Migrate react classes to use the latest hooks

[RAJAGOPALAN-GANGADHARAN]

Either migrating one class at a time(All the essential window wrappers and then the pre installed applications) or Migrating it all at once, Whichever method works fine.

I would like to work on this. Just one doubt: Do I need to change every file with class components to hooks or some specific files only?

Hello @shmiitg , Thank you for your interest in this - we have to migrate every class from classes to hooks but we could do it one by one. Starting from non impacted defaultapps like say minesweeper etc

Sir i have changed the following files:
calender.js
codestudio.js
menubar.js
minesweeper
markdown_editor.js
markdown_reader.js
pdf.js
processmanager.js

I am sending a pr, if you dont find any mistakes you can merge it, I will slowly and gradually change all the files.
