+
+Examples of incorrect code for this rule:
+-----------------------------------------
+
+.. code-block:: js
+
+    if (foo.length == 0) {}
+    if (foo.length > 0) {}
+    if (foo && foo.length == 0) {}
+    function bar() { return foo.length > 0 }
+
+Examples of correct code for this rule:
+---------------------------------------
+
+.. code-block:: js
+
+    if (foo.length && foo.length) {}
+    if (!foo.length) {}
+    var a = foo.length > 0
+    function bar() { return !!foo.length }
