This short video shows how a switchyard of if/elseif statements was converted to a simple formula. Testing of this refactoring was also done. if (typeof(playerLoaded) === ‘undefined’) {var… read more >>

Imagine you have a matrix, and you want to make a subset of that matrix that has only the rows that have a 2 in the first column. This is how you would do… read more >>
