Some JavaScript questions

Since I never had close contact with javascript I would like to clarify some aspects:

  1. Whenever I’m assigning new
    instance of an object to a variable
    does the previous object is deleted
    as it happens in java (with help of
    garbage collector)?

  2. Can I declare a class as abstract
    one and there are interfaces in
    javascript? If the answer is yes
    then give me a little example,
    please. Just to see its syntax…

  1. I am not 100% sure here, I haven’t really dived into the UnityScript engine as of yet, but in Javascript and Actionscript 3 (both of which are based off of the ECMA Script standard), objects which have no references to them (orphaned variabled) are removed (or queued for removal) by the garbage collector; so I assume that it is the same here with UnityScript.

  2. As syclamoth stated, UnityScript is a unique version of Javascript (though it is closest to using the ECMA Script 4 standard – the same on that Actionscript 3.0 uses). You can create interfaces though, and it is pretty much exactly the same as in Java. Here is a quick interface example for UnityScript:

`
public interface MyInterface{

function GetMyName():String;

}`

To implement the interface you also do it like in Java:

`
class MyClass inplements MyInterface{

public function GetMyName():String{

return “BetaWar”;

}

}

`

Hopefully that helps.
