same here hahaha

Perhaps it is not necessary to convert p to be a string?

Thanks! Suddenly it works when I replace "\s" with a plain space. (But surely the more terrible thing is I need to figure out why it works. :p)

The problem is with how you're using "\s".

expected 'og bvfay bgwuwegua' to equal 'bgwuwegua bvfay go'
     Your answer  /\            expected answer /\

You have to reverse words longer than 4 characters. The description is quite clear, try to read it a few more times :/

I am using JavaScript and I have passed the sample test, but when I "attempt", it cannot pass. Some examples of the failed attempts:
expected 'og bvfay bgwuwegua' to equal 'bgwuwegua bvfay go'
expected 'vznggzimwujo ueygizjhwt pmmazmgcyopa' to equal 'pmmazmgcyopa ueygizjhwt vznggzimwujo'
expected 'hzrmlncyotc r' to equal 'r hzrmlncyotc'

Not sure if I have misunderstood the errors, it seems that I have to reverse the whole phrase by words (but not by letters)? But I cannot see such requirement in the instructions.

Hope to get some hints, thanks.
