Sorting an Array of Objects by Property Values

Here's a more flexible version, which allows you to create reusable sort functions, and sort by any field.

const sort_by = (field, reverse, primer) => {

  const key = primer ?
    function(x) {
      return primer(x[field])
    } :
    function(x) {
      return x[field]
    };

  reverse = !reverse ? 1 : -1;

  return function(a, b) {
    return a = key(a), b = key(b), reverse * ((a > b) - (b > a));
  }
}


//Now you can sort by any field at will...

const homes=[{h_id:"3",city:"Dallas",state:"TX",zip:"75201",price:"162500"},{h_id:"4",city:"Bevery Hills",state:"CA",zip:"90210",price:"319250"},{h_id:"5",city:"New York",state:"NY",zip:"00010",price:"962500"}];

// Sort by price high to low
console.log(homes.sort(sort_by('price', true, parseInt)));

// Sort by city, case-insensitive, A-Z
console.log(homes.sort(sort_by('city', false, (a) =>  a.toUpperCase()
)));

To sort it you need to create a comparator function taking two arguments. Then call the sort function with that comparator function as follows:

// a and b are object elements of your array
function mycomparator(a,b) {
  return parseInt(a.price, 10) - parseInt(b.price, 10);
}
homes.sort(mycomparator);

If you want to sort ascending switch the expressions on each side of the minus sign.

for string sorting in case some one needs it,

const dataArr = {

  "hello": [{
    "id": 114,
    "keyword": "zzzzzz",
    "region": "Sri Lanka",
    "supportGroup": "administrators",
    "category": "Category2"
  }, {
    "id": 115,
    "keyword": "aaaaa",
    "region": "Japan",
    "supportGroup": "developers",
    "category": "Category2"
  }]

};
const sortArray = dataArr['hello'];

console.log(sortArray.sort((a, b) => {
  if (a.region < b.region)
    return -1;
  if (a.region > b.region)
    return 1;
  return 0;
}));

If you have an ES6 compliant browser you can use:

• Arrow functions
• Number() function
• sort() function

The difference between ascending and descending sort order is the sign of the value returned by your compare function:

var ascending = homes.sort((a, b) => Number(a.price) - Number(b.price));
var descending = homes.sort((a, b) => Number(b.price) - Number(a.price));

Here's a working code snippet:

var homes = [{
  "h_id": "3",
  "city": "Dallas",
  "state": "TX",
  "zip": "75201",
  "price": "162500"
}, {
  "h_id": "4",
  "city": "Bevery Hills",
  "state": "CA",
  "zip": "90210",
  "price": "319250"
}, {
  "h_id": "5",
  "city": "New York",
  "state": "NY",
  "zip": "00010",
  "price": "962500"
}];

homes.sort((a, b) => Number(a.price) - Number(b.price));
console.log("ascending", homes);

homes.sort((a, b) => Number(b.price) - Number(a.price));
console.log("descending", homes);

You want to sort it in Javascript, right? What you want is the sort() function. In this case you need to write a comparator function and pass it to sort(), so something like this:

function comparator(a, b) {
    return parseInt(a["price"], 10) - parseInt(b["price"], 10);
}

var json = { "homes": [ /* your previous data */ ] };
console.log(json["homes"].sort(comparator));

Your comparator takes one of each of the nested hashes inside the array and decides which one is higher by checking the "price" field.

I recommend GitHub: Array sortBy - a best implementation of sortBy method which uses the Schwartzian transform

But for now we are going to try this approach Gist: sortBy-old.js.
Let's create a method to sort arrays being able to arrange objects by some property.

Creating the sorting function

var sortBy = (function () {
  var toString = Object.prototype.toString,
      // default parser function
      parse = function (x) { return x; },
      // gets the item to be sorted
      getItem = function (x) {
        var isObject = x != null && typeof x === "object";
        var isProp = isObject && this.prop in x;
        return this.parser(isProp ? x[this.prop] : x);
      };
      
  /**
   * Sorts an array of elements.
   *
   * @param  {Array} array: the collection to sort
   * @param  {Object} cfg: the configuration options
   * @property {String}   cfg.prop: property name (if it is an Array of objects)
   * @property {Boolean}  cfg.desc: determines whether the sort is descending
   * @property {Function} cfg.parser: function to parse the items to expected type
   * @return {Array}
   */
  return function sortby (array, cfg) {
    if (!(array instanceof Array && array.length)) return [];
    if (toString.call(cfg) !== "[object Object]") cfg = {};
    if (typeof cfg.parser !== "function") cfg.parser = parse;
    cfg.desc = !!cfg.desc ? -1 : 1;
    return array.sort(function (a, b) {
      a = getItem.call(cfg, a);
      b = getItem.call(cfg, b);
      return cfg.desc * (a < b ? -1 : +(a > b));
    });
  };
  
}());
