Question re: difficulty

Back in 2011 or so, I was a Dreamweaver dev using a set of extensions by a company in Eastern Europe that produced dynamic PHP web sites. I don’t remember the name of the extensions but know Adobe bought out the European company and eventually killed off the product. Before that I used Ultradev and was creating ASP stuff.

Anyway, I’ve since retired but have been getting the itch to create some stuff again and ran across Wappler. I’m just curious if the concepts are still pretty similar to what they were. How much trouble am I going to have to get back up to speed? (Yeah, I know there’s been some changes - the whole NodeJS stuff is new to me, etc.) Still, will it take much time to get back in the swing of things?

Thanks.
