It can be occasionally useful.

Well, I never use it because of inspect, but I always thought it was cool when I was first learning it. 

I have used the contenteditable attribute though to create custom facebook like inputs :-) its cool.. allows u to do things that a normal textbox or input cant [ rich input    ]

Inspect element you can color, bold, add images, etc.

*facepalm*

Do you expect the user to be able to use inspector ? seriously ?

it makes sense using inspector

In JS, you can't equality-test arrays (something I truly hate).

console.log(grid[0][0]==0 && grid[0][1]==0 && grid[0][2]==0);

Wait whaaaaaaaaaaa ?

&& is boolean and.
So raining && cold means "raining and cold".
Or one && two && three means "one and two and three".
Or equals1 && equals2 && equals3... or grid[0][0]==0 && grid[0][1]==0 && grid[0][2]==0

Say

Are layers like Sprites?

(Just curious)

i have a question, how do you check if a string is valid hex code

function isValidHexCode(hexCode){
    if(hexCode.length!==6){ //I know you can get three-character hex codes that are valid but I'll do that later
        return FALSE;
    }
    var i;
    var allowed=new Array("0", "1", "2", "3", "4", "5", "6", "7", "8", "9", "a", "b", "c", "d", "e", "f");
    for(i=0; i<6; i++){ //Check all characters separately, so check the first character, then the second, etc.
        if(!hexCode.charAt(i).toLowerCase() in allowed){
            return FALSE;
        }
    }
    return TRUE;
}

i tried that but it's not working

i tested it with

if(isValidHexCode("aaaaaa")){
    alert("Yes");
}else{
    alert("No");
}

if(isValidHexCode("zzzzzz")){
    alert("Yes");
}else{
    alert("No");
}

but it just wasn't alerting anything
i think it's the "in" part on line 8, i've never heard about the "in" operator before

i've probably made dozens of syntax errors i don't really know js too well

Where

from what I saw in w3schools (I'm no javascript expert, I still use it), there is no "in" operator. The only time that 'in' is used as something inside a parameter (besides for user defined functions), is the for (x in object).
What you should do instead is using IndexOf().
Although it is used for finding the item #, you can replicate the

<[list v] contains [thing v]>

console.log(!arrayObject.indexOf('thing')==-1);

that should do what you want in the code above, if it's still wrong, then I don't know.

Edit: didn't scroll through bobbybee's code. It's shown in there too.
Sorry bobby.

oh okay

thanks

Java scripts great!  I am making a chatbot.  Also an RPGs, platformer, matrices calculator, and a few others.  It's super cool.  Also I use processing.js.  I am making a mod where it converts scratch into JavaScript.  Overall, great language!  My mom hates bit when I commentate in JavaScript.

Do you need an "else" statement?

you don't need one, since the only way it will get to the part where it returns TRUE is if the hex code is valid
if it's not valid, it will never reach it to that point

also it's interesting that you have to return 0 or 1 instead of FALSE and TRUE
i guess i should research these things before i assume it's the same as in php

you don't.
it works fine when you do

return true;

I never seemed to be able to do this, so can someone help me: I don't know how to turn a hex code into RGB,be able to edit the values, and then turn it back into hex.
Basically replicating the

change pen color by (number)

You'd just have to convert the hex values of the RGB color to decimal - this gives you an integer between 0 (0x00) and 255 (0xFF) for each color.

edit: dhrnkljsgrnjklsgj ninja'd. I was going to explain how to convert from hex to decimal, but it wasn't clear :c Have a link instead.
