A set of custom plugins to enforce high performance JS

## Example

```js
{
    "rules": {
        "perf-standard/no-instanceof-guard": 2,
        "perf-standard/no-self-in-constructor": 2,
        "perf-standard/check-function-inline": 1
    }
}
```

Currently the plugins we have are:

### `no-instanceof-gaurd`

This disables the common anti-pattern of:

```js
function Foo() {
  if (!(this instanceof Foo)) return new Foo()
}
```

### `no-self-in-constructor`

This disables the ability to use `var self = this` in
the body of a constructor function.

For performance reasons we should use `this.foo = bar;` in
constructors.

Using `var self = this` in methods is fine.

### `check-function-inline`

This lint rule checks to see if a function is between 600
and 660 characters and then warns that the function will not
be inlined in V8.

## Installation

`npm install eslint-plugin-perf-standard`

## Tests

`npm test`
