So you say EvertJan was wrong the script is not compiled?

Even this sentence is gramatically insufficient without a comma,
it is impossible to reliably detect what you mean, 
so one can only guess.

I am often wrong, but not often so wrong that you, Jonas could detect that.

Adobe Phonegap is a tool to build applications for mobile devices using 
JavaScript and HTML and uses Cordova.

Cordova runs on Node.js

Node.js® is a JavaScript runtime built on Chrome's V8 JavaScript engine

Chrome's V8 JavaScript engine runs Javascript source.

Look for yourself how Cordova works - thank you.

Compiled code is safer than script :
  (1) It cannot easily be edited,
  (2) It cannot easily be read,
  (3) It uses the CPU and the OS, but is safe against browser variations.


Re (2) A long time ago, I requested and received some Pascal source code to study and maybe use.  The compiler could read it; but the variable names and comment were in Hungarian. :-(

But unsafer in modern times, John,
as malicious code can more easily be hidden inside.

[It seems the definition of "safer" has shifted!

You would still need some interface to the DOM,
when using a browser environment.

Perhaps it looked like intermediate P-code,
but in fact being Hungarian assembler-code:

"egy, ketto, három, négy, öt, hat, hét, nyolc, kilenc, tíz"

[I learned this from my father, who again got it from his parents's 
Hungarian maid around 1918. They, those maids, were cheap at that time, 
having escaped the famine overthere.]

True.  But script can easily be made malicious, by simply subtly
changing a calculation to give plausible but incorrect answers -
or, sometimes, by changing   new Date(0)   to   new Date()   -
or even by using a different browser.

I presumed that compiled executable code would not be for running
(how?) in a browser.

No, it was perfectly normal Pascal code, but with unpronounceable
variable names and unreadable comment (except that it might have
been Algol 60 (I knew which it was at the time)).  It was, however,
mathematically clever (for its time), which is why I asked for it.

I've searched for it some years ago and couldn't find any.

That NectarJS seems to be a new project. The compiling part is almost
perfect, because it produces Windows EXE files which are not entirely valid
(miscalculated field value(s) in PE header). The JavaScript part seems to be
at an early stage, considering that the try-catch exception handling has not
yet fully functional. But the project's future is promising. Worth to wait
for.

With Electron, one can build desktop apps using JS / Node.js, HTML and CSS:

Electron doesn't actually compiles the JavaScript code. It merely bundles
the JavaScript code with native application which uses embedded web browser
to run the JavaScript code.
