1. Create an entry point HTML file where users will start
1. Load the Angular library at the top of the file
1. Make a root component for your application
1. Bootstrap Angular
You can edit and test out your apps by serving local files with a web server. Follow the steps in the <a href="../quickstart.html">quickstart</a> to get Typescript setup.
When you're serving local files, edit and save them and start a web server that serves files in that directory. If you have Python installed, you can run a basic HTTP server from the root of your code directory with:
The TypeScript setup includes System.js, a third-party open-source library that adds ES6 module loading functionality to browsers. This step isn't needed for the ES5 version.
A component annotation describes details about the component. An annotation can be identified by its at-sign (`@`).
The `@Component` annotation defines the HTML tag for the component by specifying the component's CSS selector.
The `@View` annotation defines the HTML that represents the component. The component you wrote uses an inline template, but you can also have an external template. To use an external template, specify a <code>templateUrl</code> property and give it the path to the HTML file.
The main difference between the ES5 and TypeScript versions is the loading of modules.
**TypeScript**<br/>
TypeScript supports ES6 module loading syntax. ES6 modules allow for modular loading of JavaScript code. Using ES6 modules you can cherry-pick only what you need for your app.
**Javascript**<br/>
In ES5 the script file creates an angular property on the window of the browser. This property contains every piece of Angular core, whether you need it or not.
