title: How to convert a currency string to a double with Javascript?
body: <p>I have a text box that will have a <em>currency</em> string in it that I then need to convert that string to a double to perform some operations on it. </p>
  
  <p><code>"$1,100.00"</code> → <code>1100.00</code></p>
  
  <p>This needs to occur all client side. I have no choice but to leave the <em>currency</em> string as a <em>currency</em> string as input but need to cast/convert it to a double to allow some mathematical operations. </p>
