+### Classic Helpers
+
+Sometimes, you may encounter helpers defined using the `helper` function:
+
 ```js {data-filename="app/helpers/substring.js"}
 import { helper } from '@ember/component/helper';
 
-function substring([string], { start, end }) {
+function substring(positional, { start, end }) {
+  const string = positional[0];
   return string.substring(start || 0, end);
 }
 
 export default helper(substring);
 ```
 
+<div class="cta">
+  <div class="cta-note">
+    <div class="cta-note-body">
+      <div class="cta-note-heading">Zoey says...</div>
+      <div class="cta-note-message">
+        Before Ember 4.5, this was the only way to define helpers.
+      </div>
+    </div>
+    <img src="/images/mascots/zoey.png" role="presentation" alt="">
+  </div>
+</div>
+
+By wrapping the function using the `helper()` function, Ember will extract the
+arguments passed from the template. It'll then call your function with an array
+(positional arguments passed in the template) and an object (named arguments
+passed in the template).
+
+This style mostly exists for backwards compatibility reasons, but the other
+advantage is that it makes it easier to untangle the positional and named
+arguments (e.g. when your helper accept an arbitrary number of positional
+arguments and optionally some named arguments). Note that, however, it also
+makes it more difficult to reuse the logic of the helper function from regular
+JavaScript code outside of templates. On the other hand, if you define your
+helpers as plain JavaScript function, as we have been doing until now, you are
+able to import and call them from any JavaScript files in your app.

 ### Class Helpers
