Pull Request

We have long been wanting to adopt more modern conventions including ES2015 additions, and can start doing so as we have dropped support for older versions of node.

I am starting small with Option to discuss any questions this raises.

Problem

Using prototype for implementing Option class is unfamiliar to new programmers, and noisy.

Solution

Refactor code using class.

The code compare is very noisy with whitespace included, but looks tidy with whitespace ignored.

I had to search to find the whitespace controls: you can ignore whitespace from the cog in the "Files changed" view, or add ?w=1 to the URL.

5134077 
***
☝️ **Important announcement:** Greenkeeper will be saying goodbye 👋 and passing the torch to Snyk on June 3rd, 2020! [Find out how to migrate to Snyk and more at greenkeeper.io](https://greenkeeper.io)
***
## The dependency [commander](https://github.com/tj/commander.js) was updated from `4.1.1` to `5.0.0`.
This version is **not covered** by your **current version range**.

If you don’t accept this pull request, your project will work just like it did before. However, you might be missing out on a bunch of new features, fixes and/or performance improvements from the dependency update.

<li>throw for author error, not just display message</li>
<li>preflight for variadic error</li>
<li>add tips to missing subcommand executable</li>
</ul>
</li>
<li>TypeScript fluent return types changed to be more subclass friendly, return <code>this</code> rather than <code>Command</code> ([<a class="issue-link js-issue-link" data-error-text="Failed to load title" data-id="561948792" data-permission-text="Title is private" data-url="tj/commander.js#1180" data-hovercard-type="pull_request" data-hovercard-url="/tj/commander.js/pull/1180/hovercard" href="https://urls.greenkeeper.io/tj/commander.js/pull/1180">#1180</a>])</li>
<li><code>.parseAsync</code> returns <code>Promise&lt;this&gt;</code> to be consistent with <code>.parse()</code> ([<a class="issue-link js-issue-link" data-error-text="Failed to load title" data-id="561948792" data-permission-text="Title is private" data-url="tj/commander.js#1180" data-hovercard-type="pull_request" data-hovercard-url="/tj/commander.js/pull/1180/hovercard" href="https://urls.greenkeeper.io/tj/commander.js/pull/1180">#1180</a>])</li>
<li>update dependencies</li>
</ul>
<h3>Removed</h3>
<ul>
<li>removed EventEmitter from TypeScript definition for Command, eliminating implicit peer dependency on <code>@types/node</code> ([<a class="issue-link js-issue-link" data-error-text="Failed to load title" data-id="548333754" data-permission-text="Title is private" data-url="tj/commander.js#1146" data-hovercard-type="pull_request" data-hovercard-url="/tj/commander.js/pull/1146/hovercard" href="https://urls.greenkeeper.io/tj/commander.js/pull/1146">#1146</a>])</li>
<li>removed private function <code>normalize</code> (the functionality has been integrated into <code>parseOptions</code>) ([<a class="issue-link js-issue-link" data-error-text="Failed to load title" data-id="547256656" data-permission-text="Title is private" data-url="tj/commander.js#1145" data-hovercard-type="pull_request" data-hovercard-url="/tj/commander.js/pull/1145/hovercard" href="https://urls.greenkeeper.io/tj/commander.js/pull/1145">#1145</a>])</li>
<li><code>parseExpectedArgs</code> is now private ([<a class="issue-link js-issue-link" data-error-text="Failed to load title" data-id="548552171" data-permission-text="Title is private" data-url="tj/commander.js#1149" data-hovercard-type="pull_request" data-hovercard-url="/tj/commander.js/pull/1149/hovercard" href="https://urls.greenkeeper.io/tj/commander.js/pull/1149">#1149</a>])</li>
</ul>
<h3>Migration Tips</h3>
<p>If you use <code>.on('command:*')</code> or more complicated tests to detect an unrecognised subcommand, you may be able to delete the code and rely on the default behaviour.</p>
<p>If you use <code>program.args</code> or more complicated tests to detect a missing subcommand, you may be able to delete the code and rely on the default behaviour.</p>
<p>If you use <code>.command('*')</code> to add a default command, you may be be able to switch to <code>isDefault:true</code> with a named command.</p>

<h3>Migration Tips</h3>
<p>If you use <code>.on('command:*')</code> or more complicated tests to detect an unrecognised subcommand, you may be able to delete the code and rely on the default behaviour.</p>
<p>If you use <code>program.args</code> or more complicated tests to detect a missing subcommand, you may be able to delete the code and rely on the default behaviour.</p>
<p>If you use <code>.command('*')</code> to add a default command, you may be be able to switch to <code>isDefault:true</code> with a named command.</p>

</ul>
<h3>Migration Tips</h3>
<p>If you use <code>.on('command:*')</code> or more complicated tests to detect an unrecognised subcommand, you may be able to delete the code and rely on the default behaviour.</p>
<p>If you use <code>program.args</code> or more complicated tests to detect a missing subcommand, you may be able to delete the code and rely on the default behaviour.</p>
<p>If you use <code>.command('*')</code> to add a default command, you may be be able to switch to <code>isDefault:true</code> with a named command.</p>

## The dependency [commander](https://github.com/tj/commander.js) was updated from `4.1.1` to `5.0.0`.
This version is **not covered** by your **current version range**.

If you don’t accept this pull request, your project will work just like it did before. However, you might be missing out on a bunch of new features, fixes and/or performance improvements from the dependency update.

<h3>Migration Tips</h3>
<p>If you use <code>.on('command:*')</code> or more complicated tests to detect an unrecognised subcommand, you may be able to delete the code and rely on the default behaviour.</p>
<p>If you use <code>program.args</code> or more complicated tests to detect a missing subcommand, you may be able to delete the code and rely on the default behaviour.</p>
<p>If you use <code>.command('*')</code> to add a default command, you may be be able to switch to <code>isDefault:true</code> with a named command.</p>

</ul>
<h3>Migration Tips</h3>
<p>If you use <code>.on('command:*')</code> or more complicated tests to detect an unrecognised subcommand, you may be able to delete the code and rely on the default behaviour.</p>
<p>If you use <code>program.args</code> or more complicated tests to detect a missing subcommand, you may be able to delete the code and rely on the default behaviour.</p>
<p>If you use <code>.command('*')</code> to add a default command, you may be be able to switch to <code>isDefault:true</code> with a named command.</p>
