AngularJS lowercase Filter

Last Updated : 05 Sep, 2022

AngularJS provides different filters to format the data. The lowercase Filter formats the given string to the lowercase. In order to transmit & render the data from a TypeScript code to an HTML template (view), the interpolation concept can be utilized. The lowercase filter is piped with an expression that is declared inside the interpolation syntax.

Syntax:

{{expression|lowercase}}

Example 1: This example describes the AngularJS lowercase Filter by converting the entered string to lowercase.
