JavaScript:

/**
* Index of Multidimensional Array
* @param arr {!Array} - the input array
* @param keys {Object} - object of sorting order and coloum name
* @return {Array}
*/
function sortBy (arr, keys) {
return arr.sort(function sort (i1,i2, sKeys=keys) {
// Get order and key based on structure
const compareKey = (sKeys[0].key) ? sKeys[0].key : sKeys[0];
const order = sKeys[0].order || 'ASC'; // ASC || DESC
// Calculate compare value and modify based on order
let compareValue = i1[compareKey].toString().localeCompare(i2[compareKey].toString())
compareValue = (order.toUpperCase() === 'DESC') ? compareValue * -1 : compareValue
// See if the next key needs to be considered
const checkNextKey = compareValue === 0 && sKeys.length !== 1
// Return compare value
return (checkNextKey) ? sort(i1, i2, sKeys.slice(1)): compareValue;
})
}

How To Use?:

You can use it on associative (key/value) arrays as well as multidimensional arrays also. Just call the below code.
sortBy(your_array, [{key:"lastKeyName",order:'desc'}, {key:"secondKeyName",order:'desc'}, {key:"firstKeyName",order:'desc'}]);
You can write index number also instead of the key name. It will sort the last key first then will go step by step respectively.
