if you don't believe that adding more structure to the absolute maniacal catastrophe that is sql is a good thing then i'm going to start to have doubts about your authenticity as a human being
it was written to be a language that anybody could read or write as well as english, which just like every other time that's been tried, results in a language that's exactly as anal about grammar as C or Python except now it's impossible to remember what that structure is because adding anything to the language to make that easier is forbidden
when you write a language where its designers were so keen for it to remain human readable that they made deleting all rows in a table the default action, i don't think "well structured" can be used to describe it
Because you never learned SQL properly, from the sound of it.
You might be right, though, to be fair, I also keep forgetting syntax of stuff when I don’t use it very often (read SQL (._.`))
Also, ORMa produce trash queries and are never expressive enough.
I meant to say that I would like the raw SQL syntax to be more similar to other programming languages to avoid needing to switch between thinking about different flows of logic
No. The arrow function in where eliminates any possibility of using indexes. And how do you propose to deal with logical expressions without resorting to shit like .orWhereNot() and callback hell? And, most importantly, what about joins?
SQL is incredibly structured. It’s also a very good language, and developers need to stop piling on junk on top of it and producing terrible queries. Learn the damn language. It’s not that hard
That would be weird if a string containing a space wasn't equal to 0 " " == 0, but that's not the case in JS. If you think that "" and " " being equal to 0 is weird then I agree, but since they are, you should expect "t" and "n" to equal 0 too.
The == operator in JS will try to cast the things being compared and do all kinds of ‘smart’ assumptions about what equality means. This is why everyone uses === instead…
If " " wasn't equal to 0, it wouldn't make sense, but since a string containing a space equals 0, you'd expect the same to apply to a string containing a tab or a newline. (or at least I'd expect that)
I admit I have never dabbled in javascript, despite being a proficient programmer. I now dread to ask... would any string that contains only whitespace == 0? " \t\n \t " for example?
Yes, it would. Just like a string of spaces " " == 0, but it isn't that bad; === is Javascript's version of == in other languages, and, thus, you should be using it if you don't want that wonkiness.
== is just for convenience, like when you want to make sure that the user didn't leave the form empty and the button shouldn't be greyed out, and other UI stuff. Without these kinds of features JS wouldn't be used in so many toolkits.
Ok, I always mistakenly assumed === was the identity operator in JS, too. TIL, thanks! As much as we like to poke fun at JS, every time I’m taught the rationale behind some aspect of it, I find it redeeming and even a little endearing.
The explanation given to you makes it sound like == was deliberately designed to be a more convenient version of ===, but what actually happened was that == used to be the only equality operator in JavaScript, which meant that if you didn’t want it’s auto-coercing behavior then you needed to go out of your way to add additional type checks yourself. Because this was obviously a tremendously inconvenient state of affairs, the === operator was introduced later so that you could test for equality without having to worry about JavaScript doing something clever underneath the hood that you weren’t expecting.
The explanation given to you makes it sound like == was deliberately designed to be a more convenient version of ===
I mean technically == was deliberately designed to be a more convenient version of other languages’ == operator… Just specifically more convenient for light UI stuff since that was all JavaScript was supposed to be used for at the time (or all they thought it would be used for).
But give programmers a way to write and execute a small script and someone will eventually use that to try and write an emulator that emulates the computer it’s running on, so the web evolved into more complicated applications, and then that convenience turned out to be wildly inconvenient, not to mention horribly unexpected for programmers coming from other languages, so then they added the triple equality to match other languages.
Yeah, it’s true. I knew all the other ones, had to put that one in the dev tools console to believe it. I was just happy to know === continues to be sane in that comparison.
You have to remember that the underlying principle of JavaScript seemed to be “never throw an error”, even if what it’s being told to do is weapons grade bollocks.
I’d like you to think for a moment about CTEs, the HAVING clause, window functions and every other funky and useful thing you can do in SQL … Now just think, do you think that this syntax supports all those correctly?
I was disgusted by the XML at first, but it’s a readable query returning a sane JSON object.
Meanwhile, I’m mantaining Java code where the SQL is a perfectly square wall of text, and some insane mofo decided the way to read the resulting list of Object[] 🤮 is getting each column by index… so I’d switch to SQXMLL in a heartbeat.
