Day 3 of Training: To do list using Vanilla JavaScript

Today was the day 3rd of my training with Ryaz.
Task was focused on creating a simple to do list with Vanilla JavaScript in order to understand better the concept of Java DOM.

While working on the project I revised my previous concept regarding DOM. Also learnt some new features in this project.

I've added .addEventListeners to add task, to mark complete task(line-through) and to remove the task from the list(double-click).
