Preview of our To-Do app

The best way to learn something is by doing. In this tutorial, we will be building a To-Do List app using pure JavaScript. If you are a beginner and tired of studying from boring theoretical tutorials then you are in a right place because here we will practically build this To-Do app from scratch. Don’t worry I have explained each and every step to develop our To-do app.

In this app, we will be able to add new tasks to be done, delete tasks, mark tasks after completion, we will have a drop-down menu to filter our tasks on basis…
