> An eslint plugin to enforce method or function name conforms to conventions.

## Installation

You'll first need to install [ESLint](http://eslint.org):

```sh
npm i eslint --save-dev
```

Next, install `eslint-plugin-function-name`:

```sh
npm install eslint-plugin-function-name --save-dev
```

## Usage

Add `function-name` to the plugins section of your `.eslintrc` configuration file. You can omit the `eslint-plugin-` prefix:

```json
{
"plugins": [
"function-name"
],
"rules": {
"function-name/starts-with-verb": "error"
}
}
```

## Supported Rules

### function-name/starts-with-verb

Function is always do something, so it should start with a verb and to avoid confusion with variables.

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

```js
function cat(fish) {}
function dog(distance) {}

```js
function feedCat(fish) {}
function walkDog(distance) {}

interface IOptions {
whitelist: string[];
blacklist: string[];
}

{
"rules": {
"function-name/starts-with-verb": ["error", {
"whitelist": ["success"],
"blacklist": ["init"]
}]
}
}
