 ### Naming conventions
 
-* JS names are camelCase `fooBar`
-  * initial lowercase for variables and functions `fooBar`
-  * initial uppercase for classes and namespaces `Foo.Bar`
-  * all-caps for constants
-* CSS classes are kebob-case. `foo-bar`
+* JavaScript variable and function names should be `camelCase`.
+
+```js
+// bad
+let foobar;
+let Foobar;
+let FooBar;
+
+// good
+let fooBar;
+```
+
+* JavaScript constants should be `ALLCAPS`.
+
+```js
+// bad
+const foo = 'foo';
+const fooBar = 'fooBar';
+
+// good
+const FOO = 'foo';
+const FOOBAR = 'fooBar';
+```
+
+* JavaScript classes and namespaces should be `PascalCase`.
+
+```js
+// bad
+class foo {}
+class FOO {}
+App.foo.bar();
+
+// good
+class Foo {}
+App.Foo.bar();
+```
+
+* CSS classes are `kebob-case`.
+
+```css
+/* bad */
+.fooBar {}
+.FOO-BAR {}
+
+/* good */
+.foo-bar {}
+```
 
 New code should generally get organized into the `App` namespace. See `js/002-config/fc-init-js.js` for a rough outline.
