Program/Source Code:
The source code to demonstrate the Array.map() method is given below. The given program is compiled and executed successfully.
Output:
Explanation:
In the above program, we created an array arr with some elements. Then we used the map() method. The map() method is used to iterate over each element of the array, allowing you to perform actions on them. After that, we printed the result.
