I used to use XSLT a lot, though it was a while ago.

You can use Javascript to get the same effect and, indeed, write your transforms in much the same style as XSLT. Javascript has xpath (still). You have a choice of template language but JSX is common and convenient. A function for applying XSLT-style matching rules for an XSLT push style of transform is only a few lines of code.

Do you have a particular example where you think Javascript might be more verbose than XSLT?
