I am still using XSLT. I have been using it for 26 years. I generate XML documents on the backend and turn them into HTML for various reports. XSLT has a lot of features and power that newer templating languages lack.
Are any of these newer templating languages worth me switching?
A great way to convince you you've always been wrong:
Step 1: Gain browser monopoly
Step 2: Generate fake security scare
Step 3: Gaslight everyone that only way to mitigate is to get rid of it completely like Flash.
Step 3a (corollary): There isn't anyone available that can fix the bugs because we spent all resources on UI/UX experimentation
Yes, because XSLT won't work in Chrome and Edge anymore.
