Use Expressions when possible\* as they are faster than scripts, but brandon1 is right, using `runScript` is faster than using a script transform. \*I have yet to try it, but many Expression limitations can be addressed with pturmel's Integration Toolkit module: > [@Automation Professionals' Integration Toolkit Module](https://forum.inductiveautomation.com/t/automation-professionals-integration-toolkit-module/74934): > > Automation Professionals is pleased to announce the immediately availability of a major upgrade to its free Simulation Aids Integration Toolkit module. The new feature justifying the "major upgrade" language is the implementation of eleven thirty-one new expression functions which use iteration to accomplish complex transforms of datasets and lists, to or from other datasets and lists, applying filtering, ordering, and computed new columns along the way.
