An issue occurred when attempting to integrate Angular

Currently, I am in the process of learning AngularJS. To practice, I attempted a simple code snippet in an HTML file:

  <!DOCTYPE html>
    <html lang="en" ng-app="">
        <head>
            <meta charset="utf-8">
            <meta http-equiv="X-UA-Compatible" content="IE=edge">
            <meta name="viewport" content="width=device-width, initial-scale=1">
            <title>Title Page</title>

            <link rel="stylesheet" href="bootstrap.min.css" >
        </head>
        <body>
            <input type="text" ng-model="name">
            <div>hello{(name)}</div>
            <!-- jQuery -->
            <script src="https://cdnjs.com/libraries/angular.js/"></script>
    </body>
</html>

However, when I checked this code on my web browser, it did not work as expected and displayed an error message in the console:

Uncaught ReferenceError: System is not defined on line 2

I'm puzzled by this error. Can someone shed some light on why I'm encountering this issue?

When including content from

https://cdnjs.com/libraries/angular.js/

, it's important to select the specific script you want to include. For example:

<script src="https://cdnjs.cloudflare.com/ajax/libs/angular.js/1.5.8/angular.min.js"></script>

Remember, it should be written as {{name}} with two curly braces, not {(name)}

  <!DOCTYPE html>
    <html lang="en" ng-app="">
        <head>
            <meta charset="utf-8">
            <meta http-equiv="X-UA-Compatible" content="IE=edge">
            <meta name="viewport" content="width=device-width, initial-scale=1">
            <title>Title Page</title>
            
        </head>
        <body>
            <input type="text" ng-model="name">
            <div>hello {{name}}</div>

This reference is directing you to the AngularJS CDN site:

<script src="https://cdnjs.com/libraries/angular.js/"></script>

You will need to choose a specific version. For instance, the Minified AngularJS version 1.5.8 is as follows:

<script src="//cdnjs.cloudflare.com/ajax/libs/angular.js/1.5.8/angular.min.js"></script>

Please remember to omit the https.

Additionally, be sure to utilize {{ name }} when displaying a variable in AngularJS rather than {(name)}.

It's important to address a couple of key points in this situation.

The import issue. Other responses have already pointed out why it's not functioning correctly. It needs to be fixed.
Working with Angular. Angular operates using applications and controllers (for the basic level). To make it work, you must create a file to house your controller. For instance, you can name the file myapp.js and include it in your webpage like so:

<script src="path/to/myapp.js"></script>

After setting up your application (

var myApp = angular.module('myApp',[]);

) and controller (refer to the AngularJS documentation for guidance), you can initialize your data with the scope:

$scope.name = 'John';

Add your application to your HTML page:

<html ng-app="myApp">

You will witness the magic unfold as intended:

hello {{ name }} // and not {( name )}

Your browser should display:

hello John
