![Build in Filters
A filter formats the value of an expression for display to the user. They can be used in view templates, controllers or
services and it is easy to define your own filter.
In Other word you can say, a filter provides a way to format the data we display to the user. Angular gives us
Several built-in filters as well as an easy way to create our own.
We invoke filters in our HTML with the | (pipe) character inside the template binding characters {{
}}.
Example 1
external.js
//defining module
var app = angular.module('IG', [])
app.controller('FirstController', ['$scope', function ($scope) {
$scope.customers = [
{
name: 'David',
street: '1234 Anywhere St.'
},
{
name: 'Tina',
street: '1800 Crest St.'
},
{
name: 'Brajesh',
street: 'Noida'
},
{
name: 'Michelle',
street: '890 Main St.'

Built in filters
Filters format data for display to users. Built-in filters include filter to search/filter data and orderBy to sort. Custom filters can be created to format data as needed, like converting large numbers to abbreviations. Filters are invoked with a pipe (|) in bindings like {{expression | filter}}. Examples demonstrate using built-in and custom filters.
