Questions

Any questions for reviewers of this pull request?

yes

• In main.js, I am not validating whether the value parameter matches the specified data type (dtype) because I haven't found any method that validates data based on the dtype input. Additionally, the set method does not validate the input value. If validation is required, please let me know.
