AngularJS Filters

AngularJS Filters

Filters are extremely helpful tools for formatting data directly in the HTML view.

They transform data right before it renders, without altering the original model!


What is a Filter?

Filters can convert text to uppercase, format numbers as currency, or sort an array.

You apply a filter to an expression using the pipe character |.

AngularJS comes with numerous built-in filters, saving you from writing formatting functions.


Common Filters

Filters Example:

<div ng-app="myApp" ng-controller="myCtrl">
  <p>Name in Uppercase: {{ name | uppercase }}</p>
  <p>Price Formatting: {{ price | currency }}</p>
</div>

<script> var app = angular.module('myApp', []); app.controller('myCtrl', function($scope) { $scope.name = "John Doe"; $scope.price = 50; }); </script>


SEO and Best Practices

Rendering data clearly and cleanly enhances user experience drastically.

Properly formatted currency and readable text signal high-quality content to search engines.

Use filters to easily display dynamic data in a polished, professional manner.
