Re: [royale-asjs] branch develop updated: Added debounceShort and debounceLong
It turns out that because of the way that Royale binds methods, there’s no need
to pass around “this” to these functions.
You can just do this:
var foo:Foo = new Foo();
var increment:Function = debounceShort(foo.increment,30);
And then happily call increment(n) and it’ll automatically just work on foo.
B-)
I also added a throttle function.
Having fun with this!

Re: [royale-asjs] branch develop updated: Added debounceShort and debounceLong
FYI:
“Debounce” is a term that AFAIK was made popular by underscore.
https://underscorejs.org/#debounce
There’s debounceLong which does the same thing as underscore’s default debounce
functionality. Royale's version also has the option to pass in a “this” object.
That’s necessary if you are debouncing a instance method which needs access to
“this”.
debounceShort is the same as debounceLong, but it debounces early like the
“immediate” option in underscore’s version.
I needed this functionality today, so I figured it’s time to start populating
functional utilities… ;-)
There’s “FunctionalTests” which show how to use it (sort of).
HTH,
