The portfolio will also allow me to integrate what I've learned in HTML/CSS/JAVASCRIPT while documenting the progressive improvements that I'm making.
Personally, I believe the best way to truly master something is by putting what so ever you have learned into action as the case may be for thats coding and the idea of you creating a portfolio website alongside your training shows it all that you are willing and ready to understand it all.
Wish you all the best of luck once more during your training.
