Loose Typing in Javascript

What is Loose Typing?

Well, this seems like a good place to start. It is important to understand both what loose typing is, and what loose typing is not. Loose typing means that variables are declared without a type. This is in contrast to strongly typed languages that require typed declarations.

Consider the following examples:

  1. /* JavaScript Example (loose typing) */  
  2. var a = 13; // Number declaration  
  3. var b = “thirteen”; // String declaration  
  5. /* Java Example (strong typing) */  
  6. int a = 13; // int declaration  
  7. String b = “thirteen”; // String declaration  

Notice that in the JavaScript example, both a and b are declared as type var. Please note, however, that this does not mean that they do not have a type, or even that they are of type “var”. Variables in JavaScript are typed, but that type is determined internally. In the above example, var a will be type Number and var b will be type String. These are two out of the three primitives in JavaScript, the third being Boolean.

Microsoft recently (12-29-2011) released an update to address several serious security vulnerabilities in the .NET Framework. One of the fixes introduced by MS11-100 temporarily mitigates a potential DoS attack involving hash table collisions. It appears this fix breaks pages that contain a lot of POST data. In our case, on pages that have very large checkbox lists. Why would this be the case?

Some non-official sources seem to indicate that MS11-100 places a limit of 500 on postback items. I can’t find a Microsoft source that confirms this. I know that View State and other framework features eat up some of this limit.
