Autogenerated LLM Summary

, generated one year ago):
It seems like we're ready to dive into the benchmarking data! Based on the provided data, I'll answer your question: Which JavaScript library is faster for merging objects: Immutable.js or Ramda? According to the latest benchmark result, Immutable.js is currently faster with an average of 103819 executions per second. This indicates that Immutable.js can perform object merges more efficiently than Ramda. Here's a summary of the results: | Test Name | Average Executions/Second | | --- | --- | | Immutable | 103819 | | Ramda.mergeDeepRight | 1828709 | | Lodash.merge | 17742 | Keep in mind that benchmarking results can vary depending on the specific use case, object sizes, and other factors. However, based on this data, Immutable.js appears to be the faster choice for merging objects. Would you like me to explain anything else about these results or provide further insights?
