Why do they say their template system is simpler than JSX? You have to learn a whole lot of new stuff and syntax is barely readable. Whereas JSX is clear and you can use already familiar JavaScript.
I wonder if we will ever have a satisfactory solution to the template problem of conditional rendering. All I've seen so far solved one problem only to bring another. To some degree, this is really a dogmatic problem, which is why it'd be nice if we could solve this and move on with more important things.
It's the same old balance problem: more flexibility and less constraints opens up potentially dangerous misuse.
We see it with languages too I.e C memory management vs garbage collection.
We also see it socially too. There are particular problems with both 0% regulation and 100% regulation, with the ideal that nobody can agree on lying somewhere in between. In fact, some situations call for more or less, compounding the confusion.
Perhaps the solution is a template system that can fit current needs, in that a programmer can choose to remove a restriction but the removal of the restriction gives the seconds required to think if removing a restriction is necessary.
That then means we can collaborate as an industry. We may find that there exists one or a handful of "ideal general restrictions". We may also find that actually for certain types of problem would do well with a handful of specific restrictions that work well there.
I just don't think there is a one size template solution and our attempts at a fixed ideal haven't seemed to work. After all, if we had the true ideal, we wouldn't keep making new ones.
JSX doesn't run in browsers.
