My Life and Code

Recently I was working on a website using Angular.js and needed to make use of the ngRepeat directive to iterate through a collection of objects. The UI in question needed to allow the user to select a child object, contained in an array, from one of the objects being displayed. And to provide a better user experience, I decided to only show those objects where the aforementioned array contained at least one object to select. Here's how I accomplished this using Angular's filtering capabilities, where elements  is the name of the property containing the child objects to choose from: <div ng-repeat="section in allSections | filter:{elements: []}:false"> Hopefully this will help someone trying to do something similar. :)

I recently wrote the following line of code: newsletterPopupEnabled = Boolean($("#newsletterPopupEnabled").val()); The point of this was to correctly parse a string of "true" or "false", as well as to take into account an empty string (which I expected to be interpreted as false). I was very wrong. The Boolean() function does not parse a string, but simply tests the truthiness of the parameter passed to it. So, a string of "false" is interpreted as truthy because the string is not null. I now go to ponder the true meaning of "truth"... :)
