UPDATE:

Wohoooo!!! 🎉

All files inside src directory are migrated to typescript. (Except few ones which are already taken up and being worked on), though we are still looking on improvements to types in these files and removing any types from the source. You are welcome to contribute. 😊

__tests__ directory has still some files left that needs migration to typescript, so feel free to pick em up! 🍭
