So this is the power of JS libraries...

what the hell are you talking about?

is this it?

No, it occurs in code that is generated using babel and webpack --mode production

How the fuck do you add two zeros together in javascript to get the string "00"?

Why are JS developers so interested in JSON APIs, like what happened to the good old days of locking down what you have created and not making the inner data accessible to anybody

>removing it entirely seems to do the trick
comedy gold

check this:
developer.mozilla.org/en-US/docs/Web/HTML/Element/input/radio

const zero1 = "0";
const zero2 = "0";

const doublezero = `${zero1}${zero2}`;

Remeber to configure webpack and babel to use the code in all browsers :)

Convert the 0s to strings first, but you can't just write 0.toString(), you have to put it into a variable like 'const zero = 0; const zeroes = zero + zero;'. String + string appends

console("00")

you fucking nigger

Now how do I put that into a loop to get an arbitrary number of zeros?
'0' + '0' worked, "0" + "0" didn't.
TypeError: console is not a function[Learn More]

FUCK the JavaScript ecosystem

Unironically this.

math random limit of specific range, for loop from 0 to limit which adds a new 0 to the string every iteration

gonsole.log, holy shit how new are you? console.log("00");

How do you make a custom start page for firefox? Like, how would you configure it? Make a website, then link it as your homepage, or create an addon which loads on new pages? Or is there something within firefox which can just load a local html file?

Make an .html file, store it somewhere on your PC and set it as your homepage. At least that's what I do.

Oh shit, simple as fuck. I forgot you can access local files with the browser. Fucking *facepalm*.

For now, I will use PHP as a backend and using MVC paradigm (Laravel will help me with that).

How do you charge local pizza shop owners for websites? My brother runs a contracting business, and I've seen him pull in $5000 for a paint job. Can I charge this much for a website with online ordering functionality?

you should dig, see what you can find, try to pull the numbers they'd be making and charge accordingly, at least one year of the total of the money they'd be making from that site

You just overwrote console.

Convenience & Maintenance. Having the back-end & front-end meet only at the API means either side is interchangeable.

Front-end + API
>Have to redesign UI and on a different framework
>Can literally just develop the new UI and use the same API, leaving the back-end completely untouched or be versioned to accommodate whatever new shit is needed.

>Moving to a better/faster/more reliable back-end technology
>Just use the same API's and copy over the data. The users wouldn't know any better because the UI stays exactly the same.

Not to mention it's easier to make asynchronous functionality this way.

Server-side rendering monolith e.g. LAMP/Rails/Django:
>Have to change x
>Have to develop and test everything at once.
>Tough shit if you have to move to a different technology. Practically starting from scratch.

I'm not sure if this belongs here, but I guess the dev posts here so might as well post it here.

Would there be an easy way to extract posts/day data for select dates from this site 4stats.io/ ? Specifically I'm looking for the data around and at christmas (~19.12-30.12) to analyze traffic increases/decreases for different boards. This is to detect how many normies are on each board based on the logic that normies are more likely to spend their christmas with friends and family, and therefore have no time to post, while the others spend their christmas here. I'm pretty dumb with these kinds of things so I can't figure out anything else but looking them up manually and typing them down, but that would take ages to do for each board.

I don't often post here, but I see when the site is mentioned via find.Jow Forums.org

There is an API you can use to get the data.
Look at this here: github.com/Nocory/4stats-api#4stats-api
There are endpoints for the live stats, active threads and history.

Thanks. That makes it easy.

Do you guys have a quokka pro crack or key? I can't afford to have one. Only pro version supports file imports. Or any alternative for it?

What would you use

>hurr durr PHP is bad but i can't say why

get out idiot

>fucking why?
it's the only language I've learned along with a bit of JS.
If you or someone could give me a good reason of why I shouldn't use php, I will reconsider it.

