Coding-Easy-Chunk-Array

The model receives the prompt (and optional system message). The run uses scorer javascript_function_tests with the JSON configuration below. Pass/fail and partial credit are determined entirely by that scorer against the model output; no human grading.

Return JSON only with a string field named code. The code must be dependency-free JavaScript, define the requested function in the top level or module.exports, and include no markdown, imports, require, timers, network, filesystem, eval, or placeholders.

Implement function chunkArray(arr, size). Split the array into consecutive chunks of length size. The last chunk may be smaller if the array length is not evenly divisible. Return an array of chunks.

Your JSON must look like {"code":"function chunkArray(...) { ... }"}.
