### What it does

Disallow unnecessary calls to `.bind()`.

### Why is this bad?

This rule is aimed at avoiding the unnecessary use of `bind()`
and as such will warn whenever an immediately-invoked function expression (IIFE) is using `bind()`
and doesn’t have an appropriate `this` value.
This rule won’t flag usage of `bind()` that includes function argument binding.

### Examples

Examples of **incorrect** code for this rule:

```js
const x = function () {
  foo();
}.bind(bar);

const z = (() => {
  this.foo();
}).bind(this);
```

Examples of **correct** code for this rule:

```js
const x = function () {
  this.foo();
}.bind(bar);
const y = function (a) {
  return a + 1;
}.bind(foo, bar);
```
