There is also a console load() function that takes as an argument the
path to a JavaScript source file to load and evaluate.

Thanks Kevin. I missed that.

... haven't spend time on this... but “load” is actually just a
function of js, much like “include” in other lang.

i'm hoping to have something like eval-region and eval-buffer for it.
Using the “load” function to implement this might mean a bit of a
hack.

... looking at the source code, looks like js-evaluate in the right
thing to call. Just did this:

(js-evaluate "print(4);")

4

seems it insert result and consol prompt into the current buffer, as
if expecting it is called in a console... a bit more look i found js-
eval-buffer:

// (js-eval-buffer (current-buffer))
print(3);

but got error
let: No catch for tag: js-THROW, throw

So you need to establish the js-THROW tag before calling js-eval-buffer:

(catch 'js-THROW
  (js-eval-buffer (current-buffer)))

If you search the ejacs source code for js-THROW and js-eval-buffer, you
should be able to find out how to do it properly.
