Object to Querystring - JavaScript, JS, JSON

javascript-object-to-querystring.js

function objectToQuerystring (obj) {
  return Object.keys.reduce(function (str, key, i) {
    var delimiter, val;
    delimiter = (i === 0) ? '?' : '&';
    key = encodeURIComponent(key);
    val = encodeURIComponent(obj[key]);
    return [str, delimiter, key, '=', val].join('');
  }, '');
}

i created a gist for to recursively encode and decode querystrings (encode = object to querystring, decode = querystring to object).
Feel free to copy/paste this in your own projects.

Thanks @darkylmnx (his answer) for your encode function. I added the corresponding decode function (both in typescript format).
I tested the code by creating an complex object, encoding it to a querystring and decoding it to an object, then i compared the input object with the decoded output object.

Great 🔥 💯

const objectToQuerystring = obj => new URLSearchParams(obj).toString();

lol

const objectToQuerystring = obj => new URLSearchParams(obj).toString();

lol

That doesn't work with objects that contain arrays or other objects.
