Unit 3 · Module 1

What Even Is a Script?

Scripts vs apps, the host idea, and the anatomy that’s the same everywhere

Where this module sits

Unit 1 covered JavaScript. Unit 2 covered databases. Neither one explained what a script actually is, even though Google Apps Script, Airtable automations, and webhook handlers are probably already part of your day.

The three pages

  1. Scripts In Relation To Apps. Where scripts sit, what apps host them, and the three jobs scripts almost always do.
  2. The Host Idea. Why one line of script code is part-yours, part-Google’s, part-JavaScript — and how to tell which is which.
  3. Anatomy Of A Script. The four parts every script has: entry point, host objects, the work, the trigger.

This module stays one level above any specific host. Module 2 picks up Google Apps Script. Module 3 picks up Airtable.
