   Show answer

   Answer: B. A statement that executes based on a condition

   A conditional statement allows execution of certain parts of the code based on whether a condition is true or false, making it a key concept in programming.

2. What will the following code print? if (true) { console.log('Yes'); } else { console.log('No'); }

   1. Yes
   2. No
   3. Nothing
   4. Error
   Show answer

   Answer: A. Yes

   Since the condition is 'true', the first block will execute, printing 'Yes' to the console.

3. What will be the output of the following code block? var a = 10; if (a == 10) { console.log('Ten'); } else { console.log('Not Ten'); }

   1. Ten
   2. Not Ten
   3. Error
   4. Nothing
   Show answer

   Answer: A. Ten

   The value of a is equal to 10, so the condition is true, and 'Ten' will be printed.

   1. The program will stop
   2. An error will occur
   3. The else block will execute if present

   1. With a semicolon ;
   2. With a period .
   3. With a comma ,
