Modern Web Design with HTML5, CSS3, and JavaScript - Creating a Simple Game 'Switch Friends' with JavaScript - Coding Ch

The video tutorial explains how to use switch statements in JavaScript to check if a given name is in a list of friends. It starts by declaring a variable for a person's name and then uses a prompt to get user input. The switch statement checks the input against predefined cases for friends' names and outputs a message indicating whether the person is a friend. The tutorial also covers debugging the code by adding break statements to ensure correct functionality.

What is the primary purpose of using a switch statement in the context of this lesson?

• To create a new variable

• To identify if a person is a friend

• To sort a list of names

Which of the following is NOT a friend according to the switch cases discussed?

• Linda

• John

• Larry

• Jane

Why is it important to include breaks in switch cases?

• To prevent the code from running indefinitely

• To ensure the correct message is displayed

• To allow multiple cases to execute

• To improve code readability

What was the error in the code that caused it to not function as expected?

• An undefined function call

• A missing break statement

• An incorrect prompt message

• A missing variable declaration

How does the prompt enhance the functionality of the application?
