# no-useless-call

> Disallow `.call()` and `.apply()` where a normal call does the same

`.call()` and `.apply()` exist to choose what `this` is. If `this` ends up the same as in a normal call, they only make the call harder to read.

A call is reported when a plain function gets `null` or `undefined` as `this`, or when a method gets the object it's read from. `.apply()` is only reported when its second argument is an array literal.

## Examples

Reported:

{/* bad {"count": 3} */}
```js
format.call(undefined, value, locale);
format.apply(null, [value, locale]);
logger.write.call(logger, message);
```

Not reported:

{/* good */}
```js
format(value, locale);
logger.write(message);

// `this` is a different object
logger.write.call(otherLogger, message);

// the arguments are not known here
format.apply(undefined, args);
```
