Yeah, this isn't really an issue; it's just a templating language. You can get an extension for your IDE to make it syntax highlight correctly. That's like saying a .js file is just a string. Um, yes I guess sure? All code is just a string. HTML is also just a string. Vue's HTML templating syntax is also just a string, but it's also code. It's code that's mainly HTML, with certain spots that allow full JavaScript. And just like normal code, you can have compile time errors, syntax errors, runtime errors, etc.

Also as a side note: I'd say the best thing about Vue isn't it's templating system, but the fact that it's truly reactive. In react, only rendering is truly reactive. If you have reactive variables that depend on each other, then you have to manually mark those dependencies. Vue can deduce that dependency graph automatically, which makes coding much easier. It's like a giant spreadsheet.

This is exactly the point of vue. On the surface, it looks a lot like a cleaner angularjs, but it's very different. There's no need for a digest cycle to re-evaluate watch expressions on each iteration, because it uses getters and setters to detect changes (though it still supports watchers too). Vue is also very different from React, which (when I last used it) required components to implement shouldComponentUpdate. Vue does this at the cost of breaking compatibility with older browsers (which were not old at all when React and Angular 1.0 came out); I think the tradeoff is worth it.
