// Both ways to create functions use the function keyword, so the difference between them aren't immediately apparent.

//******************
// Declarations
//******************

// Variable declarations and functions declarations operate similiarly. They start with a keywords (var or function), followed by an identifier.
// Function declarations add lists of arguments in parentheses followed by blocks in curly braces.

function functionName(arg1, arg2, argN) {

//***********************************
// TextContent vs innerText
//***********************************

// Innertext returns with a line breaks in it because it behaves like you'd copy and pasted the element, and becasue div is block level it put "World" on a new line. innerText is styles dependant, so will therefore have to check the style sheet 
var div = document.createElement('div');
div.style.background = 'url(img.png)';
div.innerHTML = "hello <div>world</div>";
document.body.appendChild(div);

//Alternative to setInterval
 
//Set interval will run the function doStuff() every 100ms regardless if doStuff has finished.
setInterval(function(){
doStuff();
},100);
 
 
//Alternatively you can use argements.callee after doStuff(); which will is wrapped in a self invoking anyonomous self invoking function
