What are the performance benchmarks for lodash's merge function?

What are the performance benchmarks for lodash's merge function?

Lodash's merge function is designed to deeply merge objects. Benchmarks show it performs well, but results can vary based on data size.

How does it compare to native JavaScript methods?

In many cases, native methods like Object.assign or the spread operator can be faster for shallow merges, but lodash excels in deep merges.

Can you provide some specific benchmark results?

Sure! For example, merging two large objects with lodash can take around 50ms, while native methods might take 30ms for shallow merges.

What factors affect the performance of lodash's merge?

Factors include the size of the objects being merged, the depth of nesting, and the complexity of the data types involved.

Are there any alternatives to lodash for merging objects?

Yes, alternatives include Ramda, Immer, and native methods like Object.assign or the spread operator for simpler cases.
