...;IsJSObject()) { JSObject::OptimizeAsPrototype(Handle<JSObject>::cast(value)); } Which in turn is called by FuntionSetPrototype which is what we get with .prototype =. Doing __proto__ = or .setPrototypeOf would have also worked but these are ES6 functions and Bluebird runs on all browsers...

...s a lot of complexity into the implementation. This complexity impacts casting, layout, dispatch, field access, serialization, identity comparisons, verifiability, reflection, generics, and probably lots of other places. You can read the full article here. For Java, you can read th...

...te code, like Number(value), it’s called explicit type coercion (or type casting). Since JavaScript is a weakly-typed language, values can also be converted between different types automatically, and it is called implicit type coercion. It usually happens when you apply operators to values of diff...

... change the compile time type of the object to IQueryable. You could just cast it, but by having an AsQueryable method you can take advantage of type inference. This is simply more convenient if the generic argument list is complex, and it is actually necessary if any of the generic arguments are ...

...he class' v-table, each slot has a pointer to one of the virtual methods. Casting an object to an interface type generates a pointer to the section of the table that implements the interface methods. The client code that uses the interface reference now sees the first interface method pointer at o...

...act of that is the behavior you see where you get different results if you cast to an interface. share | improve this answer | follow | ...

..., and (2) an unfortunate extra layer of boxing indirection any time it was cast to Object. Given that the heap representation of string is unique, having special treatment to avoid extra boxing wouldn't have been much of a stretch (actually, being able to specify non-default boxing behaviors would ...

... @ARW "PHP seems to cast everything to an int in an array definition if it can." - yep, that's exactly what happens. The biggest WTF is that it even does this to floats; if you try var_dump([1.2 => 'foo', 1.5 => 'bar']); you'll discover th...

...heard what my co-worker said to a Java lecturer after he was introduced to casting for the first time (at this point he only knew Haskell) - "What?! You mean you've got something and you don't KNOW what type it is?!" – Jacob Stanley Aug 27 '09 at 13:56 ...

...instead of explicitly adding the offset to the pointer returned by malloc, cast to char *, is irrelevant. Technically, p->s[0] is the single element of the char array inside the struct, the next few elements (e.g. p->s[1] through p->s[3]) are likely padding bytes inside the struct, which c...
