### Learning Objectives

- [ ] Develop a web app according to a specification
- [ ] Update the DOM in response to input from the user

### Why are we doing this?

These challenges are designed to develop your problem-solving skills.

In this exercise you will build a to-do list which meets the following criteria:

#### Acceptance criteria

- [ ] Given a todo list web application
When the page loads
Then the populateTodoList() function should create todo list items for each hardcoded todo
When a todo list item is created
Then it should contain: ☑ 🗑 todo text
When the checkbox icon is clicked
Then the todo text should have strikethrough
And the checkbox should be ticked ✅ 🗑 ~todo text~

- [ ] Given a todo list item on the page
When the trash icon is clicked
Then the todo list item should be deleted

- [ ] Given a button to add new todos
When the button is clicked
Then a new todo should be added to the list with the checkbox and trash icons

- [ ] Given a button to mass delete completed todos
When the button is clicked
Then any todos that have been checked off should be deleted

- [ ] Given the ability to set a deadline when creating a todo
When a deadline is set
Then the deadline should be displayed next to the todo text
