     /// ### What it does
+    ///
     /// Enforce return statements in callbacks of array methods
     ///
     /// ### Why is this bad?
+    ///
     /// Array has several methods for filtering, mapping, and folding.
     /// If we forget to write return statement in a callback of those, it’s probably a mistake.
     /// If you don’t want to use a return or don’t need the returned results,
     /// consider using .forEach instead.
     ///
     /// ### Example

+    /// Examples of **incorrect** code for this rule:
+    ///
+    /// ```javascript
+    /// let foo = [1, 2, 3, 4];
