Modern Web Design with HTML5, CSS3, and JavaScript - JavaScript Switch Statement - JavaScript Introduction

The video tutorial explains the use of the switch statement in JavaScript, demonstrating how it can be used to evaluate different cases based on a variable's value. It highlights the importance of the break statement to prevent fall-through and shows practical examples, including a fruit pricing scenario and a dynamic day-of-the-week selector. The tutorial concludes by emphasizing the readability and simplicity benefits of using switch statements over if-else constructs.

What is the primary purpose of the 'break' statement in a switch case?

• To terminate the switch statement entirely

• To skip the current case

• To prevent the execution of subsequent cases

• To restart the switch statement

In the example of determining the day of the week, what value corresponds to Friday?

• 6

• 0

• 3

• 5

What is the default case used for in a switch statement?

• To initialize variables

• To handle cases that match multiple values

• To execute code when no other case matches

• To terminate the switch statement

Why is it necessary to convert user input from a string to a number in the dynamic switch statement example?

• To make the input case-insensitive

• To match the input with numeric case values

• To ensure the input is not empty

• To prevent syntax errors

How can you make a switch statement dynamic according to the tutorial?

• By using a default case

• By adding more cases

• By using a prompt to get user input

• By using a loop to iterate through cases
