After successful installation of angular web development framework and site creation, go to your drive where you have installed it. For Example, C: or D: or any other drive. Follow this path: Drive>YourProjectName > src > app folder. You will see three files. They are: 1. App.component.ts 2. App.module.ts 3. App.component.html
Go to Drive>YourProjectName > src folder. You will see 2 more files, i.e., 1. Main.ts 2. Index.html
Among these 5 important files, app.component.ts is used to design a webpage.

C:/YourProjectName> ng serve –o This command is used to run an angular application. It will convert .ts extension file to .js file and gives output to index.html
