const log = console.log;
const areaSelect = document.querySelector(`[id="area"]`);

// log(`e.target`, e.target);
const select = e.target;
const value = select.value;
const desc = select.selectedOptions[0].text;
log(`option desc`, desc);
});
<div class="select-box clearfix">
<label for="area">Area</label>
<select id="area">
<option value="101">A1</option>
<option value="102">B2</option>
<option value="103">C3</option>
</select>
</div>
