how to use the javascript console

JavaScript
/*

shortcuts:

command K = clears the console
command shift M = toggle device toolbar
command shift C = select something on the page

you can also log in a variable you may have coded:

x;
[value of x at that moment]

if you're animating something:
noLoop();
[stops the animation]

loop();
[continues the animation]

you can also code somewhat intricate text:

for (var i = 0; i > 10; i++) {
	console.log([variable or anything]);
}
  
some functions are also available to use:

function mousePressed() {
	console.log([anything]);
}

function keyPressed() {
	noLoop(); [or anything else]
}
