Please don't fancy functional programming in javascript. Its a powerful paradigm and should be used in a language with powerful compiler.

  JavaScript compilers are about the most powerful ones out there.

    Sorry. I should have shared the example I was thinking of as well. Just my example. [lengthy_array].map(function).filter(function).reduce(function). JS compiler just runs them. A compiler to be powerful to handle such functional programming syntax should also have ability to inline the functions as a single function. the above example could be recompiled as [lengthy_array].array_operation(Three function composed into one)

      Oh, forgot to answer here. As a compiler developer I'm very surprised by the assertion that this wouldn't be optimized by something like V8 or GraalVM's JavaScript engine. But I couldn't JavaScript myself out of a paper bag, so I don't know how to verify this myself.
