How do I learn JS senpai?

I'm making a personal site as a hobby, and as a way to store all the front ends for my little projects. I'm not sure what frontend framework I want to use. Right now I'm thinking Vue.js, but I've also been told that Angular 2 and React are good. Does the speed and small size of Vue.js make it worth it?

You can use + to concat strings.

Strings are implicitly converted to an integer if an integer operation is attempted on them.

Thus, + is trying to concat strings, and - is trying to subtract the integer conversion from a string that can be converted to an integer.

RRREEEEEEE

I've got a python string that i want to print out at the center of the terminal window.

So i thought this would work

x = (terminal width)/2 - string-length/2)
print ' '*x + 'string'

But my string consists of a bunch of functions, so the length counts the name of those functions as characters.

How do i count the letters of the string without counting the function names?

>>58015505
Type coercion.

You can't take a number away from a string so it converts the string to a number.

You can't concatenate a string to a number so it converts the number to a string.

When you say -"2" JavaScript converts the string to a negative number so it's the same as saying "5" + -2 and since you can't concatenate a string to a number, it converts the -2 into a string.

Why the actual fuck do recruiters play phone tag with everyone, and use the excuse "Oh I was with another potential candidate".

Literally doesn't make sense, are they just playing with themselves all day?

Strongly-typed languages also have implicit coercion. Implicit coercion is only bad if it coerces to a less-precise data type.

unfortunately it sounds more literal then not. i have extraneous circumstances and my laptop was stolen by a person (black person). so as you can see I'm on a library computer using an online ide and compiler ot program.

Anyways why in my problem is -

The four adjacent digits in the 1000-digit number that have the greatest product are 9 × 9 × 8 × 9 = 5832

so when i break that large number into sets of four and search my sets the string '9989' is not in there?

That example is not equivalent to the Javascript and Lua ones.

Single quotes denote a character, not a string, in C#, so of course it's going to do ASCII code adding/subtracting.

You can't simulate what was actually being done in C#; C# will not coerce a string to an integer.

Why might that be? Why do you feel some kind of superiority towards another person because they type different text at a keyboard than you do? Do you hate other cultures because of this too?

Last I checked, there were library functions that did this in other /real/ programming languages. I don't get what you have against a small package that basically does the same thing.

>>58016910
I have no strong feelings either way. I'm egalitarian like that.

>>58016904
Then they would have to make a reasonable effort to make recursion practical. Look at Rust - it has ADTs proper, but they're still a pain to use if you have to worry about stack overflow.

Because I have seen the state of the web ecosystem, and I've seen what the JS and PHP types are capable of.

Being unable to learn and unable to look out of your tiny little web box is something to be laughed at. The most important quality of a developer is curiosity.

Saying it's fine because it's just "typing different text at a keyboard" is like saying you can't criticize a rapist because he's just "using is hands differently".
That's gross intellectual dishonesty.

>Do you hate other cultures because of this too?
Wouldn't the world be easier if you could just demonize people who disagree with you?

>Last I checked, there were library functions that did this in other /real/ programming languages. I don't get what you have against a small package that basically does the same thing.
Would you say it's fine to have hundreds of package dependencies each importing trivial 5 lines functions?

This is the level of the "left pad" hell, this is the state of Javascript.
Instead of fixing things or looking for a better language, the community just keeps blindly piling hacks on top of hacks and pissing out a new "revolutionary" framework every 6 months that it will take 6 more months to realize is no silver bullet.

Your usage of the word "need".

No, what's gross intellectual dishonesty is making the assumption that every web developer can't code themselves out of a box.

You have called out a single bad practice, but have made numerous negative remarks about a person's intellectual ability based on the language they use.

Except you're not, because I'm not even a web developer.

Just out of interest how do text editors work?

A linked list of strings or a split buffer (moving text between 2 buffers as you move your cursor)?
Do you work in UTF-8 or decode it into UTF32?
And how is syntax highlighting done, I understand how to write a lexer, but how is it encoded into the text, something like RTF?
What about using RLE on whitespace?

>>58017429
Ropes and UTF-8 muthafuckaaa.

I want to code a Chessbot.

How do I do it? Do I need to hook into the browser? That seems kind of difficult.

It's a generalization, sweetie. It's not dishonest, it's only inaccurate. And even then, not by much in my experience.

"the browser" doesn't have chess on it

Damn straight. I need to get going for a stat final though. Some honest thoughts to follow.

Fair enough, you just appeared to be taking it as fact, when it is a generalization just like you said. It's a common mistake to make, so I figured you were falling into it as well.

>I can't help but notice you're evading the question. Did you really think I was a xenophobe just because I disagreed with you?
No, I was just trying to trigger you, because I did think you were just a neckbeard that didn't actually know anything, and I gave it an honest shot.

