Wow it felt so good just getting the run down of this - so many tutorial videos full of fluff but this is right to the point with a real world example! Thank you

I recommend you to make this kind of explanation, something short and concise is desirable by many people. :D

Is this something that we should do to refactor Em’s rainbow?! Also, happy to see a new 1-minute vid!

@ColorCodeio 3 года назад

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 3 года назад

@@ColorCodeio ahhhh, alright. I had thought what she was doing was based on JavaScript but in a “kid-friendly” wrapper.

@ColorCodeio 3 года назад

@@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 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

@mich_thedev Год назад

Nicely explained. Is that how react's jsx. Elements are made?

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 года назад

Yep, explaining that in episode 5.
