Naming convention for const object keys in ES6 : <p>Is there a recommended naming convention for key names within a const object in es6? I haven't been able to find a resource which states if they should be uppercase or lowercase.</p>

<pre><code>const COLOR_CODES = {
  BLUE: 1,
  RED: 1
};
</code></pre>

<p>vs</p>

<pre><code>const COLOR_CODES = {
  blue: 1,
  red: 1
};
</code></pre>

<p><a href="https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Statements/const" rel="noreferrer">The examples</a> from this MDN article show both styles, so maybe both are acceptable.</p>
