Class Detail

Pot.Deferred#zip((callback), (context))

Create a new array which has the elements at position ith of the provided arrays. This function is handled as seen from the longitudinal for array that is similar to the zip() function in Python.

Example:

  arguments:  [[1, 2, 3],
               [4, 5, 6]]

  results:    [[1, 4],
               [2, 5],
               [3, 6]]

  var d = new Deferred();
  d.then(function() {
    return [[1, 2, 3], [4, 5, 6]];
  }).zip().then(function(res) {
    debug(res);
    // @results
    //     [[1, 4], [2, 5], [3, 6]]
    //
  }).begin();

  var d = new Deferred();
  d.then(function() {
    return [[1, 2, 3], [1, 2, 3, 4, 5]];
  }).zip().then(function(res) {
    debug(res);
    // @results
    //     [[1, 1], [2, 2], [3, 3]]
    //
  }).begin();

  var d = new Deferred();
  d.then(function() {
    return [[1, 2, 3], [4, 5, 6], [7, 8, 9], [10, 11]];
  }).zip().then(function(res) {
    debug(res);
    // @results
    //     [[1, 4, 7, 10], [2, 5, 8, 11]]
    //
  }).begin();

  begin(function() {
    return ['hoge'];
  }).zip().then(function(res) {
    debug(res);
    // @results
    //     [['hoge']]
    //
  });

  begin(function() {
    return [[1], [2], [3]];
  }).zip().then(function(res) {
    debug(res);
    // @results
    //     [[1, 2, 3]]
    //
  });

  begin(function() {
    return [[1, 2, 3], ['foo', 'bar', 'baz'], [4, 5]];
  }).zip().then(function(res) {
    debug(res);
    // @results
    //     [[1, 'foo', 4], [2, 'bar', 5]]
    //
  });

  var callback = function(items) { return items[0] + items[1]; };
  begin(function() {
    return [[1, 2, 3], [4, 5, 6]];
  }).zip(callback).then(function(res) {
    debug(res);
    // @results [5, 7, 9]
  });

Parameters:
{Function} (callback): (Optional) Callback function. function({Array} items[, {*} object]) this == `context`.
{*} (context): (Optional) Object to use as `this` when executing callback.

Returns:: {Array} A new array of arrays created from provided objects.
