@Abhijit25Mishra please do these changes which I have suggested you and one more thing please remove the extra files which have been committed
package-lock.json

Your content looks great. Thanks for your hard work.

[Abhijit25Mishra]

OK, I have committed all of your changes, sorry for the typos and markdown error. There were no guidelines for that, so I looked at other files and took a guess whether they were H₂ or H₃.
I have also removed the package-lock.json, NPM added or deleted some files due to some updates.
Thank you for all the help.

[Utkarsh1504]

also please remove these.

@Abhijit25Mishra I think If I will merge your PR package-lock.json file will be removed from the main project so please add this again. If there will be any vulnerability I will fix them.
So please man commit that then I'll merge your request as I was not aware of it.
