Details

:: Developer Documentation Request Request Type: Correction Gecko Version: unspecified Technical Contact: :: Details Quote: "The copyWithin works like C and C++'s memcpy..." No, it doesn't. An important aspect of memcpy is that it doesn't support overlapped regions, whereas copyWithin explicitly does. For developers with C/C++ knowledge, it would be much better to state: "The copyWithin works like C and C++'s memmove..." - memmove is specifically designed to allow overlapped regions in the source and destination.
thanks! fixed https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/copyWithin
