这是我的解决方案

let zip = (a, b) => (a.length < b.length
  ? a.map((e, i) => [e, b[i]])
  : b.map((e, i) => [a[i], e]))

如果你喜欢ES6:

const zip = (arr,...arrs) =>(
                            arr.map(
                              (v,i) => arrs.reduce((a,arr)=>[...a, arr[i]], [v])))

你可以使用ES6来创建实用函数。

控制台。json = obj => console.log(json .stringify(obj)); Const zip = (arr，…arrs) => 加勒比海盗。Map ((val, i) => arrs。Reduce ((a, arr) =>[…]A, arr[i]]， [val])); / /实例 Const array1 = [1,2,3]; Const array2 = ['a'，'b'，'c']; Const array3 = [4,5,6]; 控制台。json (zip (array1 array2));/ /[[1, "一个"],[2,“b”],[3,“c”]] 控制台。Json (zip(array1, array2, array3));/ /[[1”“4],[2“b”5],[3“c”6]]

但是，在上述解决方案中，第一个数组的长度定义了输出数组的长度。

这里有一个解决方案，你可以更好地控制它。这有点复杂，但值得。

function _zip(func, args) { const iterators = args.map(arr => arr[Symbol.iterator]()); let iterateInstances = iterators.map((i) => i.next()); ret = [] while(iterateInstances[func](it => !it.done)) { ret.push(iterateInstances.map(it => it.value)); iterateInstances = iterators.map((i) => i.next()); } return ret; } const array1 = [1, 2, 3]; const array2 = ['a','b','c']; const array3 = [4, 5, 6]; const zipShort = (...args) => _zip('every', args); const zipLong = (...args) => _zip('some', args); console.log(zipShort(array1, array2, array3)) // [[1, 'a', 4], [2, 'b', 5], [3, 'c', 6]] console.log(zipLong([1,2,3], [4,5,6, 7])) // [ // [ 1, 4 ], // [ 2, 5 ], // [ 3, 6 ], // [ undefined, 7 ]]

这将从Ddi基于迭代器的答案中删除一行:

function* zip(...toZip) {
  const iterators = toZip.map((arg) => arg[Symbol.iterator]());
  const next = () => toZip = iterators.map((iter) => iter.next());
  while (next().every((item) => !item.done)) {
    yield toZip.map((item) => item.value);
  }
}

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。

没有等价的函数。如果你只有几个数组，你应该使用for循环获取一个索引，然后使用索引访问数组:

var array1 = [1, 2, 3];
var array2 = ['a','b','c'];

for (let i = 0; i < Math.min(array1.length, array2.length); i++) {
    doStuff(array1[i], array2[i]);
}

如果你有更多的数组，你可以在数组上有一个内循环。
