[Feature Request]: Introduce taskset covering advanced topics for JavaScript

[annu12340]

Concepts like arrow function, spread operators, template literals, object destructuring, etc are missing in the js file. I would be great if you could include a separate file for these advanced concepts

We could think of introducing a next level covering up advanced topics 👍
