(Trailing space on the last line)

Riker

@Downgoat what about const? I didn't realize let != var

Downgoat

@Riker with let the var is block scoped

Riker

20:11

yea but should I use const when applicable?

i.e. when I'm not goign to change it

Downgoat

yes

do note const does not prevent mutation

TuxCopter

wat, there's a clause in the Skype TOS that forbids publishing reputation-damaging opinions about it

Phoenix

@HyperNeutrino s/e/es, with no trailing space. Without /g, it will only replace the first e.

user165474

>_> you win

ArtOfCode

and you're missing your trailing slashes both of you :P

user165474

20:12

lol

user165474

Someone was complaining about that to me a while back. :P

user165474

Or, s\e\es just to tick off tchrist

Phoenix

@ArtOfCode Do you need those?

Not in Vim, at least.

ArtOfCode

@Phoenix Vim ain't the original syntax

original syntax is from sed, where you do need them

Business Cat

If a challenge has only 1 input, I'm allowed to submit a function with 2 parameters but just uses the default value for one, right?

Phoenix

20:15

No, you can't take an extra input even if that input is irrelevant.

ArtOfCode

@Phoenix sed says this about it: sed: -e expression #1, char 11: unterminated `s' command

Phoenix

e.g. you have to use ()-> and not i-> for lambdas.

Riker

@Downgoat mutation?

Phoenix

@Riker const does nothing if you try to modify the variable, it just throws a warning.

Business Cat

Are you sure? I actually remember doing exactly what you said before

Riker

20:16

@Phoenix oh, okay

such as x += 1?

Business Cat

That was a while ago though

Riker

but it will error on x = 5?

Phoenix

No. It will allow both operations.

It will throw a warning, which doesn't affect execution.

Downgoat

@Riker yes

Riker

@Phoenix actually it errors on both

> const x = 5;
undefined
> x += 1
TypeError: Assignment to constant variable.
> x = 5
TypeError: Assignment to constant variable.

Phoenix

20:17

Might be implementation specific.

user165474

Darn, I can't figure out how to do this in Jelly.

Riker

I trimmed out the traceback of the 2 errors but yea

Chinmaya B

@Mego Oh that's hilarious analogy!

Riker

@HyperNeutrino specifically the looping, right? I don't know how to loop either

the other 2 should be easy though

flawr

@Riker +

Riker

20:18

reddit is blocked atm, screenshot?

user165474

@Riker No, more so the pausing part.

Downgoat

@Phoenix should be unless you're using an non compliant implementation

Riker

and/or copy paste the text

@HyperNeutrino ah

Phoenix

@Downgoat I remember it working hat way in Edge

Which is... not surprising in the slightest.

Downgoat

There's your problem :P

user165474

20:19

¯\_(ツ)_/¯ Oh well.

Riker

@Phoenix #justedgeproblems

user165474

I'll just wait for Dennis and learn from him. :P

Riker

@Downgoat so const would error in something like this, right?

for (var i = 0; i < dates.length; i++) {
    let item = dates[i];
    let year = item[0];
    let month = item[1];
    let day = item[2];
    if (currentDate < new Date(year, month, day)) return i;
}

with s/let/const/g

Downgoat

Should be OK

Riker

won't year,month,day get redefined every loop iteration?

flawr

20:21

@Riker sorry, would be way to long

Downgoat

Yes but const is also block scoped

Riker

@flawr :/

Phoenix

No, they go out of scope and are destroyed every loop iteration

Riker

can you post the imgur link then?

@Phoenix oh, cool

user165474

I remember once somebody said I was missing trailing slashes on my regex, so I used s/$/\//. :P

Phoenix

20:22

In Java, you can only declare constants in the scope of a class, so this is a nonissue.

flawr

@Riker it also includes a bunch of links. it is a polandball about switzerland, and the comment section is worth reading=)

Riker

ah ok

I'll prolly try later then

@Phoenix kek

Downgoat

@Riker m.imgur.com/t/goat/QOZJw

Phoenix

And by nonissue I mean "Why define a behaviour when we can just make it illegal instead"

Riker

@Downgoat lolwut

so tl;dr: almost always use let instead of var, and use const when applicable (in place of var)

Phoenix

20:23

Aren't let and var the same thing?

Riker

var is globals, let is block-scoped

Downgoat

When defining globals for browser always use var

Riker

iirc

Phoenix

Ah

Downgoat

there is reason var does what it does

@Riker var is scoped to function

user165474

20:24

tl;dr: Don't use JS. :D ;P

Riker

@Downgoat ah

@HyperNeutrino yea but brython is slow af

Downgoat

@HyperNeutrino no it make perfect sense for browser

Riker

and it's for a website

user165474

¯\_(ツ)_/¯ True. But PHP exists as well (though I think it's even more confusing).

Phoenix

Is it directly browser JS or server-side node.js?

Riker

20:25

#1

Phoenix

@HyperNeutrino We all know that the best option is Rails.

Downgoat

@Riker pffft #reactmasterrace

A: Sandbox for Proposed Challenges

Undefined Behavior question I'd like to ask a question like this: Create a program that should throw an error on compilation but doesn't, then results in undefined behavior when run. But I don't know how to title it, if this phrasing is OK or if it will be on-topic. And what tags should I...

Riker

@Downgoat googles

> facebook.github.io

oh god why

Phoenix

20:26

^

Riker

@Downgoat react looks like javascript with more java

is that right?

Downgoat

Considering Facebook is multi billion dollar company I'm not sure why they can't shell out $8 for a domain

@Riker its basically JS but with HTML inside of it

Riker

ah

I did'nt realize extends was JS

Phoenix

Why would you want server-side html?

