enum would make more sense if it were the type, not the function. And since enums don't exist as a native type in JS, @SamVerschueren's OP suggestion seems the most consistent to me.

[SamVerschueren]

Exactly, enums are more a TS thing rather than a JS thing.

[poupryc]

Yes, it might be confused. "in" seems fine in this case ^^

Alternatively, oneOf might be a little clearer and it follows react's prop-types naming.

ow(input, ow.string.oneOf(['foo', 'bar']));
