Frontend Web Development Bootcamp - Build a Twitter Clone - Conditional Statements

This video tutorial covers the use of conditional statements in JavaScript, including if-else and if-elseif statements. It explains how these statements are used for decision-making by evaluating conditions as true or false. The tutorial also introduces logical operators such as AND, OR, and NOT, demonstrating their application in checking multiple conditions simultaneously. Through examples, viewers learn how to implement these concepts in JavaScript code.

What is the primary purpose of conditional statements in JavaScript?

• To create loops

• To store data

• To make decisions based on conditions

• To perform arithmetic operations

In an if-else statement, what happens if the condition is false?

• The code inside the if block is executed

• The code inside the else block is executed

• The program terminates

• The condition is re-evaluated

How many else statements can you have in an if-else if structure?

• As many as needed

• One

• None

• Two

What will be the output if both conditions in an if-else if statement are true?

• Neither block of code is executed

• Only the first block of code is executed

• Both blocks of code are executed

• Only the second block of code is executed

Which logical operator returns true if both conditions are true?

• Logical AND

• Logical NOT

• Logical OR

• Logical XOR

What does the logical NOT operator do to a true condition?

• Returns undefined

• Returns true

• Returns null

• Returns false

When does the logical OR operator return false?

• When one condition is true

• When both conditions are false

• When one condition is false

• When both conditions are true
