Create a function greeting(name) that accepts a name argument and returns a personalized greeting if a name is present (must be done in javascript)

example:

input: greeting("charlotte");

output: "hello, charlotte! ";

input: greeting();

output: "hello! ";

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!

Explanation:

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

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