title: Numbers with commas in Javascript
body: <p>I have a javascript function that accepts a number and performs a mathematical operation on the number.  However, the number I'm passing in could have a comma in it, and from my limited experience with Javascript I am having problems working with that value.  It doesn't seem to treat that as a numeric type.</p>
  
  <p>What's the easiest way to take a parameter with a value of 1,000 and convert it to a numeric 1000?</p>
