Not quite sure if the empty string (`console.count("")`) should show `: 1` or if it should be equivalent to `console.count()`.

What if the argument is all whitespace?

Looks like a good change, but the corresponding test needs to be rebaselined and edited to cover this change. The test is LayoutTests/inspector/console/console-api.html.

Please add the following cases (at least) to the test, to cover the counting functionality and the handling of whitespace/empty arguments.

console.count() // second time
console.count("")
console.count("    ")
console.count("") // second time
console.count("    ") // second time
console.count("counter title")
console.count("counter title") // second time

We should probably also add test cases for passing null, undefined, object, number to console.count() to document what it does.

I think we should match what Chrome / Firefox does. This is mainly implemented in Web Inspector for compatibility with other devtools.

[Johan K. Jensen]

Both Firefox and Chrome has `console.count()` and `console.count('')` be equivalent (i.e. the count would be 2 after running those commands), while any additional whitespace to the title-parameter would create new counters.
Firefox also writes "<no label>: x" for counters without a title or with the empty title (but not for whitespace).
Should WebKit also show "<no label>: x" for those two cases? (And if so, should it be localized? And how would I do that?) Or should it just show "x"?

Yes, let's match what they do. I think it looks kind of dumb (do you have a better idea?) but showing nothing is even worse.

Don't worry about localizing this; none of the console messages are currently localized. They should be localized, but that should be addressed in a separate bug.

I've been wondering for a while now if we should just drop console.count. Last I checked, no browser implements a sufficiently useful version of it. They all track just line number, so in minified sources it is completely useless as all counts() are considered the same line.

Has this grown in popularity somewhere? Is there a good use case for it?

r=me, This is looking great. Thanks for updating the test!

I've seen people use console.count("method name") for some basic profiling, e.g.:

function foo() {
    console.count("foo")
    ...
}

function bar() {
    console.count("bar")
    ...
}

We could draw charts for console.count:

foo: 42 ****************
bar: 10 ****

I'd use it.

I don't know where would we put this in the UI though.
