Kata republished, all versions should be available. Anyway, in older versions you can use core-js, like require('core-js/fn/object/values').

Sorry for disappointing you but due to Node version differences Object.value is presently unavilable on Codewars. Please try using alternatives.

JS: Working with object just for practice. Added all vowels seperately within an object then tried counting values but states Object.value is not a function. It works fine in my terminal.
