What will the output be after running this code: (() => { let x, y; try { throw new Error(); } catch (x) { (x = 1), (y = 2); console.log(x); } console.log(x); console.log(y); })();?

The output of the provided code comes down to understanding scoping and variable shadowing in JavaScript, especially within the context of try-catch blocks.

When the code is executed, the immediate function begins by declaring the variables x and y using the let keyword, which introduces block scope.

Then, the code enters a try block and deliberately throws an error, which is caught by the catch block. In the catch block, the parameter x is created, shadowing the outer x declared in the function scope. This means that within the catch block, the x that refers to the error object is different from the x declared outside of it.

Inside the catch, x is assigned the value 1, but this does not affect the outer x. On the other hand, y is assigned the value 2, which is applicable to the outer scope since it was declared outside of the catch block.

The following logs happen after the catch block:

1. console.log(x); will output 1 because within the scope of the catch, the shadowed x
