Modern Web Design with HTML5, CSS3, and JavaScript - JavaScript Conditional (Ternary) Operator

The video tutorial explains the ternary operator in JavaScript, which is a conditional operator that takes three operands. It is used as a shortcut for the if statement, allowing for more concise code. The tutorial demonstrates how to use conditional statements to check if a value is greater than 100 and how to use the ternary operator to achieve the same result in a single line of code. A challenge is presented to determine if a number is odd or even using the ternary operator.

What is the primary purpose of the ternary operator in JavaScript?

• To define functions

• To serve as a conditional operator

• To execute loops

• To perform arithmetic operations

In a conditional statement, what message is displayed if the value is not greater than 100?

• The value is greater than 100

• The value is less than or equal to 100

• The value is exactly 100

• The value is undefined

How does the ternary operator improve code efficiency compared to traditional if statements?

• By allowing conditions to be written in a single line

• By using more lines of code

• By removing the need for variables

• By eliminating the need for conditions

What is the result of using the ternary operator if the condition is false?

• The true value is returned

• The false value is returned

• The condition is ignored

• An error is thrown

What is the remainder when an even number is divided by 2?

• 2

• 1

• 0

• Undefined

In the odd or even challenge, what does a remainder of 0 indicate?

• The number is odd

• The number is even

• The number is prime

• The number is negative

What is the initial value of the 'check' variable in the odd or even challenge?

• Odd

• Even

• Undefined

• Null
