sequence

sequence()

Creates an Asynchronous Stack which execute each enqueued method after the previous function calls the provided next(err, data [, ...]).

Core

• Futures.sequence(globalContext=null)
• then(next, err, data [, ...]) - add a method onto the queue
  • begins or resumes the queue
  • passes the results of the previous function into the next

Example:

var sequence = Futures.sequence(),
  err;

sequence
  .then(function (next) {
    setTimeout(function () {
      next(err, "Hi", "World!");
    }, 120);
  })
  .then(function (next, err, a, b) {
    setTimeout(function () {
      next(err, "Hello", b);
    }, 270);
  })
  .then(function (next, err, a, b) {
    setTimeout(function () {
      console.log(a, b);
      next();
    }, 50);
  });
