描述

JSPerf suggests that lodash _.map is faster than native Array.map https://jsperf.com/native-map-vs-lodash-map but is there an overhead in loading lodash for a single execution? is it enough to offset the Performance benefits of the module?

研究方向
Investigate the performance trade off between using lodash's .map vs native Array.map in AWS Lambda functions. Start by reading the linked jsperf results. Then set up a simple Lambda function that benchmarks both approaches with realistic data sizes, measuring execution time and cold start overhead. Consider the size of lodash bundle and its impact on Lambda cold starts. Document findings and provide a recommendation. No existing PRs or comments to build upon.
