I have a question, why do we have to put the isUnclock value in useContext and why not put the authenticate function in useContext but put it in layout?

Hello sir Are you looking for a professional RUclips thumbnail designer?

[@bouthouri]

Great work, if only you could make the video shorter.
All the videos are interesting for me but 1 hour is too much.
Less then 30 minutes would be perfect!
Best of luck
