Answer 1

There are many professional quality front ends that compile into optimised JavaScript.

IntelliJ IDEA can convert any Java code that you paste into a Kotlin buffer.

Every compiler that emits executable at the end is capable of producing assembly for the target platform.

Until g++ came along, C++ was compiled to C and then a C compiler took over from there. So if you can access old compilers, from some 20 years ago,..

Many template engines produce HTML and other things. Jinja, JSP come to the top of the mind.

Every lisp out there has a macro system that can produce compilable or interpretable code.

I'm sure I'm missing many more.
