no-compare-against-boolean-literals
===================================
Checks that boolean expressions do not compare against literal values
of ``true`` or ``false``. This is to prevent overly verbose code such as
``if (isEnabled == true)`` when ``if (isEnabled)`` would suffice.
Examples of incorrect code for this rule:
-----------------------------------------
.. code-block:: js
if (foo == true) {}
if (foo != false) {}
if (false == foo) {}
Examples of correct code for this rule:
---------------------------------------
.. code-block:: js
if (!foo) {}
if (!!foo) {}
