Combine the values of two arrays into object

Let's break it down.

You have two arrays of equal length and you want to extract a value from each.

// Could also do array2.length since they're the same size for (var i = 0; i < array1.length; i++) { var val1 = array1[i]; var val2 = array2[i] } 

and you want to create an object using those two values

for (var i = 0; i < array1.length; i++) { var val1 = array1[i]; var val2 = array2[i] var obj = { meta: val1, value: val2 }; } 

Finally, you want to store each of those generated objects in an array

var result = []; for (var i = 0; i < array1.length; i++) { var val1 = array1[i]; var val2 = array2[i] var obj = { meta: val1, value: val2 }; result.push(obj); } 

And now you have your result!

You could rewrite this in a number of ways. For example:

var result = array1.map(function(val1, index) { return { meta: val1, value: array2[index] }; }); 

or if you're in an environment which supports it:

let result = array1.map((val1, index) => ( { meta: val1, value: array2[index] } )); 

Simple solution using Array.prototype.map() function:

var array1 = ["Bob", "John", "Dave"], array2 = [1, 2, 3], combined = array1.map(function(v, k, a){ return {meta: v, value: array2[k]}; }); console.log(combined);

You could use an object and iterate the keys and the values.

var array1 = ["Bob", "John", "Dave"], array2 = [1, 2, 3], object = { meta: array1, value: array2 }, result = Object.keys(object).reduce(function (r, k) { object[k].forEach(function (a, i) { r[i] = r[i] || {}; r[i][k] = a; }); return r; }, []); console.log(result);

.as-console-wrapper { max-height: 100% !important; top: 0; }

Assuming you're using Chrome, you could do:

const combined = array1.map((name,i) => ({meta: name, value: array2[i]}))
