What is the purpose of the “main.ts” file in Angular?

The “main.ts” file in Angular is the entry point of the application and its main purpose is to bootstrap the root module of the application. This file is responsible for setting up the initial state of the application and launching the Angular framework. The bootstrapping process involves loading the root module, which is defined using the @NgModule decorator, and creating the main components of the application.

The “main.ts” file typically contains the following code to perform the bootstrapping:

import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
import { AppModule } from './app/app.module';

platformBrowserDynamic().bootstrapModule(AppModule)
  .catch(err => console.error(err));

In this code, the platformBrowserDynamic().bootstrapModule(AppModule) method is used to load the root module, AppModule, and start the application. The catch block is used to catch any errors that may occur during the bootstrapping process and display them in the console.
