* Remove redundant initial of isArray (#21163) * Reapply prettier * Type the isArray function with refinement support This ensures that an argument gets refined just like it does if isArray is used directly. I'm not sure how to express with just a direct reference so I added a function wrapper and confirmed that this does get inlined properly by closure compiler. * A few more * Rename unit test to internal This is not testing a bundle.
