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
