How can you incorporate a line break into a template method?

Is there a way to create a line break in TypeScript? I tried searching for a solution here, but couldn't find one.

I currently have a method that displays 10 numbers, and I would like to insert a line break between each number.

I attempted using \n but it doesn't seem to work...

TS

export class AppComponent {

  constructor() {}

  public figure(): string {
    let txt = '';
    for (let i = 1; i < 11; i++) {
      txt = txt + i + ' \n ';
    }
    return txt;
  }
}

HTML

<h1>Exercise 9 </h1>
<p> {{ figure() }} </p>

Answer №1

To display the result in the browser's console, using \n is sufficient. However, if you want to showcase it in HTML, I recommend storing numbers in an array and utilizing Angular's built-in directive *ngFor to loop through the array:

public generateNumbers(): string {
  let nums = [];
  for (let i = 1; i < 11; i++) {
    nums.push(i);
  }
  return nums;
}

<div *ngFor="let num of generateNumbers()">
  {{num}}
</div>

Furthermore, it's advisable to store the result of generateNumbers in a variable to prevent unnecessary recalculations.

Answer №2

The problem at hand does not lie in the realm of typescript; rather, it stems from how you are displaying the output in HTML. In order for HTML to properly show a line break, you must include <br/>:

public figure(): string {
  let txt = '';
  for (let i = 1; i < 11; i++) {
    txt = txt + i + '<br/>';
  }
  return txt;
}
