Created a video synchronization platform with javascript! I would love feedback!

I always wait too long to start adding tests and regret it; it's a hard discipline to adhere to. I guess that's why in true TDD you're supposed to write the test before you write the code :)

Sure, you'd need to choose a player type at some point, but then just pass that type around. In C# you'd just use an interface or abstract base class, all of your derived types would have the same methods as what you inherit from, and then you pass the interface or abstract around or use dependency injection. In JavaScript I guess you would just pass the object itself (compose it when you make the decision.) That way you wouldn't be having to figure out what type of player you have every time you call a method/perform an action.

class Player { constructor(url) { this.url = url; } }

class Youtube extends Player { play() { console.log("Youtube is playing:" + this.url); } }

class Vimeo extends Player { play() { console.log("Vimeo is playing." + this.url); } }

function somemethod(player) { player.play(); }

let myPlayer; let playerChoice = 'youtube';

if (playerChoice === 'youtube') myPlayer = new Youtube('someurl'); else myPlayer = new Vimeo('someurl');

somemethod(myPlayer);

Run this in node:

node player.js

Youtube is playing:someurl

I'll bite - why not?

they're annoying af
