Hi, I am new here obviously. I am about to take the zce exam next week and am having trouble understanding the design patterns. fortunately I bumped to this portal through googling and I am really thankful such bright devs exists in here to give very clear tutorials to noobs like me.

Welcome to the community, Sasori.

Good luck with your exam!
