What is the best-practice casing style for javascript? Why?
One aspect of javascript that it's hard to find information on is casing practices.

Parameter Checks vs Function Call Overhead
Hello, I have a public function that needs to check the validity of a few parameters, but this function is also used internally in a few others places in which I know that the given parameters will be valid.

C# will not allow to write non-member functions and every method should be part of a class. I was thinking this as a restriction in all CLI languages. But I was wrong and I found that C++/CLI supports non-member functions. When it is compiled, compiler will make the method as member of some unnamed class. Here is what C++/CLI standard ...

What happens when an inline function is passed as a parameter in C?
Today I was writing some C code to sort an array of structs using quicksort with a custom comparator function to determine their ordering.
