dom_id helper method:

The dom_id used here is basically a record identifier helper in Rails to associate records with the DOM elements.

Following is the brief example how it works:
```
dom_id(Post.new)         # => "new_post"
dom_id(Post.find 42)     # => "post_42"
```
Read more about dom_id in ActionView::RecordIdentifier documentation.

time_ago_in_words helper method:

It is the Date helper method which return the friendly message of time/date.

Following is the brief example how it works:

time_ago_in_words(3.minutes.from_now)                 # => 3 minutes
time_ago_in_words(3.minutes.ago)                      # => 3 minutes
time_ago_in_words(Time.now - 15.hours)                # => about 15 hours
time_ago_in_words(Time.now)                           # => less than a minute
