How to sort an array of objects by multiple fields?

Question

From this original question, how would I apply a sort on multiple fields?

Using this slightly adapted structure, how would I sort city (ascending) & then price (

Answer 1

function sort(data, orderBy) {
        orderBy = Array.isArray(orderBy) ? orderBy : [orderBy];
        return data.sort((a, b) => {
            for (let i = 0, size = orderBy.length; i < size; i++) {
                const key = Object.keys(orderBy[i])[0],
                    o = orderBy[i][key],
                    valueA = a[key],
                    valueB = b[key];
                if (!(valueA || valueB)) {
                    console.error("the objects from the data passed does not have the key '" + key + "' passed on sort!");
                    return [];
                }
                if (+valueA === +valueA) {
                    return o.toLowerCase() === 'desc' ? valueB - valueA : valueA - valueB;
                } else {
                    if (valueA.localeCompare(valueB) > 0) {
                        return o.toLowerCase() === 'desc' ? -1 : 1;
                    } else if (valueA.localeCompare(valueB) < 0) {
                        return o.toLowerCase() === 'desc' ? 1 : -1;
                    }
                }
            }
        });
    }

Using :

sort(homes, [{city : 'asc'}, {price: 'desc'}])

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":"6",
     "city":"Dallas",
     "state":"TX",
     "zip":"75000",
     "price":"556699"},
    {"h_id":"5",
     "city":"New York",
     "state":"NY",
     "zip":"00010",
     "price":"962500"}
    ];
function sort(data, orderBy) {
            orderBy = Array.isArray(orderBy) ? orderBy : [orderBy];
            return data.sort((a, b) => {
                for (let i = 0, size = orderBy.length; i < size; i++) {
                    const key = Object.keys(orderBy[i])[0],
                        o = orderBy[i][key],
                        valueA = a[key],
                        valueB = b[key];
                    if (!(valueA || valueB)) {
                        console.error("the objects from the data passed does not have the key '" + key + "' passed on sort!");
                        return [];
                    }
                    if (+valueA === +valueA) {
                        return o.toLowerCase() === 'desc' ? valueB - valueA : valueA - valueB;
                    } else {
                        if (valueA.localeCompare(valueB) > 0) {
                            return o.toLowerCase() === 'desc' ? -1 : 1;
                        } else if (valueA.localeCompare(valueB) < 0) {
                            return o.toLowerCase() === 'desc' ? 1 : -1;
                        }
                    }
                }
            });
        }
console.log(sort(homes, [{city : 'asc'}, {price: 'desc'}]));
