FINAL Review!!!!!!!!!!!!!!!

Things you need to know:

variables
ifs
loops
array

mostly FUNCTIONS


function of 3 varieties

	the ones the do a job and die
	this that need inputs
	the ones that give outputs


Examples

function cat(){

	alert("*knocks stuff over*");
	alert("boop");
}



cat();

cat();





function dog(x,y){

	doggyx = x;
	doggyy = y;

	alert("Wooof");
}

dog(100, 450);



function parrotSqwak(){
	
	return "something clever only a human would say";

}



alert("Everyonelisten up : " + parrotSqwak() );



function gradeAvg(m1, m2, m3,m4){

	var res = 0;

	res = m1 +  m2 + m3 + m4;

	return res / 4;
}

//84.3

var myMark = gradeAvg(82, 72, 90, 56);

var betterMark = gradeAvg(82, 72, 90, 56) + 10;


function paint(){



	gradeAvg(82, 72, 90, 56)    // makes no sense, theres nothing to catch the returned value


	alert(m1); //m1 doesnt exist after the function runs



	for(var i=0; i < 10; i++){  //i  only exists for this loop


	}

	for(var i=0; i < 10; i++){// this 'i' is a different 'i' from that last loop, just has the same name


	}
}
