Avoiding coding using purpose-built steps
You saw through the exercises how powerful the JavaScript and Java Class steps are to help you in your transformations. In older versions of PDI, coding JavaScript was the only means you had for specific tasks. In the latest releases of PDI, actual steps appeared that eliminate the need to code in many cases.
