Code sample comments

When we explain a piece of code in a post, we like to highlight the specific code lines with numbers / letters:

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

@Injectable()
export class RandomService {

    constructor() {}

    getRandomNumber(): number {
        return 4; // 🅰
    }

    getReferenceUrl(): string {
        return "https://xkcd.com/221/"; // 🅱
    }

}

🅰 Chosen by fair dice roll. Guaranteed to be random.
🅱 Inspiration for this brilliant algorithm, by xkcd.

You may choose among many different styles of letters and numbers.

Remarks:

We prefer 🅐 over Ⓐ as they are more visible.
⚠ Always have the unicode characters inside comments to allow copy pasting your code. Here, in Typescript, we use "//".
