Angular beginner's webpage experiences technical difficulties

My Angular (or TypeScript) code is compiling and running successfully, but I'm facing an issue when trying to load the page in Firefox as it crashes. The problematic code resides in

app.component.html

<h1>Angular</h1>
<dd-button></dd-button>

app.module.ts

import { DdButtonComponent } from './ddButton.component';
import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';

import { AppComponent } from './app.component';

@NgModule({
  declarations: [
    AppComponent,
    DdButtonComponent
  ],
  imports: [
    BrowserModule
  ],
  providers: [],
  bootstrap: [AppComponent]
})
export class AppModule { }

ddButton.component.ts

import { Component } from '@angular/core';

@Component({
  selector: 'dd-button',
  template: "<dd-button>Text</dd-button>"
})
export class DdButtonComponent {
}

app.component.ts

import { Component } from '@angular/core';

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
})
export class AppComponent {
  title = 'Explaining Modernity';
}

I apologize for my lack of expertise with this issue, but without any error indications, it is challenging to identify the root cause. To elaborate on the crash further, upon attempting to open the page using localhost:4200, the browser hangs for a moment before displaying the "page crashed" message in Firefox.

The dd-button component is making a self-referencing template error:

selector: 'dd-button',
template: '<dd-button>Text</dd-button>',

This results in each instance of dd-button attempting to render another dd-button, causing an infinite loop that eventually crashes the browser due to stack overflow.

You probably meant to use

<button>Text</button>
instead.
