Create Object From Two Arrays

How can I create an object from two arrays without using loops in javascript. example: array1 = [1,2,3,4,5]; array2 = [A,B,C,D,E]; I want from below object obj = { '1': 'A', '2':

Solution 1:

var obj = {}

array1 = [1, 2, 3, 4, 5];
array2 = ['A', 'B', 'C', 'D', 'E'];

array1.forEach(function(value, index) {

  obj[value] = array2[index];

});

console.log(obj);

Solution 2:

Try to use $.each() to iterate over one of that array and construct the object as per your requirement,

var array1 = [1,2,3,4,5],array2 = ['A','B','C','D','E'];
var obj = {};

$.each(array2,function(i,val){
  obj[array1[i]] = val;
});

DEMO

Solution 3:

An ES6, array reduce solution.

const array1 = [1, 2, 3, 4, 5];
const array2 = ['A', 'B', 'C', 'D', 'E'];
const resultMap = array1.reduce(
  (accumulator, value, index) =>Object.assign(accumulator, {
    [value]: array2[index],
  }), {}
);

console.log(resultMap);

Solution 4:

just for fun created something like this without using any iteration methods.

const array1 =  [1,2,3,4,5];
const array2 = ['A','B','C','D','E'];
let combineKeyValueProxy = newProxy({}, {
    set: function(target, prop, value, receiver) {
       target[array1[prop]] = value;
       returntrue
    }
});
const output = Object.assign(combineKeyValueProxy, array2);
console.log(output) // Proxy {1: "A", 2: "B", 3: "C", 4: "D", 5: "E"}
