Unit 1 / 4
Identity and authority
Authorize the particular object and operation, using trusted identity.
Before you start: Read JavaScript functions and object updates. For the rendering and data units, know DOM text versus HTML and SQL SELECT / WHERE. The first theory lesson checks identity and ownership before code execution.
The course, in order
Open a unit in the map to inspect its activities. Reading, guided completion, independent work and review remain distinct evidence.
- Identity and authority
Authorize the particular object and operation, using trusted identity.
Open this unit - Writable data and rendering
Constrain writes and keep stored text separate from executable markup.
Open this unit - Queries and business invariants
Separate SQL structure from values, scope aggregates, and derive prices from trusted data.
Open this unit - Replay, failures and transfer
Preserve idempotency and safe errors, then repair a revision workflow independently.
