php.js

isn't this more simple and functional? function sum (array) { return array.reduce(function (a, b) { return a + b; })} sum([1,2,3])

@pabrams: thanks. I've modified the function to make it more readable and got rid of most lint warnings. Updated code available on github (https://raw.github.com/kvz/phpjs/master/functions/var/empty.js)

Hi, for the first two js lint issues, try some carriage returns. Line #26 will also be much easier to read, especially if you format it nicely. Each new line after if (mixed_var === "" could start with a constant number of tabs and then || ... [More] mixed_var === . How 'bout that? Personally, I find code like line #26 to be inexcusable because it's a real pain to read, and very easy to avoid, if using a decent editor. [Less]

@David: Thanks for the fix with the missing userdata argument. I changed it a bit to check for arguments.length (number of arguments passed), since otherwise, it won't allow explicit passing of "undefined" as an argument. I also added support for ... [More] closures and PHP-style object-function arrays, added an option to avoid eval (not on by default since eval() is more PHP-like in allowing calls to built-in functions), and provided support within array() for walk() as a chainable method. Changes are in Git (see "raw js source"). [Less]

Line 21 doesn't make any sense, you are only passing userdata to the function, and userdata is undefined. Line 21 should be: eval(funcname + '(array[key] , key)');

I found bug with count of parameters for this function. So if we set over than 2 arguments - function returns empty object. You can test own example with colors on this page.
