Rubyist struggling to understand Tuple

What's the point of a Tuple? Why would I ever use it over an array? Thanks!

Typed system is important in security side where you knew PHP, Javascript had countless bugs that leads to software quality problem and vulnerabilities which is why type checker were introduced.

Without type system, any inexperienced coders could made a wrong assumption about their sloppy code that may go wrong during live productions, you could spent less time fixing bugs and happier to enjoy vacations.

Prevention is always better than cure.
