Function:

Good way to think of a function is simply as a group of commands I give a name to, so I can easily run them (call them) again

More so, I can include some information when I call this function

We saw this last week

document.write(something)

Here, 'write' is the function

document is the object (we'll get there)

In write(something), 'something' is called an argument or a parameter

function myFunction(myparam){
	document.write(myparam);								
}

OR

myFunction = function(myparam){
	document.write(myparam);								
}

Camel-casing is not capitalizing the first word, but every word after that

myFunction("What I gots to say");

mystatement = "What I gots to say";
myFunction(mystatement);	
							

for(i=0; i < 5; i++){
myFunction('What I gots to say');
}

You can have multiple arguments

myFunction = function(paramone, paramtwo){
	document.write(paramone);
	document.write(paramtwo);							
}

myFunction = function(paramone, paramtwo){
	if(paramone == "my"){
		paramtwo = paramone + paramtwo;
	}
	else{
		paramtwo = paramtwo + paramone;
	}
	
	document.write(paramtwo);
}

Javascript uses the Document Object Model to work with HTML pages (and XML pages actually)

The Document Object Model is a way of thinking about the structure of an HTML page which allows us to navigate around and find specific pieces of the page or groups of pieces

Think of the folder structure on your computer, folders containing files or more folders, containing more folders or files, etc..

In the DOM, everything is a 'node'

In the DOM, each node can have children (which are nodes as well)

We can ask for the children of a node, or for the parent of a node

The text and whitespace within the tags are also nodes (Remember this one!)
