You can turn arrays into sentences!

There's a neat little method Array#to_sentence that turns your array into a string in sentence format.

It's pretty self-explanatory, so here are some examples:

superheroes = ["Spider-Man", "Batman", "Iron man", "Wonder woman"]

superheroes.to_sentence
=> "Spider-Man, Batman, Iron man, and Wonder woman"

superheroes.to_sentence(
  words_connector: " or ", 
  last_word_connector: " or maybe even "
)
=> "Spider-Man or Batman or Iron man or maybe even Wonder woman"

With slight configuration, you can even have this work in different locales. Check it out in the docs!
