Why would you use anything other than Math.max?
Some of us have trust issues. Or worked with Java.
Which, now that I think about it, comes to the same thing.
Why would you use anything other than Math.max?
I mean, I might be being paid by the hour or my performance measured by lines of code…
Thief way is actually the best among all of these imo, in terms of readability and efficiency.
Not using thief is professional incompetence unless you’re doing something deeply cursed
Fr. People like to reimplement wheels tho
Sometimes you need to minimize function calls in a tight loop, but otherwise yeah
Why would you be using JS in this scenario?
Node.js, electron 🤷♂️
Something has gone horribly wrong if you’re trying to do such optimisations when you’ve already chosen JavaScript…let alone Electron.
And yet it happens, just look at the molasses that is Teams
Thankfully the only interaction I have with teams is when a supplier arranges the call. Once every two weeks. It grosses me out every time…and that’s the Web app.
Do you really think they have done such optimisation efforts as minimising function calls? I can’t imagine it’s required for what is actually a fairly simple frontend app. The complexity is the enabling stack on the backend.
Good answer.
Even if it made me throw up in my mouth a little. /s
Edit: Not the concept of Electron, itself - but being asked to write highly performant code in Electron.
I was under the impression that modern compilers just inline something like that, and even in older languages (like C) use trickeries are used to inline it (typically MAX is a macro rather than a real function, so its always inlined)
Ultimatelly it depends not just on what you’re doing but also the language and compiler you’re using.
If you’re optimizing that hard you should probably sort the data first anyway, but yeah, sometimes it’s absolutely called for. Not that I’ve actually needed that in my professional career, but then again I’ve never worked close enough to metal for it to actually matter.
That said, all of these are implemented as functions, so they’re already costing the function call anyway…
Sometimes, but practically never. Just be a thief.
They’re setting a variable to a function. Just use the original function. All thief does is obfuscate for literally no gain except character count.
I presumed it to be a standin for just directly using Math.max, since there’s no nice way to show that in a valid code snippet
well it’s called Thief. They’re stealing the function and making it look like they wrote it. hence
max1.Yeah, that’s my reading as well.
Sounds good to me
TDD
const max12 = (x, y) => { if (x === 1 && y === 2) { return 2; } else if (x === 7 && y === 4) { return 7; } else { return x; } };Thief. Writing code is for chumps, and the more code you right, the more of a chump you are.
why say many word when few do trick
Why 🗣️📈 word when 😃👍

So you’re the one in there wronging up my code?
It’s too late now to wright my wrongh
¯\_(ツ)_/¯
Where’s the Julia programmer that hits every one of these with @benchmark and then works for six hours to shave three nanoseconds off of the fastest one?
(Example: https://discourse.julialang.org/t/faster-bernoulli-sampling/35209)
404 or walled
works here
Mathematician 2 kinda blew my mind, kinda obvious, just can’t believe I was never taught or thought about it.
Yeah, that was my favorite one
Lost me when it used Math.abs after calling math.max a their
Math.Sqrt((x-y) * (x-y))(I’ve actually seen someone use this)
I’ve been staring at it for 10 minutes and I’m still not convinced it works.
Simple, really. Abs(x-y) is the difference between the two numbers, absolute, so positive value. So, adding abs(x-y) to the smaller of the two numbers turns it into the bigger number. Plus the bigger number, now you have 2 times the bigger number
Thief no doubt
Thief gang. Why stand on shoulders of giants if you’re not using it to your advantage?
Procrastinator + troll.
return xBit hacker 2 is really fascinating. It uses a bit mask of all 1s (-1) or all 0s (0) and takes advantage of the fact that y ^ (x ^ y) = x and y ^ 0 = y
wtf kind of cursed programming language is this? JS? it’s so ugly, in no universe should a function look like that
but obviously as a rust enjoyer i have to do it like
fn max ⟨T: PartialOrd + Copy⟩(nums: ⁊[T]) -> Option⟨T⟩ { let mut greatest: ⁊T = ⁊nums[0]; match nums.len() { 0 => None, 1 => Some(*greatest), _ => { for num in nums { if num > greatest { greatest = num; } } Some(*greatest) } } }edit: lemmy formatting REALLY hates references and generics it seems… time to go back to medieval times
Ah yes, rust. The language that somehow manages to manages to as verbose as possible, with as much jargonized shorthand that a computer could handle.
Exactly, I don’t understand why languages have decided that every keyword needs to be as randomly minified as possible.
fn,def,rune(ok that’s not minified, just a dumb name),fmt,std. Many of these things aren’t new, but programmers recognize descriptive variable names are important, the same should be true for keywords.
Wow that’s a very exhausting language. I dropped your code into an online rust to asm converter and it actually wasn’t more! I did try to post it for fun but lemmy kept messing up the code block. Oh well, wasn’t that amusing anyway!
lol that’s not actually how rust is written, it was just a joke
it’d really be written
if x > y { x } else { y }Hah thanks for clarifying. I was joking too and it’s a shame I couldn’t post the results.
Though I admit i don’t know anything about rust. I’m sure I’d like it better than the proprietary garbage i use now that just gets converted to ASM / PLC code in the end. But I can’t skip the middle man. I’m not gonna try but probably 30mins for me to “write” the above.
Besides, how do you make money if I can code something in an hour as opposed to 2 days?

No no no you misunderstood me.
I was being honest, I know nothing of rust. I have however used python in embedded systems with positive results. The product didn’t make it but for other reasons.
Funny you mention java, that’s sorta what I’m stuck in but not like you think. Beyond the fact that it’s a bloated nightmare.
I’m just a low-level programmer at heart but I have bills to pay. The rust stuff was all just a joke… i don’t know it but maybe i should. Thanks for the info.
Saying anymore about what I do is just super embarrassing but i promise i meant no ill will. Excuse my frustration, I’m locked into a proprietary system i have no control over. You would laugh your ass off if you saw it. Anyway, i meant no offense, have a good night!

Isn’t it php?
#define max(x,y) ( { __auto_type __x = (x); __auto_type __y = (y); __x > __y ? __x : __y; })GNU C. Also works with Clang. Avoids evaluating the arguments multiple times. The optimizer will convert the branch into a conditional move, if it doesn’t I’d replace the ternary with the “bit hacker 2” version.

__auto_typeis a compiler builtin, not a library function. It’s not a function at all, the parentheses are for precedence & grouping.
Procrastinator.
Okay, but seriously: “Thief”. Why reimplement it if it’s already available in the language?
Thief
And not feeling one byte bad about it :p
Master Thief
const { Max: max } = Math;
