javascript – any type of ideas for shuffle the test?

This source I obtained from Google, I have actually attempted exactly how to make the test arbitrary however I really did not discover a great way to randomize the test.

Exists a simple means to randomize the test? I attempted making use of shuffle however it fell short, possibly since I’m still a newbie so I still do not have expertise.

occupy();.

I attempted if it was revitalized or responded to on it would certainly raise an arbitrary test.
