 This will return a promise that fulfills with the requested record:
 
 ```javascript
-let blogPost = this.get('store').findRecord('blog-post', 1); // => GET /blog-posts/1
+// GET /blog-posts/1
+this.get('store').findRecord('blog-post', 1)
+  .then(function(blogPost) {
+    // Do something with `blogPost`
+  });
 ```
 
 Use [`store.peekRecord()`](https://www.emberjs.com/api/ember-data/release/classes/DS.Store/methods/findRecord?anchor=peekRecord) to retrieve a record by its type and ID, without making a network request.
 This will return the record only if it is already present in the store:
 
 ```javascript
-let blogPost = this.get('store').peekRecord('blog-post', 1); // => no network request
+// no network request
+let blogPost = this.get('store').peekRecord('blog-post', 1);
 ```
 
 ### Retrieving Multiple Records
 
 Use [`store.findAll()`](https://www.emberjs.com/api/ember-data/release/classes/DS.Store/methods/findAll?anchor=findAll) to retrieve all of the records for a given type:
 
 ```javascript
-let blogPosts = this.get('store').findAll('blog-post'); // => GET /blog-posts
+// GET /blog-posts
+this.get('store').findAll('blog-post')
+  .then(function(blogPosts) {
+    // Do something with `blogPosts`
+  });
 ```
 
 Use [`store.peekAll()`](http://emberjs.com/api/data/classes/DS.Store.html#method_peekAll) to retrieve all of the records for a given type that are already loaded into the store, without making a network request:
 
 ```javascript
-let blogPosts = this.get('store').peekAll('blog-post'); // => no network request
+// no network request
+let blogPosts = this.get('store').peekAll('blog-post');
 ```
 
 `store.findAll()` returns a `DS.PromiseArray` that fulfills to a `DS.RecordArray` and `store.peekAll` directly returns a `DS.RecordArray`.
