ZGRViewer is a 2.5D graph visualizer implemented in Java and based upon the Zoomable Visual Transformation Machine. It is specifically aimed at displaying graphs expressed using the DOT language from AT&T GraphViz and processed by programs dot, neato or others such as twopi.

there is a little bit of hand-waving involved in calling JavaScript a functional language. JavaScript is not a side-effect free language, nor is it an expression-based language (i.e., it is not value-oriented, but rather variable-oriented). There is no tail call optimization in any of the current implementations, so recursion must be kept shallow. And the list goes on. Truth be told, JavaScript is really one of the first hybrid imperative-functional languages.

Higher-order functions allow us to do functional composition,

Since JavaScript does not have "overloaded" functions, this type of functionality is usually simulated using manipulation of the function's arguments. Currying comes in handy because it allows you to do this manipulation in a much cleaner and more modular way.

  LINQPad lets you interactively query SQL databases in a modern query language: LINQ.  Kiss goodbye to SQL Management Studio!

it's a highly ergonomic code snippet IDE that instantly executes any C#/VB expression, statement block or program – the ultimate in dynamic development.

Best of all, LINQPad standard edition is free and can run without installation (or with a low-impact setup)

function ZParenizor2(value) { var that = new Parenizor(value); that.toString = function () { if (this.getValue()) { return this.uber('toString'); } return "-0-" }; return that; }

Again, we augment Function. We make an instance of the parent class and use it as the new prototype. We also correct the constructor field, and we add the uber method to the prototype as well.

This adds a public method to the Function.prototype, so all functions get it by Class Augmentation. It takes a name and a function, and adds them to a function's prototype object.
