Object comparison in JavaScript [duplicate]
... following objects:
x = {a: 1, b: 2};
y = {b: 2, a: 1};
2) Slow and more generic.
Compares objects without digging into prototypes, then compares properties' projections recursively, and also compares constructors.
This is almost correct algorithm:
function deepCompare () {
var i, l, lef...

...:data(condition),a:data(orCondition)") ... it'll have the same effect. The more features you add, the slower it'll be. If the logic is complex, then use $(foo).filter(function(){...}).

Way to go from recursion to iteration
.../ Push other objects on the stack as needed.
...
}
Note: if you have more than one recursive call inside and you want to preserve the order of the calls, you have to add them in the reverse order to the stack:
foo(first);
foo(second);
has to be replaced by
stack.push(second);
stack.push(first...

How can you do anything useful without mutable state?
...t just setting up all kinds of boundaries to purposefully make programming more difficult. My point of view, you're just experiencing the Blub paradox.
I was skeptical at first, but I jumped on the functional programming train a few years ago and fell in love with it. The trick with functional prog...
Easy way to prevent Heroku idling?
...ll ping your site twice per minute, thus preventing the dyno from idling.
More or less the same solution as Jesse but maybe more integrated to Heroku... And with a few perks (performance monitoring is just great).
Note: to all those saying it doesn't work: the important part in my answer is "...

OK, so you lose the ability to apply the same change to multiple branches by merging, but this is in any case the core of code where merging doesn't work very well. If you're having to m...
