Hi!
About Lodash's forEach function, and Lodash in general…
I told you that it "abstracts away from you the chore (and complexity) of looping", so that you can focus on what really matters for your application: the collection you want to iterate through, and the piece of logic you wish to be applied for each item.
You use forEach like this:
// You first define "the collection you want to iterate through":
| require 'ostruct' | |
| # Tiny wrapper around (custom) delayed jobs. | |
| # @see https://github.com/collectiveidea/delayed_job | |
| # @see https://github.com/collectiveidea/delayed_job#custom-jobs | |
| # | |
| # Create a new job by inheriting from Base Job: | |
| # | |
| # # app/jobs/some_task_job.rb | |
| # class SomeTask < BaseJob |
| # Optional but convenient: use C-b v to paste the tmux buffer. | |
| bind v paste-buffer | |
| # Do not exit from copy-mode when selecting text. | |
| # @see https://github.com/tmux/tmux/issues/337 | |
| # Note: the setting might be renamed MouseDragEndX. | |
| # Depending on whether you activated tmux or vi keybindings (I'm using vi mode): | |
| #bind -temaics-copy MouseDragEnd1Pane copy-selection -x | |
| bind -tvi-copy MouseDragEnd1Pane copy-selection -x |
| class Model | |
| # Let's say Elasticsearch needs a JSON representation of the model in order | |
| # to index it. We delegate to a specialized class to generate that JSON: | |
| def as_indexed_json | |
| ModelSerializer.new(self).as_json | |
| end | |
| end |
