Have you heard about the Embrace, Expand and Extinguish idealogy? lets think about it:

Javascript 5 (embrace) -> Typescript and Class syntax to Javascript 6 (extend) -> JS (extinguish) with WebASM.

Atom/Electron (embrace) -> Atom fork named "VSCode" (extend) -> Atom (extinguish) as it was developbed by Github company.

NodeJS (embrace) -> incompatible Node Windows fork with IE/Edge JS engine "Chakra" (extend) -> NodeJS (extinguish soon) with chaos of Typescript, Javascript 6 and Github.

"R" lang (embrace) -> incompatible SQL Server 2016 R lang extension (extend) -> R lang (extinguish soon).

Android -> CyanogenMod (embrace) -> CyanogenMod (extinguish) as M$ "sponsored" Cyanogen Inc to destroy CyanogenMod

Linux (prejudge) -> sponsors RedHat, Debian, SuSE, Alpine and Canonical/Ubuntu (embrace), forces unstable backdoored "systemd" -> Linux (extinguish soon)
Reusing the last image I did because I didnt wanted to make more OC stuff cos the few ++ gained arent worth it

When you dual boot ubuntu and windows, then decide to remove Ubuntu because,who ate you kidding, you're not actually using it, then you get bored and want to try the new Linux distro that branched off from arch and vms at the same time so now you're experiencing the wonders of chakra on oracle virtual box....🤔

Where do I even start???? Python is killing me. I am a beginner when it comes to coding but somehow the indentation in Python gets me every time. No matter how many times I follow a tutorial I always end up with at least one indentation error. How do people do this?!?

firstly, does anyone know of an online telegram or whatsapp group where i can ask silly stuff regarding web dev and get immediate answers, just like it is here?

secondly i am trying to learn js and there are just too many related terms that are messing with my brain:
"some features are supported ines5/es6/es15/es16/es17 , some are supported in chrome's v8/chakra/spidermonkey/android browser , some features are only supported in "serverside" and blocked in all browsers thanks to browser's vm environment; babel can't read this code, some features are provided only by node js..."
WHAT THE MESS IS THIS?

All i am trying to do is to write code that would make a website visible to everyone. if by specific browser , i want to target, chrome and its subsidaries and android chrome/other android browsers .
for other browsers am willing to make external converters later but don't want to change my code by 1 bit. And from what i know, each browser (at least the browsers am thinking of supporting) has the complete JS compilers already built in

can i or can i not built a complete functional website with those things?

and finally my main question : how to make custom exceptions in vanilla js? i saw this answer on stack overflow:
===================
function InvalidArgumentException(message) {
this.message = message;
// Use V8's native method if available, otherwise fallback
if ("captureStackTrace" in Error)
Error.captureStackTrace(this, InvalidArgumentException);
else
this.stack = (new Error()).stack;
}

InvalidArgumentException.prototype = Object.create(Error.prototype);
InvalidArgumentException.prototype.name = "InvalidArgumentException";
InvalidArgumentException.prototype.constructor = InvalidArgumentException;

Usage:

throw new InvalidArgumentException();
var err = new InvalidArgumentException("Not yet...");

=====================================

where is the error code? what would be the exception details? what is the line number/timestamp of error?why is that function making an error, i thought error/exception is a class in JS?
