What will be the console output when an error is thrown and caught in an immediately invoked function?

• A. 1 undefined 2
• B. undefined undefined undefined
• C. 1 1 2
• D. 1 undefined undefined

Answer: (A)

When an error is thrown and caught in an immediately invoked function, the console output can be understood by looking at the flow of code execution in relation to the error handling. If we consider a scenario where the immediately invoked function contains a structure like this: ```javascript (function() { console.log(1); try { // Code that throws an error throw new Error("An error occurred"); } catch (e) { console.log(2); } console.log(3); })(); ``` In this setup, the first line `console.log(1)` executes successfully and outputs `1`. 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

When an error is thrown and caught in an immediately invoked function, the console output can be understood by looking at the flow of code execution in relation to the error handling.

If we consider a scenario where the immediately invoked function contains a structure like this:

(function() {

console.log(1);

try {

// Code that throws an error

throw new Error("An error occurred");

} catch (e) {

console.log(2);

}

console.log(3);

})();

In this setup, the first line console.log(1) executes successfully and outputs 1. 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
