Learn HTTP in Angular

1. Let's use string interpolation 🤓

1. Create a joke variable in app.component.ts and assign this random joke: Ghosts are actually caused by Chuck Norris killing people faster than Death can process them.
2. Now go to app.component.html and replace its content with: <h1>{{joke}}</h1>. Now go and check the browser! 🚀

2. Let's use string interpolation and import HTTP 🔌

1. Now it's time to start using HTTP requests! Go to app.module.ts and import the HttpModule from import { HttpModule } from '@angular/http';.
2. Actually, to start using it we need to put it in the imports array: imports: [BrowserModule, HttpModule],
3. And the final step is to inject it in our component. Go to app.component.ts and create a constructor like this one: constructor(private http: Http) { }

3. Let's use string interpolation, import HTTP and fetch a information 🔥

1. So we are almost there! Last thing we want to do is create a channel (AKA Observable): http.get('https://api.icndb.com/jokes/random');
2. Second we will subscribe to it, so we can get a new joke http.get('https://api.icndb.com/jokes/random').subscribe();
3. Finally, we want to log the information in the console with: http.get('https://api.icndb.com/jokes/random').subscribe((response) => { console.log(response);});

4. Let's use string interpolation, import HTTP, fetch a information and show a Joke ⭐️

1. This is it, we only need to format the information correctly, replace console.log(response) with this.joke = response.json().value.joke;
