Following are the program in the JavaScript Language.

//define function

function greeting(name)

{

//set string type object

put = "Hello"

//set the if conditional statement

if (name) {

//concatenate with the object

put += ", "+name;

}

//concatenate "!" with object

put += "!";

console.log(put);

}

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

Output:

Hello, Charlotte!

Step-by-step 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.
