In this chapter, you learned to code JavaScript into PDI. Specifically, you learned:

  • What the JavaScript step is and how to use it
  • How to modify fields and add new fields to your dataset from inside your JavaScript step
  • How to deal with unstructured input data

You also considered the pros and cons of coding JavaScript inside your transformations, as well as alternative ways to do things, avoiding writing code when possible.

As a bonus, you learned the concept of named parameters.

If you feel confident with all you've learned until now, you are certainly ready to move on to the next chapter, where you will learn in a simple fashion how to solve some sophisticated problems such as normalizing data from pivot tables.
