What's the difference between using “let” and “var”?
...tatement.
If you're writing client-side JavaScript code and use a browser based transpiler (like Traceur or babel-standalone), you can safely use the let statement, however your code is likely to be anything but optimal with respect to performance.
If you're writing client-side JavaScript code and...
Why aren't variable-length arrays part of the C++ standard?
...ed-size. The C++ Dynamic Array proposal is intended to introduce a library based solution, as alternative to a language based VLA. However, it's not going to be part of C++0x, as far as I know.

PHP is still based heavily on the CGI protocol, most of the content of $_SERVER is straight from the CGI spec. And "CGI programming" always did mean the program processing the request, not the implementation of the protocol itself. If you...

Explicitly calling return in a function or not
... version 2.15
The picture above may slightly difffer on your platform.
Based on measured data, the size of returned object is not causing any difference, the number of repeats (even if scaled up) makes just a very small difference, which in real word with real data and real algorithm could not b...
Why and How to avoid Event Handler memory leaks?
...sion?
But, there are lots of events and event handlers in your whole code-base. Does it mean, you need to keep detaching event handlers everywhere? The answer is No. If you had to do so, your codebase will be really ugly with verbose.
You can rather follow a simple flow chart to determine if a de...
