Modern JavaScript from the Beginning - Second Edition - Poll Project

The video tutorial demonstrates creating a simple voting application using HTML, JavaScript, and Bootstrap. It covers setting up a map to track votes for different frameworks, handling form submissions, counting votes, and displaying results. The tutorial also explains how to disable form inputs after submission to prevent multiple votes. Finally, it introduces the concept of custom data structures in JavaScript for future lessons.

What is the primary purpose of using Bootstrap in the voting application?

• To manage the application's data

• To handle form submissions

• To provide a responsive layout and styling

• To add custom JavaScript functionality

What data structure is used to keep track of votes in the application?

• Array

• Object

• Set

• Map

Which method is used to prevent the default form submission behavior?

• event.preventSubmission()

• event.stopImmediatePropagation()

• event.preventDefault()

• event.stopPropagation()

How does the application determine which option was selected in the form?

• By checking the form's action attribute

• By using a global variable

• By querying the DOM for the checked radio button

• By checking the value of a hidden input

What is the purpose of the 'displayResults' function in the application?

• To log the results to the console

• To update the map with new votes

• To reset the form inputs

• To display the voting results on the page

• d-grid

• flex-box

• d-flex

• flex-container

• They are cleared

• They are disabled

• They are highlighted

• They are hidden

Why might a real application need backend support for voting?

• To add more styling options

• To improve the application's performance

• To store votes persistently and prevent duplicate voting

• To handle more complex UI interactions

What is a limitation of the current voting application setup?

• It only works in modern browsers

• Votes are not stored persistently

• It cannot handle more than five options

• It requires a database connection

What is the next topic to be covered in the following video?

• Backend integration with Node.js

• JavaScript frameworks comparison

• Custom data structures in JavaScript

• Advanced CSS techniques
