try {

// Code that throws an error

throw new Error("An error occurred");

} catch (e) {

console.log(2);

}

console.log(3);

})();

Then, an error is thrown, which is caught by the catch block, leading to the execution of console.log(2), resulting in 2. After the catch block, if there’s nothing more to execute because of the error, the immediately invoked function does not proceed to the next console.log(3) due to control flow being interrupted.

In the correct choice, the output of the console in this case would be 1 followed by undefined because if no additional logging occurs after the catch, that results in undefined being logged as part of how the Java
