How to create your own helpers 1.1

...How would you achieve the example in the op, but with a callback?

You could use something like I do in this post:
xenForo variables in Javascript

Do you always have create an add-on just create a helper? Or can they added elsewhere?

Thank you

Another great tutorial, thanks!

"echo" in the $helperCallbacks array is just the name of your particular custom helper, right? One thing you might want to mention - it seems this name cannot contain a capital letter. I nearly went crazy trying to figure out why my custom helper didn't work, and that was it - I had named it after the method which did its calculation, which contained a capital letter in camel case.

Should a custom helper always return a string?

I coulda sworn this thread was locked earlier :S (sorry for the report)

Anyway.... @Fuhrmann could the tutorial point out that helper names must be in lower case? I spent hours yesterday cussing you whilst trying to get "myHelper" to work until I went back to the drawing board and then realised they must have to be all lower case.

Is anyone able to go more in depth on this now that callbacks would appear to be a better alternative?

PLEASE update to say that the name has to be lowercase. I, too, spent far too long trying to figure out what I did wrong... I spent over twice the amount of time trying to debug this than I spent actually creating the helper. Please add something in the tutorial about lowercase. It's essential.
