CSV data loading as array of arrays; How to convert into object?

Question

I was wanting to see if there is a relatively simple method for doing this as I can use the following:

var arr = [ "Client", "ActType", "CallRepType"];
var arr2 = [ "ECF", "Meeting", "Call Report"]
var myobj = arr2.map(value => ({'Client': arr2[0], 'ActType': arr2[1], 'CallRepType': arr2[2]}));

But I get the same correct object 3 times in a row...I simply want a single object returned that looks like:

{Client: 'ECF', ActType: 'Meeting', CallRepType: 'Call Report'}

I know I can loop through both arrays but I was hoping to get a solution using map, reduce or taking advantage of spread in javascript...

• Randy Casburn: There is no such thing as a JSON object.
• Obsidian Age: ^ There's also no such thing as an ATM machine or a PIN number, but people still claim to use both ;)

Answer 1

A faster solution that uses Array.prototype.forEach():

var arr = [ "Client", "ActType", "CallRepType"];
var arr2 = [ "ECF", "Meeting", "Call Report"]
var result = {};
arr.forEach((el, i) => { result[el] = arr2[i]; });
console.log(result);

Array.prototype.forEach()`

• MattE: very nice! Works great

Answer 2

This a solution that uses Array.reduce() to create the object:

const arr = [ "Client", "ActType", "CallRepType"];
const arr2 = [ "ECF", "Meeting", "Call Report"]
const myobj = arr.reduce((r, key, i) => {
 r[key] = arr2[i];
 return r;
}, {});
console.log(myobj);

Answer 3

You can loop through the array and do it:

var arr = [ "Client", "ActType", "CallRepType"];
var arr2 = [ "ECF", "Meeting", "Call Report"];
var len = arr.length;
var myObj = {};
for (var i = 0; i < len; i++) {
 var myObject = {};
 myObj[arr[i]] = arr2[i]
 // myObj.push = myObject;
}
console.log(myObj);

• MattE: I know about looping through the arrays, I wanted to learn how to utilize built in methods to do it
• Pritam Banerjee: @MattE Ok, added one more example
• Stephen P: Neither method produces the OP's desired output, an object with the members {Client: 'ECF', ActType: 'Meeting', CallRepType: 'Call Report'} not an array of objects each with one member.
• Pritam Banerjee: @StephenP My bad. Removed it.
