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.

I've been looking for a VS Code / Git extension, add-on or anything that can help me prevent but to also identify code that is already repeated so I can abstract it away and reuse it.
You know, maybe even build a library for the darn app but I haven't found anything useful and fresh yet.
There is, but it is not free. WebStorm IDE or any there JetBrains IDE show code repetition and also give you a very good insight into your code. you can try it for free for 30 days and if you liked it then buy it.
WebStorm - The smartest JavaScript IDE
Sonarlint is one of the best tool. It says code duplications and makes sure the code is good shape based on the best practices. You can also add that as a plugin in the VS Code.
SonarCube is the actual product you are looking for, it provide lot more than code duplication details.
Sonar Cube will do following things for you
Code Quality Check, it actually analyses your entire code and provides you information about Bugs and vulnerabilities
it also provides you code coverage on new-code which get pushed
it provides you information and graphs about code coverage, bugs etc.
it provides you information about code duplication

Hello, folks!
So here I am - a total beginner in webdev without any profound education on the topic, but still aiming to get a real webdev job sometime soon.
And while the assignments in the courses I've taken employ practical use of the languages(HTML, CSS, PHP, JS, jQuery), they nevertheless lack real-life examples, like something that a real client might want.
Googling on programming challenges as to the aforementioned languages gave out mostly the same; I mean yes, there were some interesting things, but they're still far from the real clients' demand, IMO.
So the question is: where can a beginning webdev find some real assignments to perform in order to comprehend the gist of modern webdev through practice and become able to answer the clients' possible demand? Just for the sake of experience, that is, payment is not obligatory.
Any links/replies will be greatly appreciated, thanks!

For real beginner: https://www.codecademy.com/
But the best thing you can do is trying to implement an own idea / copying an existent idea ... Just think of something basic.
If you need any help, use google first and then ask on stack-overflow to solve your problem.

I'm trying to speed up my website. I used www.unused-css.com/ to trim away excess CSS, but I cannot find anything similar for JavaScript. Is there an online service that can detect the js code being used and then trim away the unused code?
Here is the website with the problem: IQ Tests for Kids
I'm using bootstrap code and it is very bloated. I'm sure that I'm only using a fraction of js because I trimmed down my HTML as well.
The best you are going to get is running the JavaScript itself through a dead code removal process, such as the one provided by the Google Closure Compiler with ADVANCED_OPTIMIZATIONS enabled or Uglify's dead_code option. Some people even combine both of these.
Tree shaking is an even better process you will hear people talk about. But this is more difficult to achieve in your case, because tree shaking involves using ES6 modules, which the code you are dealing with almost certainly is not. Thus it would be a lot of work to get that going, as you would have to modify the code.
Don't know any online tool for that, but there are techniques to do what is called "tree shaking". You can google about it more.
Best my used tools to have it working are webpack and Flow
Webpack is quite general tool to make all kind of magic with JS, while Flow is type checking tool which, if you have type checking active can provide very good tree shaking.
But as you mentioned, you are using Bootstrap, so best place to start looking at would be customize your build:

me and my friend have this develop a game in 18 hour competition on friday, and we have to use javascript (I don't know why) and it isn't very pleasant to work on the same project from two computers and exchange code over a network share folder, is there any way to have a sort of Google docs for javascript coding? Where we can both edit the same document in real time from two different computers? Any time appreciated.
You're referring to "version control".
A good tool (usually the de-facto) for that is Git.
You can then push your code to something like GitHub.
Lots of stuff you can do with this... You can both have individual branches, push them to GitHub, and then "diff" them, meaning you can see individual changes line-by-line and decide what you want to keep or discard. These can be merged to, say, a master branch which represents your final product.
use some sort of source control! Github is an excellent site to use GIT with. Other options include, but are not limited to, SVN and mecurial
SVN, GitHub, TFS are good tools for source control. They will also provide you the ability to check in/check out so that things can be merged in the background. So, if you and your friend are working on the same file and both commit the changes, they would be merged together. However, if you're wanting to see your buddies changes as he types, you're going to need to write something to do this. If you want this type of functionality, there's a cool library out there called signalR (http://signalr.net/). This may be a little overkill but I don't know any text editors out there that will allow you to see someone elses changes as they type. You could probably spin something up with ajax calls but again, that would be overkill and performance would be an issue.

Recently I found this: http://2d-code.co.uk/iqr-qr-code/
This is a QRCode but an improved version. I use some QRCode libraries in some projects and it is a great technology but IQR-Code sound very promising. Less the size (sometimes size is a problem) and can contain more characters on a very small footprint.
To get into the new technology, see also this page.
I want to try and play with these new QRCode to find out if it is really useful and suitable to fit into one of my projects but I cannot find any library for it. I want to find a library that can be used in Android, Delphi, PHP, AS3 or/and javascript. Is there a 'hidden' link on the internet that brings me to such library?
The next thing I wonder about is reading speed. For example, the ZBAR and XZing library reads QR-Codes at razor speed. And what about error correction, is it accurate enough? Because it is using a smaller footprint, is it easy to read by a camera? Is it worth it to invest time in this new format?
Does have anyone more information about this or is there a demo project that I can download?
EDIT 12/01/2018:
Today I found YAB (Yet Another Barcode), initiated by fraunhofer institute. It is a 3D barcode with colors that can hold more data in a smaller form factor. It is free to use, source code available and deserves more attention, take a look at:
https://github.com/jabcode/jabcode
Or use the online demo:
https://jabcode.org/
Is there a 'hidden' link on the internet that brings me to such library?
After researching and googling, it seems that, unlike QR codes, the use of iQR codes is not free licensed by Denso Wave, the owner of the patent.
Is it worth it to invest time in this new format?
The format isn't really that new (it's been around since at least 2011) so, in my opinion, the lack of global success and the fact that it isn't freely distributed answers your question.
