I don't know anything about javascript web programming... but want to learn.
My question is : Can I use visual studio 2015 to write, debug and publish(?) javascript web applications.
Again... I don't know if 'publishing' is the right terminology for writing web applications in Javascript... of if you can even 'write' web applications in Javascript...
Any information on the topic would be good to know.
thanks
Yes, you can use Visual Studio to create JavaScript files. It also has tools to publish, depending on the app and environment there are a lot of ways to go about it, and VS can support a lot of them (repositories, FTP, etc).
I recommend just diving in, firing up a blank project and find some tutorials to get you started. JavaScript is probably one of the easiest to develop with (at least getting started) because it has no special needs other than somewhere to write text.

I'm making a RSS reader in flutter, however my requests to the feed are blocked by Cloudflare.
I've been looking for a way to emulate a browser with javascript enabled, since it is needed to pass the Cloudflare test, but nothing seems to have that functionality.
What I need is a simulated browser, that renders the page requested, execute the javascript contained in the page. I haven't found anything that claims to do that aside from webview_flutter, which is a widget and thus cannot be used I my case.
I find it weird that there is no such thing as a simulated browser for Flutter, so I must have missed something.

I'm wondering if there is any serious competitor to Ethereum that's a little easier to use - meaning you don't have to learn yet another programming language (like solidity for ETH) if you know javascript already. The idea is great, but I'd be really interested in an alternative that I can use straight away with vanilla js.
Any ideas?
In theory you can write smart contracts in any programming language as long as you can compile down to virtual machine code.
In the practice, you cannot write smart contracts in JavaScript, because language run-time features make it unsuitable for the task. Because JavaScript is unsuitable for the task in the first place, no one is going to give you tools to write contracts in JavaScript. Writing smart contracts is vastly different from web programming. You need to understand that there is a long multi-year road of learning for you regardless of what you do.
The closest thing you get: NEAR protocol supports AssemblyScript that is a derivate of TypeScript.

I'm soon releasing my paid Electron application.
I have worked for many months on it now, and i need protection on my source code.
i have 2 files, 1. file 5000 lines, and 2. file around 4000 lines.
I need very good obfuscation on this, so it can't be read, and cant be cracked easily.
I'm willing to pay a little bit for a good obfuscator, if anyone knows any good ones that isn't free.
I have tried some different online javascript obfuscators, and most isn't very good, and is easily to read afterwards.
Thank you.
The short and sweet is: what you're looking for does not exist.
At its core, electron is very little but a repackaged webview executing javascript/html/css. The moment you execute your application, the said webview has to have full, concurrent access to the files required by it.
This means your code is there, open, unencrypted, and the only defense you have against somebody peeking is obfuscation. Which, let's admit one thing, falls short pretty quickly when the person digging into the code knows javascript.
If you were using a framework for your app that allowed purely native code, you could write a DRM-esque toolchain for it, but sadly, that's not even an option. Beyond uglifying your code and moving as much of it towards WASM as possible, there's no real other option, just compromises and trade-offs.

How do Slack and Hipchat handle chat on the server side and client side? What languages do they use?
Whenever I'm curious about the technologies used by certain companies I usually check their job postings.
Slack Application engineer job posting:
Our main tools that we use to build Slack are PHP, MySQL, and Linux
Hipchat is a little more vague. They state throughout several job postings that they use PHP, Python, Redis, MySQL, ElasticSearch, and CouchDB. According to a blog post they use PHP for dynamic web pages, and python to implement a XMPP protocol for chat using Twisted.
So at the core it seems like they rely on a PHP/MySQL stack with some addition of other technologies.
I like to check stackshare.io

not a perfect answer to your question but a nice starting point

I've been writing a few tools as standalone webapps that have no server side code and it strikes me that I'm not sure what people call such things.
I like them because they can be distributed as a single file that anybody with a web browser can run. Typically all the funky stuff is done by calling AJAX web APIs like those provided by Stack Exchange, MediaWiki, Google, etc.
The following terms all seem plausible but might also cover other things or not tell the whole story:
client-only
pure JavaScript
standalone webapp
web script
web tool
browser app
Is one of these terms or something else in common use for such apps / tools?
Here's links to some of my little tools on GitHub: travel-se-airport-tags.html, travel-se-1-or-2-answers.html, travel-se-stats.html
There are some much more app-ish examples in the 10k Challenge...
In the fantastic 10K Challenge, they are generally referred to as:
Client-side apps
or
Purely-client apps
But I think your first 3 titles are pretty self-explanatory too.
