1. In a 'for' loop, what does the initialization statement typically do?

• Defines the loop condition
• Executes the loop body
• Initializes the loop variable
• Indicates the end of the loop

2. How is a 'while' loop different from a 'do-while' loop?

• 'while' checks the condition before the loop body, 'do-while' checks after
• 'while' is used for finite loops, 'do-while' for infinite loops
• 'do-while' does not exist in JavaScript
• 'while' and 'do-while' are interchangeable

3. What is the result of the following code: 'for (let i = 0; i < 5; i++) { console.log(i); }'

• 0, 1, 2, 3, 4
• 1, 2, 3, 4, 5
• 5, 4, 3, 2, 1
• 0, 1, 2, 3, 4, 5

4. What is the purpose of the 'continue' statement in a loop?

• Jumps to the next iteration of the loop
• Exits the loop prematurely
• Skips the current iteration
• Creates an infinite loop

5. Which loop is suitable when the number of iterations is known beforehand?

• for
• while
• do-while
• if

6. How do you create an infinite loop intentionally in JavaScript?

• Using 'for' loop with no condition
• Using 'while' loop with no condition
• It is not possible to create an infinite loop intentionally
• By using the 'break' statement

7. In a 'for' loop, where should the loop variable be declared?

• Outside the loop
• Inside the loop body
• It is not necessary to declare the loop variable
• Before the initialization statement

8. What does the 'break' statement do in the context of loops?

• Jumps to the next iteration of the loop
• Exits the loop prematurely
• Creates an infinite loop
• Skips the current iteration

9. Which loop is best suited when you want the loop body to execute at least once?

• for
• while
• do-while
• if

10. What is the primary purpose of using loops in JavaScript?

• To declare variables
• To control the program flow based on conditions
• To perform repetitive tasks efficiently
• To handle errors
