Why is the function working without the content?

Question

Im wondering about the function which is empty and I dont call the function "myFunction();. But the function still works. Just wondering why. I thought, to run the function, it needs content in order to work. Obviously the function can be empty and does not need to be called with myFunction(); right?

Answer 1

You didn't need to put the statements

document.getElementById("my-div").innerHTML += " John";
document.getElementsByClassName("par")[0].innerHTML += " additional Input 1";
document.getElementsByClassName("par")[1].innerHTML += " additional Input 2";

inside a specific function like your function which is called
myFunction because each statement run by default when the complier arrive the line of code of it's
