A trivial implementation of Reactive Demand Programming

I wrote a trivial implementation of RDP in JavaScript to help me understand how it works.

It's called bucky-rdp (about 200 lines of heavily commented code).

It currently supports Sirea's bconst, bpipe, and bfmap.

Here's an example:

// Create some behaviors for transforming numbers.
var bDouble = rdp.bFMap(function(val) { return val * 2; });
var bMinusOne = rdp.bFMap(function(val) { return val - 1; });

// Create a pipeline behavior of the two behaviors
var myBehavior = rdp.bPipe(bDouble, bMinusOne);

// Apply an inactive input signal to the pipeline behavior
var sigIn = rdp.makeSignal();
var sigOut = rdp.apply(myBehavior, sigIn);

// Change the input signal value and watch the output signal change
sigIn.setValue(2);
console.log(sigOut.getValue()); // Prints 3
sigIn.setValue(4);
console.log(sigOut.getValue()); // Prints 7
sigIn.deactivate();