Riker

or maybe it's not idk

Downgoat

20:27

@Phoenix how else do you serve custom generated pages?

Riker

good point

Phoenix

That's not what I meant.

Downgoat

Most of the time you don't want to load empty page and do AJAX req to get data

That is bad for many reason

Phoenix

Why do you need a library to directly integrate the html into your code, which is what you described React to be.

Downgoat

You could use pug but less powerful

@Phoenix its a more or less an approximation

Riker

20:29

@Christopher fwiw later you can try !<imageurl> if it doesn't immediately onebox, see here

sometimes things like ?<x> on the end of the URL bork auto oneboxing

Phoenix

*googles*
*learns nothing but day is made better*

Downgoat

I mean better would of been it integrates HTML framework and structure with JS OO but eh

Riker

so why react instead of plain JS?

I'm not really doing that much, just a bit of DOM manipulation

Phoenix

Riker

and it's all clientside atm because I'm using github pages

Downgoat

20:30

@Riker I reccomend google JS DOM API

Riker

@Phoenix dat face tho

@Downgoat ??

Downgoat

though react is really only used with dynamic apps with significant server side component

@Riker sorry point is JS DOM manipulation JS hard >_>

Riker

ah

Phoenix

Personally I prefer the latter-day paradies, which replaced O'Reilly with O'Rly

Downgoat

I am fine with using no react but I also am fine with eating tin can

Riker

20:31

*parodies?

@Downgoat I have like 3 lines of relevant DOM manipulation code

Downgoat

Ah ok yeah no react then

Phoenix

@Riker That's not an actual book, but people make fun of O'Reilly book covers all the time because of the stupid animals

Riker

not even using jquery, the only thing I'm doing is document.GetElementsByClassName("container")[0].innerhtml = "text"

inb4 "use jquery"

@Phoenix ah. I was pointing out the typo though (para vs paro)

Mithrandir

You mean tiepoes?

Riker

@Mithrandir no I mean typeozies

user165474

@Phoenix Wow. lol

Riker

@Downgoat you use digital ocean, right? How much is the vihan.org server?

in terms of cost and memory

Downgoat

@Riker $10

Phoenix

@Riker 5$/month is TIO

Downgoat

20:37

OVH might be better deal in terms of price

Riker

oh, really?

Phoenix

Which means with the referal link on TIO, you can get 2 months for free.

Riker

oh, hm

Downgoat

@Riker you can get cheaper version for $5 but if you're running complex app it'll probably run out f memory quickly

@Phoenix AFAIK TIO uses multiple droplet

Phoenix

Well, yeah. But each individual arena + frontend is one 5 dollar droplet.

Assuming Riker isn't going to be running arbitrary code for people, he only needs something as performance-intensive as the TIO frontend.

Riker

20:39

@Downgoat it's a simple website

Phoenix

Which is the cheapest 5$ one.

Riker

so yea, that should be ok

@Phoenix it's arguably less intensive than that

thanks for the advice

Downgoat

@Riker ok, I reccomend nginx and no Wordpress in that case

Riker

I've heard bad things about WP and I need a different format anyway

Phoenix

tio.run/nexus/#community see Referrals section

Riker

20:41

already bookmarked that

just checked, my website is only 320 mb anyway (full source, unminified) so I should be ok with the 512 mb storage droplet

Phoenix

Digital Ocean charges hourly up to a certain monthly cap, so you can create a droplet, test a thing, and destroy it again and pay less than a cent.

Downgoat

@Riker it come with 20gb of disk and 512mb of ram :P

Riker

oh, I thought it was 512 mb of disk

idk why but lol

All but one message on the starboard is for red team

*glares at trichoplax*

Geobits

Only because teams are broken

I should clearly be blue.

Phoenix

I'm not sure what makes you think that.

Geobits

Because 1) I like blue and 2) It should be based on site IDs, not chat IDs, so it lines up with the red/blue challenges on main.

But mostly 1

Being blue on main and red in chat is weird and wrong.

Riker

lol

Geobits

But mostly 1

Phoenix

20:52

Geobits

Boo red team

Riker

lol

Phoenix

But does this blue team have a flag???

Riker

prolly

here ya go

Phoenix

ಠ_ಠ

Riker

or an even better one, compete with stock photo watermark

Feel free to complain here:

ATaco

aaaaaaah

Geobits

Closed as "not easy" :/

@ATaco You're welcome

ATaco

Technically not possible.

Talking in TnB doesn't mean you have a CodeGolf ID

Geobits

True, but you could use the parent site ID (it's linked from the avatar popup). If they want it to line up with the site, then it's up to the user.

Riker

20:56

@Geobits -1 closing as "not easy" is not acceptable

cc @ATaco

please close instead as "was proposed by geobits" instead

Geobits

And if you don't have a PPCG id at all, you wouldn't care if it didn't line up with the challenges.

user165474

How are Minecraft PPCG answers scored? I remember there was a relevant meta post but I can't find it.

Q: Programming in Minecraft (Redstone) - how to measure program size?

Since programs may be created in vanilla (un-modded) Minecraft using redstone to create logic gates (and more), someone could create such a program for a challenge on this site. How would such an entry be scored? Some possible scoring methods: Blocks used (placed redstone counts as a block) R...

@Geobits not even hard :p

user165474

Thanks.

Q: Translate an alien base system

Our regular base system for time is a little odd. 60 seconds per minute, 60 minutes per hour; then 24 hours per day, and 365 days per year. This is unorganized and somewhat hard to follow compared to our base system for numbers (10 units per ten, 10 tens per hundred, 10 hundreds per thousand...)...
