IW 17 vs TMS Software's Web Core

[Alexandre Machado]

I'll finish saying that.... well... a small comparison:
 

IW                                          TMS Web 

Is Delphi                                  Is not Delphi

Your code is Delphi                   Your code is some Pascal dialect (AFAIK compatible with Delphi 7, no generics and things you take for granted today)

Your application is Delphi           You get HTML + JS files. I'm not sure the word "application" applies here

All your Delphi code work          "There is a basic Object Pascal RTL". Maybe your code works, maybe not.

You debug in Delphi IDE            You debug in the browser (more about this later)

Your IP is as secured as in         Everything TMS Web generates as output cannot be protected 

   any Delphi app

It is *real* Delphi                      Just pretends to be Delphi   

Quoted from pas2js Free Pascal Wiki (pas2js is the pascal to javascript transpiler used by TMS web), emphasis is mine:

Debugging
The generated Javascript source code is of course visible and debuggable in the browser.
Moreover, the transpiler can generate a source map, which means that you will be able to see and debug the Pascal code in the browser. (not everything will work, but many things do. This depends on the browser too.)
