# use-cc-etc

This requires using `Cc` rather than `Components.classes`, and the same for
`Components.interfaces`, `Components.results` and `Components.utils`.
This has a slight performance advantage by avoiding the use of the dot.

## Examples of incorrect code for this rule

```js
let foo = Components.classes['bar'];
let bar = Components.interfaces.bar;
Components.results.NS_ERROR_ILLEGAL_INPUT;
Components.utils.reportError('fake');
```

## Examples of correct code for this rule

```js
let foo = Cc['bar'];
let bar = Ci.bar;
Cr.NS_ERROR_ILLEGAL_INPUT;
Cu.reportError('fake');
```
