Merge 295fe153ad into 4f2399de13

Hello, I've added a small blockquote below the description to indicate that this method of accessing an indefinite number of function arguments has been superseded by the use of the spread operator via rest parameters for ES6+ compatibility.

+# Useful ActiveSupport Constants For Durations
+
+Whenever I'm passing a duration to a function, I like to [name it with the
+unit](https://ruudvanasseldonk.com/2022/03/20/please-put-units-in-names)
+relative to the value it represents. For instance, if I need to pass in an hour
+duration in seconds, I might write the following line:
+
+```ruby
+hour_in_seconds = 60 * 60
+
+# or
+
+hour_in_seconds = 3600
+```
+
+ActiveSupport has a [Duration
+class](https://api.rubyonrails.org/classes/ActiveSupport/Duration.html) with a
+series of constants that we can reach for.
+
+```ruby
+> ActiveSupport::Duration::SECONDS_PER_MINUTE
+=> 60
+> ActiveSupport::Duration::SECONDS_PER_HOUR
+=> 3600
+> ActiveSupport::Duration::SECONDS_PER_DAY
+=> 86400
+> ActiveSupport::Duration::SECONDS_PER_WEEK
+=> 604800
+> ActiveSupport::Duration::SECONDS_PER_MONTH
+=> 2629746
+> ActiveSupport::Duration::SECONDS_PER_YEAR
+=> 31556952
+```
+
+Though it is fun to know about these, we should keep in mind that this class
+provides support for what is likely to be a more useful abstraction layer:
+
+```ruby
+> 1.hour
+=> 1 hour
+> 3.hours
+=> 3 hours
+> 1.day.to_i
+=> 86400
+```
