For my most recent Flatiron School project, I wanted to be able to programmatically change the background color of one of the elements on the page,...

Nice work! I love seeing the thought processes behind figuring out how to make code better. It's like watching someone piece together a mystery in front of you.
I'm sure you know this as well, but for anyone who doesn't, if you prefix a number with
0xyou can use hex values in your code. (There's also0bfor binary and0ofor octal).Something else to note is that when using Math.floor1 since
Math.randomgenerates a random number between 0 and 1, but never exactly 1, you have to add 1 to your maximum or else it will never generate that value. So in this case, you should go up to16or you'll never get the valuef:1 I didn't read the article well enough and assumed
Math.floorwas being usedThanks, Khauri! I actually didn't know about the
0xthing. That's super cool! And ++ to the Math.floor() point. It's one of those things I always forget. I used Math.round() in its place but do know that that's not the best solution.Yeah someone else pointed this out to me. Math.floor vs Math.round is one of those things I always forget. Also, excellent work on the alt method! Just as a note, with that solution, it is possible you will get hex codes that are less than 6 digits in length, which won't work as color codes. You'll still need a way to check for the length of the code.
Just wanted to say I am proud of you for writing this post!
It is great and I must go do something similar now 😂 maybe with cats 🤔
I demand colorful cats!
O M G !!! How do I do colorful cats? Idk but I must find out!
I have no idea but I believe in your ability to figure it out haha
Thank you for your trust! 🌈😽😼
Just to clarify, in the article, the intention is to generate individual digits and convert them to hex one at a time until you have a string of 6 hexadecimal digits. If you just generate any decimal number between 0 and 16777215 and then convert that number to hexadecimal, it will sometimes output hexadecimal numbers shorter than 6 digits (i tested and got a few 4 and 5 digit results) which cannot be used as a hex color code and will cause the function to break if used to assign a code to an element on the page. You still need a way to check for length of 6 on your output. That said, your code does work a lot of the time. But sometimes it doesn't. For me, it broke about 1/20 times when I tested it.
You could also scale your random by the max value #ffffff and you wouldn't need a loop.
Someone else pointed this out, and it does work quite often, but you do still need to check for a length of 6 on your output for it to be a valid hex color code. Testing that code, it does occasionally output numbers of 4 or 5 digits in length which will break the intended functionality.
I believe that there is a function to pad the left side of the string with zeroes up to a given length (or you could do it yourself)
so fun
I know, right!? I want to sit and click that lil square on codepen forever haha
Your code is shorter but harder to understand.
Very Nice!
But, I could see the function is excluding the value
fevery time. Do you have a fix for that?
