Readable code. Precise contracts.

Learn each language concept with complete examples, supported syntax and the boundaries that matter in a real application.

Keep data in its useful type, and convert explicitly at the boundary between a user interface and your logic.

Define small callable contracts and be explicit about mutation, defaults and return values.

Express decisions directly and stop loops at a clearly defined boundary.

Choose a container by how you need to find, order and change its values.

Separate stateless helpers from instance state, and keep object ownership visible.

Separate compiler diagnostics from runtime failures and preserve the operation’s cleanup path.

Keep the interface responsive while respecting McBasic™’s deliberately bounded asynchronous syntax.

Read structured data by shape, and distinguish transport results from the response body.

Exact API contracts#

Compiler-owned signatures, parameter types and supported overloads.

SQLite, HTTP, JSON, application paths and reporting.
