I don't quite understand what I have to do and what is wrong with my code. This is the question of the topic:
If you remember, arrays have a property in common with strings: they can both use .length. When you call .length on an array, it returns the number of elements that array has.
Under your existing code, log the number of elements in languages to the console.
Oops, try again. Make sure to log the number of elements the languages array has to the console.
