Translate requirements into platform code
Developer preparation should connect syntax to platform behaviour. Begin each exercise with a business requirement, decide what can remain declarative, and use code only where it adds the necessary control.

Explain “Translate requirements into platform code” in your own words. Can you give a practical example and describe a mistake to avoid?

Developer preparation should connect syntax to platform behaviour. Begin each exercise with a business requirement, decide what can remain declarative, and use code only where it adds the necessary control.
Explain the transaction boundary, records involved, user permissions, and expected result before writing Apex or a Lightning component.

Build bulk-safe Apex habits
Practise collections, selective queries, bulk DML, trigger context variables, and separation of trigger logic into testable classes. Review how the same code behaves for one record and for hundreds of records in one transaction.
- Avoid SOQL and DML inside loops.
- Use sets and maps to organise related records.
- Check trigger events and changed values explicitly.
- Design error handling that helps users correct input.

Test outcomes and boundaries
A useful Apex test verifies observable behaviour, not only code coverage. Create focused data, run the operation, and assert the record changes, returned values, errors, or asynchronous result.
Include positive, negative, bulk, and permission-sensitive cases where relevant. Keep tests isolated from organisation data.

Connect user interface and server logic
Review Lightning Web Component composition, reactive data, events, Lightning Data Service, Apex calls, caching, and error states. Choose the simplest data-access approach that respects security and delivers the required experience.

Revise through small working projects
Build several small features rather than one oversized project. Examples include a validated record service, a bulk trigger, an asynchronous update, and a component that reads and updates data securely. Follow each build with timed scenario practice.
