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': 'B',
'3': 'C',
'4': 'D',
'5': 'E',
}
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);
.forEach is a loop.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;
});
$.each() is not a loop anymore :)?
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);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 = new Proxy({}, {
set: function(target, prop, value, receiver) {
target[array1[prop]] = value;
return true
}
});
const output = Object.assign(combineKeyValueProxy, array2);
console.log(output) // Proxy {1: "A", 2: "B", 3: "C", 4: "D", 5: "E"}
