In this talk these and more comparisons will be drawn between the two languages. The main weaknesses and strengths of JavaScript will be discussed and compared to PHP. Examples will be given of closures and lambda functions in JavaScript and they will be compared to the implementation of these same features in the upcoming PHP 5.3.
