Reset C int array to zero : the fastest way?
...);
It is also worth noting that specifically for objects of scalar types one can implement a type-independent macro
#define ZERO(a, n) do{\
size_t i_ = 0, n_ = (n);\
for (; i_ < n_; ++i_)\
(a)[i_] = 0;\
} while (0)
and
#define ZERO_A(a) ZERO((a), ARRAY_SIZE(a))
turning the abo...

What is the meaning of polyfills in HTML5?
...polyfill (adapter.js in the example) has replaced this object with its own one.
The one it has replaced it with is a shim. This will detect if the feature is natively supported and use it if it is, or it will work around it using other APIs if it is not.
So a polyfill is a sort of "transparent" s...
