   If it were in the Rust language, there is a type called string slice (&str) which can avoid copying each substring into other memory space. After splitting, it can just returns an array of string slices ([&str]), that should be pretty fast.

   However, in Node.js, the use of napi_create_string_* functions causes cloning. I don't see any other functions in N-API that can create JS strings. Maybe it is not possible to prevent it.
