I recently implemented a strategy pattern, for rendering cards on a page. The rendering logic was a little bit different for each card. Then I used a factory to instantiate the different strategies and pass the correct strategy too the view, worked really nicely

Thanks, man :) There's going to be room for refactoring for sure, but I don't know if this particular pattern applies unless she's writing JavaScript.

@@jeckart3d Yeah I remember there was an option to write actual JS or use the visualizer tool to make it easier. I wonder if there's a full JS engine behind that thing. Probably.🤷🏻♂️

I 'm still confusing, why people use constructor functions if exists factory. Factory functions more flexible: it's not reqired 'this' and 'new' keywords, haven't privacy issues and don't have a problems with losing context with 'this' when we have a nested functions. Can you explain in which cases we should use 'constructor' ?
@ColorCodeio 3 жыл бұрын
Yep, explaining that in episode 5.
