How to write from .tpl to twig?

Question

Template Engines

Good afternoon. The tpl file has this script

<script>
                catFilterList = $.grep('<?php echo  preg_replace('/\s/', '',$params['filter_categslist']); ?>'.split(';'),function(n){ return n != "" });
              </script>

I rewrite it in a twig file like this

<script>
                catFilterList = $.grep('{{ preg_replace('/\s/', '', params['filter_categslist'] ) }}'.split(';'),function(n){ return n != "" });
              </script>

gives a syntax error.
Plz tell me what is the problem?
