@hasherr I need to talk to you when possible :D

Jovito

Anyone fluent in Javascript around here? I'm having trouble understanding its object model, prototype chains, so on.

Books only confuse me more and articles I've read didn't help.

@Almo @Wardy @Lasse anyone?

Wardy

sup ?

js is basically just c# without the type safety

or any concept of standardisation ... at all

but it sort of works for the problem it solves ... getting code in to the browser

so what's you're issue ?

Jovito

C# has first-class functions?

Wardy

but then js doesn't really ... it just has functions

Jovito

oh god

Wardy

22:11

and no concept of scope like c# does

being "technically correct" though ... js does and c# doesn't

but it's just a fancy way of saying I can or can't define a function outside of a class

you also have closures in js ... functions that basically execute themselves as part of being defined

Jovito

from Javascript: The Definitive Guide: "JavaScript derives its syntax from Java, its first-class functions from Scheme, and its prototype-based inheritance from Self."

Wardy

$(function () { ... });

yeh don't worry about that just write the code as you would write c# and it should for the most part work

Jovito

I don't really know C# yet :P

But anyway, what I'm trying to do is a pong clone to get a grasp on the language.

Wardy

well then the best advice I can give you is ... learn 1 language at a time

Jovito

I want to inherit objects from a Sprite prototype.

Wardy

22:15

Jovito

But the Sprite constructor requires a filename string to be passed in and Javascript doesn't have anything like a super function.

Wardy

just ajax load any images ?

Jovito

3 mins ago, by Wardy

well then the best advice I can give you is ... learn 1 language at a time

I am.

What made you think I wasn't?

Wardy

function GetImage(name, handler) {
   $.get("images/" + name), function(result) { handler(result); });
}

@Jovito I thought last time we spoke your trying to do stuff in c#

Jovito

You don't understand. My problem is inheritance-related. I already got the image loading function.

Wardy

22:19

eh ... inheritance in js ?

why

Jovito

Nope, that was another project and it was in Python.

@Wardy Why not?

Wardy

I guess i've never really written anything in js that warranted inheritance ... since js natively has no concept of a class it feels like a pointless feature of the language to want to use

hasherr

@Pip Sup

Wardy

I just tend to build basic objects instead

Pip

@hasherr uh.... can we move to Skype?

Kevin van der Velden

22:21

Never

Pip

sh, you! :)

/bin/sh to be specific

Kevin van der Velden

Jovito

@Wardy Instead js has prototypes. Objects inherit properties from their prototypes.

Kevin van der Velden

@Pip $

Wardy

yeh i know

Pip

22:22

@KevinvanderVelden :D

Wardy

but prototyping is not the same as inheritance

prototyping is about definition inheritance is about combining definition (composition but not technically the right word)

hasherr

@Pip Briefly, sure. No more than 10 or 15 minutes. Is that sufficient?

Pip

yeah, don't even need to call, just text

hasherr

Sure, I can stay on for however long then.

Pip

coolcool

Veritas

22:33

what's everyone up to ?

Jon

nothing

Jovito

@Wardy Nevermind. I'm afraid if I go any further that I'll end up killing myself.

Wardy

lol

welcome to js

Icy Defiance

@Veritas trying to get a dev environment set up for C++, on Windows, using Vim

having all sorts of fun

dwarf fortress definition of fun

Veritas

it's why I prefer a linux partition for development

most stuff is either ready or extremely easy to install

Icy Defiance

22:41

lol yeah but dual-booting is more annoying in the long run

Wardy

could vm a linux distro ?

Icy Defiance

yeah that was suggested earlier. it's a better option, but still has some problems.

so far I've gotten everything working after enough effort

current problem is unrelated to windows. I just don't fully understand how .vimrc works.

Jon

So sad mars one, is a bullcrap operation -- as expected.

Part of me kept hoping it wasn't.. but all signs were pointing to one thing... and lo and behold.

Wardy

@IcyDefiance looks like windows 10 comes with hyper-v built in

so things could be looking up :)

Veritas

is sublime text free?

Icy Defiance

22:47

yes, but it'll nag you to buy after every 50 or 100 saves or something

just hit cancel and it'll keep working

more than worth it imo

Veritas

I love it's highlighting

probably the best I have seen

its*

Pip

holy shit MC got a huge music upgrade

Almo

23:03

@Jovito I know a little, but I couldn't help with anything super sophisticated

Jovito

@Almo have you used prototypal inheritance?

Icy Defiance

ooh some guy dissected a Pentium III cpu imgur.com/a/ynPeX (hit load entire album at the bottom)

Wardy

23:17

@IcyDefiance thats awesome

Wardy

23:37

lol

i think some pieces are maybe not quite in the right place
