除了ninjagecko出色而全面的回答外，将两个js数组压缩成“元组模拟”所需要的是:

//Arrays: aIn, aOut
Array.prototype.map.call( aIn, function(e,i){return [e, aOut[i]];})

Explanation: Since Javascript doesn't have a tuples type, functions for tuples, lists and sets wasn't a high priority in the language specification. Otherwise, similar behavior is accessible in a straightforward manner via Array map in JS >1.6. (map is actually often implemented by JS engine makers in many >JS 1.4 engines, despite not specified). The major difference to Python's zip, izip,... results from map's functional style, since map requires a function-argument. Additionally it is a function of the Array-instance. One may use Array.prototype.map instead, if an extra declaration for the input is an issue.

例子:

_tarrin = [0..constructor, function(){}, false, undefined, '', 100, 123.324,
         2343243243242343242354365476453654625345345, 'sdf23423dsfsdf',
         'sdf2324.234dfs','234,234fsf','100,100','100.100']
_parseInt = function(i){return parseInt(i);}
_tarrout = _tarrin.map(_parseInt)
_tarrin.map(function(e,i,a){return [e, _tarrout[i]]})

结果:

//'('+_tarrin.map(function(e,i,a){return [e, _tarrout[i]]}).join('),\n(')+')'
>>
(function Number() { [native code] },NaN),
(function (){},NaN),
(false,NaN),
(,NaN),
(,NaN),
(100,100),
(123.324,123),
(2.3432432432423434e+42,2),
(sdf23423dsfsdf,NaN),
(sdf2324.234dfs,NaN),
(234,234fsf,234),
(100,100,100),
(100.100,100)

相关的性能:

使用map over for loops:

请参阅:将[1,2]和[7,8]合并为[[1,7]，[2,8]的最有效方法是什么

注意:基本类型如false和undefined不具有原型对象层次结构，因此不公开toString函数。因此，这些在输出中显示为空。 由于parseInt的第二个参数是基数/数字基数，要将数字转换为基数/数字基数，并且由于map将索引作为第二个参数传递给它的参数函数，因此使用包装器函数。

Python有两个压缩序列的函数:zip和itertools.zip_longest。Javascript中相同功能的实现如下所示:

Python的zip在JS/ES6上的实现

const zip = (...arrays) => {
    const length = Math.min(...arrays.map(arr => arr.length));
    return Array.from({ length }, (value, index) => arrays.map((array => array[index])));
};

结果:

console.log(zip(
    [1, 2, 3, 'a'],
    [667, false, -378, '337'],
    [111],
    [11, 221]
));

[[1, 667, 111, 11]

console.log(zip(
    [1, 2, 3, 'a'],
    [667, false, -378, '337'],
    [111, 212, 323, 433, '1111']
));

[[1、667、111],[2,假的,212年],[3、-378、323],[' a ', “337”，433]]

console.log(zip(
    [1, 2, 3, 'a'],
    [667, false, -378, '337'],
    [111],
    []
));

Python的zip_longest在JS/ES6上的实现

(https://docs.python.org/3.5/library/itertools.html?highlight=zip_longest # itertools.zip_longest)

const zipLongest = (placeholder = undefined, ...arrays) => {
    const length = Math.max(...arrays.map(arr => arr.length));
    return Array.from(
        { length }, (value, index) => arrays.map(
            array => array.length - 1 >= index ? array[index] : placeholder
        )
    );
};

结果:

console.log(zipLongest(
    undefined,
    [1, 2, 3, 'a'],
    [667, false, -378, '337'],
    [111],
    []
));

[[1,667, 111, undefined]， [2, false, undefined, undefined]， [3， -378, undefined, undefined]， ['a'， '337'， undefined， 未定义

console.log(zipLongest(
    null,
    [1, 2, 3, 'a'],
    [667, false, -378, '337'],
    [111],
    []
));

[[1, 667, 111, null]， [2, false, null, null]， [3， -378， Null, Null]， ['a'， '337'， Null, Null]]

console.log(zipLongest(
    'Is None',
    [1, 2, 3, 'a'],
    [667, false, -378, '337'],
    [111],
    []
));

[[1,667, 111， 'Is None']， [2, false， 'Is None'， 'Is None']， [3, -378,“没有”,“没有 ' ], [ ' ”、“337”、“没有”、“ 没有']]

python zip函数的生成器方法。

function* zip(...arrs){
  for(let i = 0; i < arrs[0].length; i++){
    a = arrs.map(e=>e[i])
    if(a.indexOf(undefined) == -1 ){yield a }else{return undefined;}
  }
}
// use as multiple iterators
for( let [a,b,c] of zip([1, 2, 3, 4], ['a', 'b', 'c', 'd'], ['hi', 'hello', 'howdy', 'how are you']) )
  console.log(a,b,c)

// creating new array with the combined arrays
let outputArr = []
for( let arr of zip([1, 2, 3, 4], ['a', 'b', 'c', 'd'], ['hi', 'hello', 'howdy', 'how are you']) )
  outputArr.push(arr)

与其他类似Python的函数一样，pythonic提供了一个zip函数，其额外的好处是返回一个惰性求值迭代器，类似于Python对应的行为:

import {zip, zipLongest} from 'pythonic';

const arr1 = ['a', 'b'];
const arr2 = ['c', 'd', 'e'];
for (const [first, second] of zip(arr1, arr2))
    console.log(`first: ${first}, second: ${second}`);
// first: a, second: c
// first: b, second: d

for (const [first, second] of zipLongest(arr1, arr2))
    console.log(`first: ${first}, second: ${second}`);
// first: a, second: c
// first: b, second: d
// first: undefined, second: e

// unzip
const [arrayFirst, arraySecond] = [...zip(...zip(arr1, arr2))];

我是Pythonic的作者和维护者

我创建了一个简单的函数，通过一个选项来提供一个拉链函数

function zip(zipper, ...arrays) {
    if (zipper instanceof Array) {
        arrays.unshift(zipper)
        zipper = (...elements) => elements
    }

    const length = Math.min(...arrays.map(array => array.length))
    const zipped = []

    for (let i = 0; i < length; i++) {
        zipped.push(zipper(...arrays.map(array => array[i])))
    }

    return zipped
}

惰性生成器解决方案的一个变体:

function* iter(it) { yield* it; } function* zip(...its) { its = its.map(iter); while (true) { let rs = its.map(it => it.next()); if (rs.some(r => r.done)) return; yield rs.map(r => r.value); } } for (let r of zip([1,2,3], [4,5,6,7], [8,9,0,11,22])) console.log(r.join()) // the only change for "longest" is some -> every function* zipLongest(...its) { its = its.map(iter); while (true) { let rs = its.map(it => it.next()); if (rs.every(r => r.done)) return; yield rs.map(r => r.value); } } for (let r of zipLongest([1,2,3], [4,5,6,7], [8,9,0,11,22])) console.log(r.join())

这是python经典的“n-group”习语zip(*[iter(a)]*n):

triples = [...zip(...Array(3).fill(iter(a)))]
