Watch a before-insert trigger written live: one trigger per object, logic in a handler class, bulk-safe from the first line.

## The pattern before the syntax

One trigger per object, no logic in the trigger body, a handler class with one method per event. Learn the pattern first and you will never untangle spaghetti later.

## Before vs after

Before triggers change the records in flight for free; after triggers see final field values and Ids. Choosing wrong costs you a query or an error.

## Practice in your org

- Open your Developer Edition org and follow along step by step
- Change one thing at a time and note what happens
- When something breaks, read the error before searching for it
