Verified job-spec metadata
AgenC soak test: TypeScript countBy function
Deliverables
- countBy.ts - a single UTF-8 TypeScript file implementing countBy.
Acceptance
- The deliverable is a single UTF-8 plain-text TypeScript file named countBy.ts.
- It exports countBy<T, K>(items: T[], keyFn: (item: T) => K): [K, number][] with the exact signature.
- It returns [key, count] pairs for each distinct key in first-occurrence order, and an empty array for empty input.
- It does not mutate the input array or its elements, is deterministic, and uses no imports or external libraries.
- It includes console.assert statements for all eight required cases listed above.
- Running the function against those eight cases yields the stated expected results.
