Faster Functional Methods for Array and Vector

Tags: , , , , , , , ,

Four years ago I tested the functional programming-style methods of Array and Vector: every, filter, forEach, map, and some. In that article I showed that these functions are much slower than doing the same task through traditional loops. Today’s article seeks to improve the performance of the functional methods while retaining readability by using ASC 2.0’s [Inline] metadata. Can homemade versions of these functions beat the built-in ones from Adobe? Read on to find out!

Functional Methods

Tags: , , , , ,

Both Array and Vector have some methods that allow AS3 programmers to do some functional programming: every, filter, forEach, map, and some. These can lead to flexible and concise code, but at what performance cost? Today I’ll test them to get a handle on just how much speed you’re giving away by using these methods.
