"Here's my code, please review it" is generally considered off-topic here. Code Review, by contrast, exists for precisely that purpose. — Charles Duffy 34 secs ago
In How to Answer, note the section "Answer Well-Asked Questions". As discussed in A Guide To Code Review For Stack Overflow Users, Stack Overflow permits only questions about specific, narrow problems with the shortest code necessary to reproduce a single preidentified issue; whereas our sister site Code Review permits only questions with complete, working code where general review is requested. This question is unambiguously in the latter category. — Charles Duffy 30 secs ago

Q: Very simple library system with JavaScript

Mauricio RobayoI am following the Odin Project and building the Library project. It is very simple, just render a list of Books and we can add and delete books from the list. However, I feel the code can be improved hugely, as it is getting too messy and I am not sure if I am using the class in the right way....

Your code is hard to follow. I am guessing that is due to how you indented the code. You can look here for some ideas. This question is hard to understand as-is. If my understanding of the question is correct, it's not a question for StackOverflow. This question my be better for CodeReview. I am not really sure. — Sedrick 33 secs ago

@Sedrick We have a dictionary file that we use to check the text in a TextArea after the misspelled words are found with enter the found !=true method where we want to go back in to the same dictionary and use the contains term to search for words that are correct. We then Stream or Iterate over the new "list" looking for correct spelling suggestions. Each method Streams and Iterator produced different results. YEP we did look at the Post you suggested.

@Duga Definitely, rolled back.
Dugo saves the day, again.
@SimonForsberg Well, it's very applicable at times. Some questions simply are not meaningfully reviewable without more context and a total waste of effort if they aren't fixed. It's too bad it's abused so often, but part of that may be due to the close reasons not being very intuitive.
We've tried to fix that, but you can't fix it all.

I've never quit before

@Gemtastic Just don't quit until you got a written contract in hand.
Signed contract.
 
Thanks!
Yeah I was talking to them about the start date as I am between assignments currently so I think my current employer will let me go asap as they don't earn any money on me atm
And they told me to wait before we signed too
That was a little embarrassing

The first time is always the weirdest. You get used to it, but it's never fun dealing with the paperwork.

@410_Gone Guy dropped the suit.
 
@410_Gone I'm not sure how much experience in either they want, I've never used either one.
 
I was just making the joke that a lot of these "recruiters" want N years of experience, when the language / ecosystem isn't even N years old.
 
@410_Gone Good for you, try not to get physical in the future.
@410_Gone been there done that
 
@pacmaninbw I probably will...but not because I want to, because I need to.
Gotta pay my lawyer about $500 for the consultation, and the "fine" for whooping him is $250, but the court hasn't ordered that yet.

@410_Gone Many times I wish I were in my 20's again, but then someone reminds me about the bad things about me in my 20's. I once pointed a gun a someone, then I put the gun down and picked the guy up by the throat. It really isn't worth it.
And yes his feet were dangling in the air.
 
How to pick up a guy:
1. Wrap your arms around his waist (should be easy enough if he's tall)
2. Hold on tight and lean back
3. Balance him on your hips.
4. His legs are now dangling and his frail masculinity injured.
Side effect; he might not hit on you the way you'd be wishing he did

That's quite a task you have there... Since you're already familiar with JavaScript I'd suggest you build on that because many questions don't seem like they'd need to be answered in a Java context, e.g. what tables should look like, how to prevent accidental deletions of products, authentication options (OAuth being one), persisting carts or working with a partner (like code reviews or pair programming). — Thomas 34 secs ago

@pacmaninbw Being in your twenties sucks. All the expectations, all the crap you have to figure out, all the mistakes to make and not the experience to properly deal with it half the time.
Although, honestly, 30's is just your 20's with more money.

Tik-Tok is a fictional character from the Oz books by American author L. Frank Baum. He has been termed "the prototype robot," and is widely considered to be the one of the first robots (preceded by Edward S. Ellis' Huge Hunter, or The Steam Man of the Prairies, in 1868) to appear in modern literature, though the term "Robot" was not used until the 1920s, in the play R.U.R. == Baum's character == Tik-Tok (sometimes spelled Tiktok) is a round-bodied mechanical man made of copper, that runs on clockwork springs which periodically need to be wound, like a wind-up toy or mechanical clock.

I'd say that nested ternary operations are not an acceptable style at least not in any code review I've ever attended. Just because you can do it doesn't make it an acceptable style. Style has to do with how the code looks and its readability and grokness. Readable and style are not necessarily two different things. — Richard Chambers 59 secs ago

Oh, not what I was expecting lmao
 
6:51 PM
Regarding the question, requests for tutorials are strictly off topic. You're better off muddling your way through with what you can find and then ask questions about why what you've tried doesn't work or asking at Code Review about how to make what you have better. This was the sort of problem Stack Overflow Documentation was supposed to help with. Real shame it didn't work out. — user4581301 19 secs ago
