###About
This is utilies for implementation quicksort algorithm, some quora said this is the best algoritm for sorting.

* .desc Sort data of array by descending order
* Can sort array of object based property of object

###How to use:

quicksort.desc(array, 'propertyObj', startIdx, endIdx)

###Example:
``
quicksort = require('quicksort.js');

quicksort.asc(array) // sort all array ascending
quicksort.desc(array) // sort all array descending

quicksort.asc(arrayOfObj, 'propertyObj') //sort array of object by property ascending
quicksort.desc(arrayOfObj, 'propertyObj') //sort array of object by property descending

quicksort.asc(array, undefined, 0,5) // sort all array ascending with range sort
quicksort.desc(array, undefined, 4,9) // sort all array descending with range sort
