  • Last Updated : 01 Aug, 2022

An orderBy Filter in AngularJS is used to sort the given array to the specific order. The default order of sorting the string is in alphabetical order whereas the numbers are numerically sorted. By default, all the items are sorted in ascending order, if the ordering sequence is not specified.

Syntax:

{{ orderBy_expression | orderBy : expression : reverse : comparator }} 

Parameter Values:

  • expression: This parameter value can be used to determine the order while filtering the items. It can be the following types:
    • Function: This function is invoked by passing each item as an argument & the returned value will be utilized for sorting the corresponding items.
    • String: It can be an expression in AngularJS, that will be evaluated for every item & the output will be utilized to sort the item.
    • Array: It can be utilized when we need to determine more than 1 object property that helps to organize the sorting order. The array item can contain both the string & function.
  • reverse: It is an optional parameter that will be required to reverse the order of the array if its value is set to true.

Example 1: This example describes the orderBy Filter in Angular JS by specifying the order sequence for the array item by name.
