Analyze the following code:

let x = 10function test() {
    let x = 20;
    console.log(x);
}

What will be displayed in the console as a result of its execution?

  • 20
  • Nothing will show up.
  • x
  • 10
Explanation & Hint:

Since the test function is never called in the code, the function is not executed, and therefore, nothing is printed to the console.
