JavaScript closures vs. anonymous functions
A friend of mine and I are currently discussing what is a closure in JS and what isn't. We just want to make sure we really understand it correctly. Let's take this example. We have a counting loop and want to print the counter variable on the console delayed. Therefore we use setTimeout and closures to capture the value of the counter variable to make sure that it will not print N times the value
Why does this code using random strings print "hello world"?
The following print statement would print "hello world". Could anyone explain this? System.out.println(randomString(-229985452) + " " + randomString(-147909649)); And randomString() looks like this: public static String randomString(int i) { Random ran = new Random(i); StringBuilder sb = new StringBuilder(); while (true) { int k = ran.nextInt(27); if (k == 0) break; sb.append((char)('`' + k)); } r

Why does Google prepend while(1); to their JSON responses?
Why does Google prepend while(1); to their (private) JSON responses?

How to document CoffeeScript source code with JSDoc?
I have some code written in CoffeeScript and I want to optimize the generated JavaScript with the Google Closure Compiler, so these files need to be documented with JSDoc. My question is, how can I document the *.coffee files to generate javascript containing working JSDoc for the closure compiler? One more question: is there a way to keep a single-line comment in *.coffee ?
How do I verify jQuery AJAX events with Jasmine?
I am trying to use Jasmine to write some BDD specs for basic jQuery AJAX requests. I am currently using Jasmine in standalone mode (i.e. through SpecRunner.html). I have configured SpecRunner to load jquery and other .js files. Any ideas why the following doesn't work? has_returned does not become true, even thought the "yuppi!" alert shows up fine. describe("A jQuery ajax request should be able t
