HTML CSS and JavaScript for Beginners - A Web Design Course - Condition Statements JavaScript

The video tutorial covers the use of Boolean values in JavaScript, focusing on comparisons and conditional statements. It explains how to use if statements to apply logic, and introduces logical operators like AND and OR for combining conditions. The tutorial also covers the use of else and else if statements for handling multiple conditions, and demonstrates practical applications of these concepts with variables.

What type of value do comparison operations return?

• Array

• Boolean

• Number

• String

Which statement is used to execute a block of code only if a specified condition is true?

• while

• switch

• if

• for

• False

• True

• Undefined

• Error

Which logical operator will execute a block of code if at least one condition is true?

• AND

• OR

• NOT

• XOR

What is the purpose of an 'else' statement in conditional logic?

• To execute code when the 'if' condition is false

• To repeat a block of code

• To execute code when the 'if' condition is true

• To declare a variable

How does an 'else if' statement differ from an 'if' statement?

• It is used for loops

• It can only be used once

• It checks a new condition if the previous 'if' was false

• It executes code regardless of conditions

What will be the output if a condition in an 'else if' statement is true?

• The code block under 'else' is executed

• The code block under 'else if' is executed

• The code block under 'if' is executed

• No code block is executed
