Hello @bossenti I would like to take up this issue. As I am completely new to open source I would be thankful to you if you can tell me what to do exactly.

Hi @Sayan108,

great to hear! As a first step, I would recommend that you check out the repository and have a look at the sample unit tests that are linked in the issue. You can try running them first in your IDE, and then start with the implementation for the unit test for the JSEvalProcessor.