I'm literally just typing words into a keyboard at this point, in an effort to focus on something else because I'm taking my last final forever, and I'm anxious about it.

I learned everything by myself, I don't watch youtube videos though. I read books, motherfucker.

>>58018284
Imagine
A = B = C = empty

G: empty -> (empty -> empty)

G could be a function that ignore it's first argument and return identity. You can build such a thing
G = (x. (y. y))

H: (empty -> empty) -> empty
H take a function that produce a non existing for any non existing value (remember that empty is empty). And with that function H produce a non existing empty value.

So H apply to identity would be a contradiction.
If you could

It installed fine but trying to follow the tutorial on the Microsoft page goes wrong saying cl is not a recognized command.

Then why not use a struct with an integer and a float field?

>>58020000
Sounds like poor design to use the same struct for both, and they should use a tagged union even if so.

>>58020036
if I'm reading this correctly you can put more info into that string like if you only want a resize if the original is smaller/bigger than the dimensions in the string.
Again I've never worked with that, just what I pieced together from a quick google search

This tbqh. Read a book you fucking memester.

I feel like programming in F# today with .NET Core. Someone give me a programming challenge.

>>58020015

You mean 65535x65535 pixels?

>>58020149
bootloader

>>58020080
That's such a terrible way to implement it. What is wrong with C programmers? And why should that be the library's responsibility in the first place? Just check if it's smaller or whatever before resizing, ffs.

>>58020157

Can't do that in F#.

>>58020149
10000 takes five characters. five bytes
now compare that to INT32_MAX

>>58020177
?
Why isn't your language of choice Turing complete?

>>58020149
C++ Compiler

>>58020161
not necessarily the c programmers fault, jmagic and Rmagick have the same imageInfo structure and use strings (or geometries) as well, maybe it was just the simplest way to have very similar implementations in different languages

>>58020228
also apparently you can also use postscript page size nicknames (like A0 or Letter) as sizes

>>58020015

I'm talking about type widths. Integer is YUGE for image dimensions. You won't need anything bigger than short, most likely (as larger images tend to cause crashing with most software).

>>58020177
Make an assembler in F# then make bootloader in assembly. Also checked.

>>58020184

I thought we were comparing to short. Strings should never be used for storing image dimensions.

Also, any integer type storing dimensions should be unsigned, not signed.

>>58020204

It is turing complete. I don't think there are compilers for F# for freestanding environments, however. it needs the CLR.

>>58015327
Yeah he should write haskell instead, amirite?
Its useless, but its cool!

Why are the tripfags in this thread such massive wincucks?

>>58015762
store the string created by those functions in a variable and then just use len(var)

c# is shit, java is good.

>>58020377
>java
>good

>>58016064
it's because you're breaking up the string into four characters, despite that not being all of the adjacent digits

for example, you're doing
7316
but not also
3167

Does any other language has anything nearly as comfy as extension methods combined with delegates?

Is there a non retarded regex tester online somewhere?
regexr doesn't handle multi-line very well. or at all, basically.

Everything else I find is expecting really small snippets.

>>58020534
>>58020569

There is no such thing as a negative quantity of pixels.

>>58020678
python

print (''.join("desu" for _ in range(1000)))

>>58020611
https://en.wikipedia.org/wiki/BMP_file_format
Search for "negative".

>>58020678
I don't know about delegates, but

Perl:
print "desu"x1000;

Ruby:
1000.times do
  print "desu"
end

You said 'dimensions', but never specified that we were talking about images.

Dimensions are always absolute you tit. -5 on an XY plane still has a length of 5 from the origin.

Is the transition between Java and C# difficult? Or could I jump into difficult projects and just google the syntax as I go?

>>58020814
>Or could I jump into difficult projects and just google the syntax as I go?
that.

>>58020814
C# basically accounts for anything sloppy you would have done in java.
Also it's less retarded in literally every aspect.

C# is literally Java++. It takes the 20+ years of legacy bullshit and poor design and fixes it.
Look up LINQ when you get cozy. It's bomb.

>>58020851
>Also it's less retarded in literally every aspect.

There are (shockingly) a few things that Java did right and C# lacks, though.

>>58020882
Examples?
Not in a hostile way, I'm genuinely curious.

>>58020912

readonly/const are fucking garbage and final is better. Can't think of any others at this exact moment, but I'm sure they'll come to me.

>>58020973
Efficiency-wise or syntactically?
Because honestly I prefer Readonly/Const options vs a single Final option. Makes it more clear what the intent is.

>>58020994

readonly cannot be applied to locals and const only works on compile-time values (which will invariably be primitives).

Pretty shitty, desu.

>>58021027
That doesn't seem bad in practice though. You shouldn't be using constant/finals in local scopes and constants only work on compile-time because it's constant, it SHOULD be a compiled value rather than JIT/runtime
