The Modern JavaScript Bootcamp (2019) - Checkboxes

This video tutorial covers the use of checkboxes in HTML and JavaScript. It explains how to add labels to checkboxes for better user experience and how to handle checkbox events using JavaScript. The tutorial also demonstrates the application of checkboxes in a to-do app to filter completed tasks. A challenge is presented to implement checkbox filtering, followed by multiple solutions to the problem.

What is the primary purpose of using a label with a checkbox in HTML?

• To style the checkbox

• To provide a description for the checkbox

• To make the checkbox larger

• To change the checkbox color

Which event is most suitable for detecting changes in a checkbox state?

• click

• input

• change

• focus

In the to-do app challenge, what is the default state of the 'hide completed' filter?

• True

• False

• Null

• Undefined

What is the first step in implementing the 'hide completed' feature in the to-do app?

• Add a new checkbox

• Create a new filter

• Set up an event listener

• Modify the render function

How do you update the 'hide completed' filter when the checkbox state changes?

• By using the 'value' property

• By using the 'checked' property

• By using the 'innerHTML' property

• By using the 'textContent' property

What is the purpose of the 'render todos' function in the solution?

• To delete completed todos

• To add new todos

• To display todos based on filters

• To sort todos alphabetically

Which logical operator is used to combine multiple conditions in the filtering logic?

• AND

• OR

• NOT

• XOR

What is a benefit of using a one-liner solution for filtering todos?

• It is more secure

• It uses less memory

• It runs faster than other solutions

• It is easier to read and maintain

Why is it important to explore different solutions to a problem?

• To avoid using JavaScript

• To understand the problem better

• To impress others with your skills

• To find the fastest solution

What is the main takeaway from the section on exploring different solutions?

• There is only one correct way to solve a problem

• Multiple approaches can lead to the same result

• JavaScript is not suitable for complex problems

• Always use the longest solution possible
