Question about question mark in JavaScript

[Jimolo]

Hi

What does a questionmark before a variable do?

For instance,

var test1 = ''

var test2 = '?test1'

What does it do?

 

[The Natural Philosopher]

In what context do you mean this?
Normally I would say its a query after an URL like;

three meanings in my 'bible'

the one you stated..URL stuff.

Then teh normal C style compact condtional as in

a=(b==c)?d:e;

(if b equals c, set a to d, else set a to e)

Or a part of a regexp pattern matching string thing.

Here? test2 contains the string "?test1". There is no "question mark
before a variable".
