Hello experts,

Can you what is difference between String literal and String object? And the advantages & dis-advantages of both.

I know

s1 = "s1" //String Literal
s2 = new String("s2") //String object

But I don't know where to use what?

Thanks

==================================================
// try this code
s1 = "s1" //String Literal
s2 = new String("s2") //String object

trace("is s1 an instance of String Class? " + (s1 instanceof String))
trace("is s2 an instance of String Class? " + (s2 instanceof String))

trace("s1 datatype is " + (typeof s1))
trace("s2 datatype is " + (typeof s2))
==================================================

actually, the first is not generated from the String Class, and appears to be of "string" datatype.
the second is an instance of String Class, thus an object.
beside that, they behave the same (usually people use the first for brevity reasons)

(it's just like gotoAndPlay global function and gotoAndPlay Movieclip method)
