Find the output ?

Code Breakdown:
let x = new Array(5);
Creates a new array named x with a length of 5. However, this technique initializes the array with empty slots (undefined).

x[3] = 1;
Assigns the value 1 to the element at index 3 of x. Since the array was initialized with empty slots, accessing x[3] before assignment creates an undefined value.

Attempts to use the map() method on the array x.

map() iterates over each element of the array, calling the provided callback function (each = { ... }) for each element.

Output:
Logged (is printed only once)