Hey guys,

I started web-programming around a year ago. So far:
- I completed Colt Steele's web dev course on Udemy
- I've built a website that utilizes IMDB and TheMovieDatabase with a user-login where you can share movie/tv suggestions with friends
- Built a copy of Jow Forums
- Built a site that lets you host/admin over a play-by-email game. Has chat functionality, user accounts that track what games you are in, and how fast you are likely to take your turns.
- Built a static-paid-website for a local laundromat/fluff and fold. Once they get wifi, they've asked me to incorporate a page that lets people select the music being played if they are locally logged in.

I've done all of this with basic HTML, CSS, and JS utilitizing Node and AJAX. I've become familiar with git and started incorporating it. I just started a class on React.

Curious what I should be doing after this? Is there a point where you are more or less ready to start for a job? I still feel woefully unprepared when I look at others code.

Sup Jow Forums? I've been learning web dev (self taught) the past two months and have moved past HTML and CSS and am on JavaScript. I getting the basics of OOP in JS. Having come from a background where I was mostly using classed based static programming languages (C++ and Javascript), the proto-type based OOP of JS and its weird quirks, like having to define all properties in a constructor, without allowing local class properties is thus very strange to me.

I'm going to do a bit of practice work with it, but I'm wondering how much in the real world JS is used for OOP, specifically in terms of prototypes, classes, and inheritance. In the daily work of a full stack or back end web dev (my job goal for next year), are you using these features much or do you mostly do that with Ruby, Python, etc.?

Thanks, Jow Forums.

you are prepared my man, at least for a junior position you are, more than prepared I'd say, but keep on learning

Have you chuckle-heads discussed the implications of this on the power dynamics of the W3C committees / working groups?

JavaScript is already the new C. Programs are being rewritten in the UNIX language JavaScript, just like they were rewritten from Fortran, Pascal, and other languages into C in the 80s and 90s. The C weenies had to "reinvent" threads and asynchronous programming too, even though they were important features of PL/I, Ada, and other languages many years earlier. C and JavaScript are being used in ways they were never intended for because incompetent "decision makers" believe the availability of "cheap" "programmers" overrides all other concerns. They think 15,600 interchangeable weenies are better than a few good programmers.

Did you even read your code? Get you shit together, user.

what is this?
I just started learning how to code and I don't understand why is it impactful Microshit is creating another web browser

there already have been threads on this

Just use Vue, it's opinionated but better put together

PLEASE RESPOND

For front-end, React uses lots of classes. Components are often classes.

Actual OOP in JS is almost never used.

React doesn't use inheritance in any real sense, it's all composition. Knowing OOP to learn react would be a massive waste of time, especially with hooks around the corner.

Thanks user. As far as I know it is SEO friendly but there is always something that can be done to help improve searches.

I just wanna get a job programming, got myself to an OK level on html and css and to a decent one on Javascript, what's next?

back end and after that javascript frameworks, and after that back end frameworks

you're hired

hell no. what they make it irrelevant, with local biz you're competing with them just making a squarespace or going to a wordpress farm that charge $500 for setup. you have to undercut that, and then make your money charging $50/hr for continuing support when they want to make small changes later

Im already using Vue for some basic stuff, would it be wise to go on a path like:

Php > Node > React

I would also start reading some side stuff like mongodb, sql, and get a little more used to git.

On the other hand, I've seen that on most jobs, specially when it comes to front end, sass and less are a little bit of a common denominator, should I add those to my list?

trips of truth

>should I add those to my list?
probably, just know how to use them, don't prioritize them too much, you are pretty much ready for a job imo.

Learn a back-end besides node.js and you should be good.

Any good tutorial that will teach me how to make a web app with java?
I'm looking to create a browser-based online game

LibGDX is a Java game framework, and one of its export options is for browsers.

You might need some general web app knowledge for your netcode, but a lot that knowledge isn't really necessary for regular web apps and vice versa, so I'm not sure how much help most tutorials and backed frameworks would be.

Try using force

You'd just have to run a curl or something for every search on every site, parse the html response and then coerce it to a common format for your site. It's not difficult to do, just takes a lot of work, and those sites may block you, though there are ways around that
