Kata is now retired.

Thank you for your feedback! Fixed it.

Oh, I didn't think of that.

Even better, stick an Object.freeze(Math) in the preloaded.

How true, great catch.
Xièxiè!

it makes sense

fixed

Fully agree on the random tests, no discussion there.

But I think it's up to the author whether or not to restrict the kata to primitive types or not. If not, how to count unprimitives is the next decision - by constructor, by typeof, or all of 'em as objects. Whichever way, it should be specified ( and that can be as simple as adding "the given array will contain only primitive datatypes" to the description ). But it's a choice. ( Which may affect ranking. )

FIXED!

Yes, you can cheat.

Doesn't mean you should.

Closing.

Use a recursive random generator for the searchValue. It's slightly advanced, but it's not difficult.

Marking the suggestion as resolved; lack of random tests is really an issue.

Thanks, This is fixed now
