General (non-technical) Off-Topic

There were a couple of questions raised, partially it was due to a slight error that creeped into the code which has been fixed and acknowledged.

This article here tries to answer the same including what is the difference between the ‘.’ and the ‘:’ method of calling functions.

Read some posts on your blog:
http://howto.oz-apps.com/2011/09/wip-eval-routine-for-coronasdk.html

and eval is baaaaaaaddd, verrrryyyy bad function in javascript. Next thing is closures, real and fast closures like this:

[lua]local function Foo(arg)
…
return function() end
end[/lua]

Why you don’t use it in your examples? [import]uid: 12704 topic_id: 15527 reply_id: 57386[/import]

@gtatarkin,

  1. The eval routine which is Work In Progress was for a specific reason/request

  2. there are certain things that can only be resolved with eval

for instance, if I get from a user a string in resulting, that I wasn’t to evaluate, I cannot use inline functions to get the value, or can I?

For almost 10 years I work as webdeveloper. Using eval in JS is alway bad thing and there is always way to avoid it. [import]uid: 12704 topic_id: 15527 reply_id: 57404[/import]
