Tutorial on comparing two arrays Let's talk about comparing two array against each other and returning values that they have in common or values that they don't.

Eventually I found this neat solution and honestly I am not completely sure if I would get to it myself since I haven't been working enough with objects or this type of statement. Therefore, I will be going back to basics and I am planning to go through the Statements section on MDN. The solutions By using For In... statement we can solve both problems and I am still trying to figure out if it's possible to apply For Loop in the unique values function. Return common values I used here a For Loop on both vowels and str arrays (string becomes an arr...
