Object.entries() alternative for Internet Explorer and ReactJS : <p>Well, I've been building a web application for a couple weeks now, and everything good. I got to the part that I had to test in Internet Explorer, and of all of the things that came up (all fixed except for one), Object.entries() is not supported.</p>

<p>I've been doing some research and try to come up with a simple alternative, but no luck at all.</p>

<p>To be more specific, I'm bringing an object from an API, to fill options for <code>&lt;select&gt;&lt;/select&gt;</code> fields I have to filter some information, just like this:</p>

<pre><code>Object.entries(this.state.filterInfo.sectorId).map(this.eachOption)

// Function
eachOption = ([key, val], i) =&gt; {
    return(
        &lt;option value={val} key={i}&gt;{val}&lt;/option&gt;
    );
}
</code></pre>

<p>So everything works correctly except for Internet Explorer. The thing is that in this particular component I'm rendering over 30 <code>&lt;select&gt;&lt;/select&gt;</code> fields. IF there is a solution that doesn't require me to rebuild everything, it would be amazing.</p>

<p>Is there a simple solution? A way around this?</p>

<p>Thanks in advance.</p>
