Hey Guys , Here I am with a useful thing for all of u to do during this lockdown period. I think most of u would have gone to ur work places but for the people sitting home idol this will be useful. U can learn new courses in programming languages, coding and make projects create webpages. For learning I would prefer u to do in online.
