Can anyone explain all the pieces of the print function in this video? Particularly getElementById and innerHTML.

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

This seems like a fundamental part of javascript, but I am not yet understanding all of the pieces.

Hello Zach,

The function works as follows

//the function is declared with the name of print
function print(message) {
   // a variable is created and labeled 'outputDiv'
   // the variable is then pointing to an html element with the ID of output
   var outputDiv = document.getElementById("output");
   //the html element is then targeted and given text, using the given argument when the print function is called
   outputDiv.innerHTML = message;
}

//calling the print message and passing an argument
print("Hello, World!"); // "Hello, World" = message

I hope this helps.
