How to write a currency converter in javascript?
<p>How do I search for all parts in a text that contain € or EUR or another currency to convert it to another currency of my choice?</p>

<p>Ie:</p>

<ol>
<li>How do I isolate the number left or right of a € or EUR or another currency sign?</li>
<li>How do I replace that very number with the changed value?</li>
<li>How do I apply this to all numbers of the webpage that have the € or EUR or another currency sign before or after?</li>
</ol>
