Get the currently installed [`npm` CLI](https://github.com/npm/npm) version

```javascript
const npmCliVersion = require('npm-cli-version');

(async () => {
  await npmCliVersion(); //=> '5.5.1'
})();
```

Unlike the [prior](https://github.com/ngryman/npm-v) [arts](https://github.com/vvo/npm-version), it doesn't [execute](https://nodejs.org/api/child_process.html#child_process_child_process_exec_command_options_callback) `npm --version` in a child process.

## Installation

```
npm install npm-cli-version
```

## API
