Functional Reactive Programming (FRP) is a programming paradigm for working with time-varying values, better capturing the temporal aspect of mutable state. Signal is a data structure representing a time-varying value. For example, consider the position of the mouse. The signal mousePosition represents current mouse position. When the mouse moves, the value changes automatically.

Signals can also be transformed and combined without typical hazards of the stateful programs.

Example

Signal is very low level construct that can be used to create signals from scratch:

var signal = require("signalize/core").signal
var time = signal(function(next) {
  setInterval(function() {
    next(Date.now())
  }, 1000)
})

Signals can be spawned in order to consume it's changes:

var spawn = require("signalize/core").spawn

spawn(time, function(value) {
  console.log(value)
})
