flexjs init the int =0
as3 code
var i:int
the (i=0)
but js code
var i;
the(i = NaN)
so good js code is var i =0;

We had a discussion a few months back entitled "[FlexJS]as in”. There were a number of suggestions how to handle int, but I don’t think anyone did anything there.

in as3 if you sign an object to an int an error is thrown. in js the
variable would be assigned to the object and would no longer be an int. so
maybe, when the time comes, simply casting it as int would be enough.

IMO, it should be easy to initialize integers to zero, but I'm concerned
about the overhead of having to do all of the automatic type conversions
that AS does and JS doesn't, so injecting code like parseInt will probably
have to wait.

ihzi is correct. to clarify, the compiler should initialize integers to
zero when they are defined. and it should probably wrap any code that
assigns a value to an int with parseInt().

Forgot about that. I'm just used to always initializing my ints/numbers to 0 or -1.

A Number initializes to NaN in the Flash runtimes, if you don't set it to
anything else.

Yep. Looking into it. Are there any other types other than int and uint

Re: flexjs init the int =0

in as3
var i:int; // i equals 0
in JavaScript i is undefined because we don't know what type it is
var i; // null, undefined or NaN
therefore we need to initialize every integer as zero when it's defined.
