    Thank you very much sir. I learned a lot. My perspective towards the design pattern is changed.

    Design patterns only exist because OOP was an insufficient tool for communication and expression.

    what was it that he did at 8:01 ? Making a tick on the todo list in the editor. How to do that ?

      That is exactly what I'm trying to figure out right this second. Did you ever find an answer?

      On VSCode it's ToDo+, default toggle is alt+d for done. Todo+ has plugins for most editors.

    I don't hate design patterns exactly but I hate the way those architects boast about the design patterns in every meeting, as they know nothing except those & make the life of actual developers a hell...
