When reconciling transaction logs, partitioning a continuous stream of records into fixed-size batches is necessary. This approach, much like chunking slices in Go for concurrent ledger processing, satisfies downstream throughput limits and maintains strict auditability.
The TypeScript Batch utility relies exclusively on the native standard library. Eliminating external dependencies prevents the introduction of non-deterministic behavior that could compromise the exact-once semantics required for financial calculations.

Execute the accompanying test suite adjacent to the core implementation. Doing so provides concrete validation of the partitioning logic and ensures that edge cases, such as empty inputs or uneven remainders, are handled with the exactness expected in a regulated environment.
