Javascript ES6 - 映射多个数组 [英] Javascript ES6 - map multiple arrays

问题描述

有什么像拉链：

  var myFn = function（a，b）{console.log（a，b）;} 
 var arr1 = ['a'，'b'，'c ]; 
 var arr2 = [1，2，3]; 
 
 arr1.map（myFn，arr2）; //虚构语法
 //印刷品：
 // a 1 
 // b 2 
 // c 3 
  

解决方案

不幸的是没有。您要查找的内容通常称为 zip 或 zipWith 。请参阅lodash的实现以获得参考： https://lodash.com/docs#zipWith

Is there a feature in JavaScript 6 that allows to map over multiple arrays ?

Something like a zipper :

 var myFn = function (a, b) { console.log(a, b);}
  var arr1 = ['a', 'b', 'c'];
  var arr2 = [1, 2, 3];

  arr1.map(myFn, arr2); // imaginary syntax.
  // prints :
  // a 1
  // b 2
  // c 3

解决方案

Unfortunately, no. What you are looking for is commonly called zip or zipWith. See lodash's implementation for a reference: https://lodash.com/docs#zipWith
