# 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
```js
if (foo == true) {}
if (foo != false) {}
if (false == foo) {}
```
## Examples of correct code for this rule
```js
if (!foo) {}
if (!!foo) {}
```
