Turn properties of object into a comma-separated list?

Question

I have an object like this:

var person = {
  name: \"John\",
  surname: \"Smith\",
  phone: \"253 689 4555\"
}

I want:

Answer 1

Write a function like this:

function toCSV(obj, separator) {
    var arr = [];

    for (var key in obj) {
        if (obj.hasOwnProperty(key)) {
            arr.push(obj[key]);
        }
    }

    return arr.join(separator || ",");
}

And then you can call it like:

toCSV(person, "|"); // returns "John|Smith|253 689 4555"

or

toCSV(person); // returns "John,Smith,253 689 4555"

Answer 2

You can use this one-liner in modern browsers

Object.keys(person).map(function(k){return person[k]}).join(",");

Answer 3

This code will be useful when you want to extract some property values from an array of objects as comma separated string.

    var arrayObjects = [
  {
    property1: "A",
    property2: "1"
  },
  {
    property1: "B",
    property2: "2"
  },
  {
    property1: "C",
    property2: "3"
  }
];

Array.prototype.map.call(arrayObjects, function(item) { return item.property1; }).join(",");

Output - "A,B,C"

Answer 4

Another way is to use lodash function _.toString()

console.log( _.toString( Object.values( person ) ) );
==> John,Smith,253 689 4555
