Filters in angular can do 3 different things
1. Format data
2. Sort data
3. Filter data

Filters can be used with a binding expression or a directive
To apply a filter use pipe (|) character
Syntax : {{ expression | filterName:parameter }}

Angular filters for formatting data

number Formats a number as text. Includes comma as thousands separator and the number of decimal places can be specified
currency Formats a number as a currency. $ is default. Custom currency and decimal places can be specified

Angular Date formats

Angular date format documentation

Script.js

 var app = angular

        .module("myModule", [])

        .controller("myController", function ($scope) {

            var employees = [

                {

                    name: "Ben", dateOfBirth: new Date("November 23, 1980"),

                    gender: "Male", salary: 55000.788

                },

                {

                    name: "Sara", dateOfBirth: new Date("May 05, 1970"),

                    gender: "Female", salary: 68000

                },

                {

                    name: "Mark", dateOfBirth: new Date("August 15, 1974"),

                    gender: "Male", salary: 57000

                },

                {

                    name: "Pam", dateOfBirth: new Date("October 27, 1979"),

                    gender: "Female", salary: 53000

                },

                {

                    name: "Todd", dateOfBirth: new Date("December 30, 1983"),

                    gender: "Male", salary: 60000

                }

            ];

            $scope.employees = employees;

            $scope.rowCount = 3;

        });
