Adds a different warning message for multiple arguments supplied to oneOf. A common mistake is to write oneOf(x, y, z) instead of oneOf([x, y, z]) and this should help developers identifying the error.

Why is it better to warn here, and not throw an error? Wouldn’t that surface it most rapidly?

I totally agree - it's my first contribution to prop-types so I'm being cautious here. I didn't want the output of neither oneOf('red') nor oneOf('red', 'blue') to change, as this may be considered breaking by some. So I just "enhanced" an error message in one of the cases.

Thanks for reviewing @ljharb. Force pushed to squash and change the unit tests to remove "instance of" from the strings you've changed. |
