How to convert two arrays of strings to the array of objects like key and value with particular keys in javascript? [duplicate]

Question

I need to convert two arrays of strings with the same length:

const arr1 = ['Jessica', 'Ben', 'Samantha', 'John', 'Sandy'];
const arr2 = ['21', '45', '34', '90', '67'];

And in the end i need to get this array with particular keys name, age:

const result = [
{ name: 'Jessica', age: '21'}, 
{ name: 'Ben', age: '45'}, 
{ name: 'Samantha', age: '34'},
{ name: 'John', age: '90' },
{ name: 'Sandy', age: '67' },
];

Loop through the arr1. You get the names and the index. Based on index, get the ages from arr2 considering name and age array indexes are same

const arr1 = ['Jessica', 'Ben', 'Samantha', 'John', 'Sandy'];
const arr2 = ['21', '45', '34', '90', '67']; 

const result = arr1.map((name, index) => {
  return {
    'name': name,
    'age': arr2[index]
  }
})

console.log(result)

First, missing explanation. Second, please do not spoonfeed answers.

Add an explanation arr1.map((name, i) => ({name, age: arr2[i]})); and you can get upvotes.

Downvote does not mean incorrect. It means not required. Also vote is for missing explanation. Just putting code is not answer. Please explain what and why you have done
