Can a JavaScript object property refer to another property of the same object?
I recently tried to create an object like this: var carousel = { $slider: $('#carousel1 .slider'), panes: carousel.$slider.children().length }; My intentions were to improve jQuery's selector performance by caching the results of $('#carousel1 .slider') in an object property, and to keep the code concise and relatively...

Clean Code: Should Objects have public properties?
I'm reading the book "Clean Code" and am struggling with a concept. When discussing Objects and Data Structures, it states the following: Objects hide their data behind abstractions and expose functions that operate on that data. Data Structures expose their data and have no meaningful functions. So, what I'm getting from this is th...

Cannot Convert ref double[] to ref object
It seems like I'm on here asking a question just about every day now. I'm not sure if that's a good thing or a bad thing...
