You don't want to start a religious war between the people who believe zero is special, and the ones who believe it should throw an error if you pass a string, and the people who believe it should attempt to convert the string to an integer, and the people who believe you should either round or truncate when the parameter is a floating point number, and the people who disagree about which direction to round, and the people who can't agree whether you should truncate towards zero or negative infinity.

Isn't the parameter always floating point in Javascript? (which does mean a package like isOdd will have to incorporate some level of mysticism...)

Let the fight begin! It goes well with some popcorn.
I can understand how fundamental education teachers don't grasp modern Algebrism and believe that Math is formed by fundamental, sacred definitions. But programmers ought to know better.
And my favorite case - that zero is false. (!!0)
What is-odd does is to throw an exception if you pass anything that isn't a safe integer or a string representation of a safe integer. Otherwise it just returns n % 2 === 1 (after converting string to int if necessary)
