01Understand

The mental model

A language describes intent. A toolchain transforms that intent into a representation the runtime can process; compiled and interpreted describe stages, not two airtight language families.

Precise anchors

Source code: Text written and maintained by people.
Compilation: Transformation of a program into another representation.
Interpretation: Execution controlled by an environment that reads a program representation.
Runtime: Environment and services available during execution.

02Produce

Short reformulationExplain why “JavaScript is interpreted” does not describe the entire execution chain.

Use your own words and connect ideas through cause or consequence.

Concrete artifactTrace two concrete chains: a JavaScript file in a browser and a C program. Use one line per stage and name the tool or environment.

Observable rubric

Both chains start from a source file.
Each arrow names a transformation or environment.
The final stage is actually executable.

Observable decision traceWrite Facts, Hypothesis, Action and Result. Describe observable evidence without narrating private chain of thought.

A strong example will appear after your first attempt.
