That’s the joke
It’s implying js isn’t a programming language because web stuff isn’t real programming
Not even close.
Most software out there is not consumer facing (there is a huge amount of custom stuff inside companies of all sizes) and even in the consumer space most software nowadays resides in … smartphones.
Unless, of course, you count HTML (literally a Markup Language, so data formatting for display not code) as programming, in which case I’ll leave you to enjoy your fantasy world.
You kinda forget that for each front end you see theres at least 4 times more backend to support it.
Also there are ton of non fron facing software.
Anyway its not really a competition. No one will be offended if you are wrong or not.
The back-end functionality is still web functionality. Just because a user doesn’t see all the server stuff doesn’t mean it’s not necessary to support a website. There are billions of websites across the world, and they almost all use some combination of back-end, front-end, database, and server code.
