console.log(new greeting("Charlotte"));

Hello, Charlotte!

Explanation:

In the following program, Firstly we set a function "greeting" and pass an argument "name", inside the function.

  • Set a string type object "put" and initialize to "Hello" in it.
  • Set the if conditional statement to check the the argument "name" and concatenate the value of the "name" before "Hello".
  • Then, concatenate "!" after the "Hello" in name and print the object "put".

Finally, we call the function "greeting" through the pre-defined function "console.log()" by passing the sting inside the parameter.
