HTML CSS and JavaScript for Beginners - A Web Design Course - JavaScript Exercise #2: Function

The video tutorial guides viewers through creating a simple interactive UI with three buttons, each linked to a function that increments a variable. The tutorial covers setting up variables and functions, implementing logic to update and display variable values, and emphasizes the importance of efficient coding practices by reusing functions. The session concludes with a preview of more advanced function topics.

What is the initial value set for the three variables in the tutorial?

• 0

• None

• 1

• 10

What is the primary purpose of the first function implemented in the tutorial?

• To log a variable

• To reset a variable

• To increment a variable

• To decrement a variable

How does the instructor suggest handling multiple similar functions?

• By copying and pasting code

• By using a single function with parameters

• By using a loop

• By writing each function separately

What is the role of a trigger in the context of the tutorial?

• To delete a function

• To stop a function

• To pause a function

• To start a function

What happens when you click the buttons after implementing the message function?

• The page refreshes

• The variable values reset

• The variable values increment

• Nothing happens

What is the benefit of using functions according to the instructor?

• To make code harder to read

• To increase code length

• To avoid repeating code

• To slow down execution

What is the instructor's advice regarding writing the same line of code multiple times?

• It's recommended

• It's to be avoided

• It's necessary

• It's efficient
