Merge 295fe153ad into 24b1b02d52

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below the description to indicate that this method of accessing an indefinite number of function arguments has been superseded by the use of the spread operator via rest parameters for ES6+ compatibility.

+# Prevent erb_lint From Removing Opening Tags
+
+The [`erb_lint` gem](https://github.com/Shopify/erb_lint) is a tool from
+shopify for linting and auto-formatting ERB files. When I first set it up in a
+Rails codebase with the base `.erb-lint.yml` recommended in the README, I ran
+into a pernicious issue. The linter wanted to remove opening tags (i.e. `<%`
+and `<%=`) from my ERB files.
+
+So, for a file that looked like this:
+
+```erb
+<div>
+  <%= form_with(url: login_path, scope: :session) do |f| %>
+    <div>
+      <%= f.label :email %>
+      <%= f.email_field :email %>
+    </div>
+</div>
+```
+
+It would get formatted to this:
+
+```erb
+<div>
+form_with(url: login_path, scope: :session) do |f| %>
+    <div>
+f.label :email %>
+f.email_field :email %>
+    </div>
+</div>
+```
+
+Yikes!
+
+I had to disable a couple rules (under `rubocop_config:`) in the `.erb-lint.yml` file to get it to stop
+doing this.
+
+```yaml
+Layout/InitialIndentation:
+  Enabled: false
+Layout/TrailingEmptyLines:
+  Enabled: false
+```
