You might be looking for web assembly though, which is bytecode running in the browser, just like your 90s Java Applet (but without the security problems).
That’s clearly subjective; most of us feel there has been.
As for performance, not only is JS incredibly fast, but WASM exists if you need more perf than JS offers.
For “protection of intellectual property”, i believe that a license is the most effective means of doing this with any program that executed on someone else’s machine - what do you suggest a language could do about this?
I am posting in this forum because I want the companies which have paid their staff to work on this "language" to explain to me why there has been so little improvement in the Web development programming environment in THREE DECADES.
You don’t have to compile JS to use it, and it works the same as PHP, Python, Ruby, and many other typically interpreted languages.
Again, JS is extremely efficient for many use cases. If that doesn’t include yours, that’s unfortunate for you, and I’d suggest looking into wasm.
Either way, this isn’t the right venue for this discussion - web browsers’ choices are their own, and this discourse is only for the JS language itself, which has no ability to force itself to be implemented anywhere. You may want to look at WHATWG.
I have complete control of what goes to my web server. Nobody else can see that code even if I choose to use an interpreted language like PHP, Python, or Ruby. I also have the choice to use a compiled language like C.
There was a proposal for effectively that but it hasn't made much progress. GitHub - tc39/proposal-binary-ast: Binary AST proposal for ECMAScript
I'm not sure what the browsers latest thoughts on that proposal are.
