Java and JavaScript Support for Microsoft Visio: Many UML diagramming tools are not backward compatible which requires software developers to redraw their diagrams with each new version of the tool. On the other hand, Microsoft Visio is a diagramming tool that has almost always been backward compatible but unfortunately does not include support for Java or JavaScript. From this article you can download two files that add Java and JavaScript support to Visio which will enable you to draw UML diagrams based on Java and JavaScript that won't have to be redrawn in years to come.

Six Functions Missing from JavaScript Arrays: Describes and implements six useful functions missing from the JavaScript Array class. The six missing functions are linearSearch, binarySearch, addAll, retainAll, removeAll, and unique. Shows how to add and use these functions in your JavaScript code.
Computing Statistics in JavaScript: Describes and implements a JavaScript class that uses numerically stable algorithms for computing eight statistics (count, sum, minimum, maximum, median, mean, variance, and standard deviation) of a series (array) of numbers. Shows how to add and use this class in your JavaScript code.
