[Problem] Check if a value is present in a child node - server side js

I love drafting the issues I get stuck when I work on something. I know I might be the last one in the wagon But better late than never to learn a bit of server side js for sightly. Those who stumble upon something same should have a helping hand around and hope this might help a few . I tried to draft it in one place and since I dont have a blog of my own , please feel free to check my Linkedin and you can find the article here https://www.linkedin.com/pulse/aem-check-value-present-child-node-server-side-js-veena-vikraman/

Happy Coding
