no return for the print function?

just wondering why there is no "return message" in the print function.....

1 Answer

Lets break down the print function used and maybe we can find out why:

function print(message) {
  var outputDiv = document.getElementById('output');
  outputDiv.innerHTML = message;

outputDiv.innerHTML = message;

is the key to your question. .innerHTML sets/returns the HTML value/content of the element. So the print function does return a value but by using innerHTML. This will return the HTML value of the argument that is set by the parameter message in our function. I hope this helps. if you want to learn more about innerHTML take a read.


I hope this helps.
