Hi,

Thank you for reaching out.

In a typical Angular app, you need both index.html and main.ts.

• index.html is the page the browser loads first. It just hosts the app and usually contains the <app-root></app-root> element.
• main.ts is where Angular starts running. It bootstraps the app and tells Angular what to load.

In simple terms, the browser loads index.html, and Angular kicks off from main.ts. and renders everything inside <app-root></app-root>.

So yes, for a standard Angular application, both files are required.

Hope this helps clarify things.
