I'm Jafar Rezaei (SayJeyHi) - currently I Frontend team lead at Hoory AI assistant team. I love javascript/typescript, and I also like teaching to other people. That's why I wrote two books to make learning javascript and reactjs easier, it is open source and available in Mariotek repository [ github ]. I also translate a book about reactjs interview questions which could help people to have easier interviews [ github ].
