I need the Javascript Regular Expression for removing a "-" in first position of a word?

For example, how would I remove the "-" from "-MyTest".  I only need to remove the dash if it is in the first position.

<script type="text/javascript">
  var re = /^-/;
  var sourcestring = "-source string to match with pattern";
  var result = sourcestring.replace(re, "");
  alert("result = " + result);

You don't need a regular expression for this.

if ( sourcestring !=null && sourcestring.length > 1 && sourcestring.startsWith("-") ) {
  sourcestring = sourcestring.substring(1);

StartsWith is a prototype.
sourcestring = (sourcestring.substr(0,1)=='-' ) ? sourcestring.substring(1):sourcestring;
