HTML Preparation code:

<script>

var s="Since all three methods have roughly equivalent performance, my preference is to use slice. It supports extracting from the end of the string and I feel that returning an empty string when start index > stop follows the principle of least surprise better than substring's swapping of parameters. I avoid substr because of the browser inconsistency.";

Tests:

split
var a=s.split(re); var i,l=a.lenght,w; for(i=0;i<l;i++){ w=a[i]; };
for loop
var i,l=s.lenght,w,lsp=-1; for(i=0;i<l;i++){ if(re.test(s.charAt(i))){ w=s.slice(lsp+1,i); lsp=i } };
