You think this is a joke but Meta/Facebook has something similar for interop between XHP (https://github.com/hhvm/xhp-lib) and React.

What Hacker News says
12 sourcesIntelliJ will detect cases like that, yes. But it is difficult and slow to get IntelliJ to inspect your whole project like `tsc` does. With PHPStan or such tools you can do that more easily, but they still have interop problems due to non-standard annotation syntax. Having native support for such type expressions would be much better.
ES6 has Map and Array, which are perfectly sufficient and distinguishable from each other. PHP core only has array() which tries to do everything. You can use array() to build a collection or an associative array and you cannot force it to only behave as one of those. Even Zend's PHP certification contains questions about what happens if you try to push a value into an array that uses associative keys. This is a joke.
I prefer React over Angular as well, but interactivity was not on my list of goals. I want

a template syntax that combines valid markup, escaping by default, and TSX-style typechecking. Basically, I want XHP [0]. There is no other template engine for PHP that validates "values passed into this template" against "values used in this template" like TSX can, and no engine that ensures you're generating valid XML/HTML markup. I certainly agree that this is far less important than powerful types, but hey, one can dream :)

Facebook/xhp-lib: Class libraries for XHP
1 points · Open discussionRight, because in any sane templating library you would just have something like
Hello & Welcome {{a}}
but despite being "built for the web", php is not a sane templating language for dealing with html.
Facebook's XHP solves this problem:

"An interesting feature of XHP is the idea of automatic escaping" ... "As you can see, using XHP makes safety the default rather than the exception."

In DHH on the immediacy of PHP (2008)Facebook XHP Expressions for PHP
1 points · Open discussionAFAIK it's not true. First they don't use raw php: https://github.com/facebook/xhp/wiki
Then they use it only for the view layer, it only pull some data from memcache to render HTML.
But all the hard work is C++ / Java / Tornado / etc
In Rambling On [PHP] InternalsIf the JSX inline xml looks vaguely familiar, it's probably because they did the same thing with php (xhp [1]).
One criticism about facebook, google, etc is that the greatest minds are being used to make people click more ads. But they're open sourcing some interesting things so it's not all bad.

2 points · Open discussionFacebook develops their main site in PHP. They even wrote their own PHP compiler[1], and various other pieces of infrastructure (e.g. [2]). I'm not a huge fan of PHP, but compared to other PHP projects I've worked on their infrastructure looks nice and modern.
