JSX is a DSL with the ability to opt out into native JavaScript. So most complex JSX is a composition of JSX with JS driving the logical parts. Does Vue’s templating solution offer the same? (Genuine question, haven’t worked with Vue)
It does. You can do render functions similar to React (and optionally use JSX if you want to). It's not very common though except for library authors (especially if you need to do some clever stuff, regular vue templates can't handle all the corner cases that a raw render function can).
In my eperience, most people do use the templates, and especially in Vue 3, those templates are going to get compiled to extremely optimised render functions. But if you want or need to, you can also write your own render function directly, or indeed use JSX. Vue is remarkably flexible about that.
