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"
