Need ideas with modding TCOAAL
I don't need/use IDA, Nemlei just used https://obfuscator.io/, which just obfuscates the crap out of the code using various known methods (which I won't go into detail, it's public knowledge) and an un-obfuscation was cooked up by others. The one fucked-up thing the website does is randomizing function names, it just changes every variable/function name. We can't "un-obfuscate" those, so it's up to our brains to figure out what the code does, and change the names back.

Question about backticks
I was considering using a obfuscation library (https://github.com/javascript-obfuscator/javascript-obfuscator) and noticed in the usage example that backticks are used and the javascript is enclosed within. The issue is that my javascript already has backticks from using template literals so my code then errors out.

Which options do I have to hide/obfuscate/bytecode my main source code but not the renderer? Angular inside.
What I ended up doing is having two build steps, one for renderer and other for the main process, in the main process build I use https://github.com/javascript-obfuscator/javascript-obfuscator. Works pretty fine.

Misty Programming Language
This is the spec for the language Douglas Crockford (author of the book "JavaScript: The Good Parts", the JSON specification[1], JSLint[2]) had explained in his famous talk: "The Next Programming Language"[3].
The "big things" in the language are the Actor model, favouring immutability and capabilities-based security.

JavaScript Is Weird
Someone should write a book about this [0] and a tool to automate checking your JavaScript code [1].

How To Secure Your JavaScript Applications
One way to achieve this is by using linting tools like ESLint or JSLint. These tools automatically analyze your code for errors, stylistic inconsistencies, and potential security vulnerabilities. By customizing the linting rules to align with coding standards and best practices, you can identify and rectify potential security issues early in the development process. Linting helps maintain a clean and secure codebase.

JavaScript import maps are now supported cross-browser
>Does this mean that in theory i could skip the build/bundling step entirely?
You can but you must write your app in something the browser understands (js not ts, css not sass etc) and use native modules. For example, here is the test harness for a custom module, written in pure html with no build step: https://github.com/javajosh/simpatico/blob/master/combine2.h.... Here is a more complex (and much older) example from Crockford: https://www.jslint.com/
And yes, the experience developing this way is quite nice!

Find ES6 features in any JS code
I came across a problem where I had to find the ES6 features used by any javascript project and other data regarding their use. When I reached out to stackoverflow, I could find only one relevant post which asks you to use linters like jshint/jshint or compilers like babel. Jslint didn't seem to report anything specific to ES6 and Babel converts all the ES6+ features to ES5 but doesn't report anything regarding which constructs were used or how many times they were used. However, Jshint reported all ES6 features used in the code along with some metadata. And, to suit my needs, I ended up writing a python script that calls Jshint on all JS files in a project and presents the features used in the project and the number of times they were used across all files. You can find the code here : jsHintRunner

The Why & How To Create A Front-End Website Testing Plan
Javascript Linting parses and checks if any syntax is violating the rule. If a violation occurs, a warning is shown explaining unexpected behavior. Use the online version for small projects: JSLint, ESLint or JSHint. For larger projects, it is recommended to use a task runner like Gulp or Grunt. Linters ensure developers are following the best practices as a result of which few bugs appear during project development.

Disambiguating Jamstack and MACH
Programmers of classical languages hate JavaScript because it's prototype-based, dynamic and weakly typed (among other complaints). It's also the number one most in-demand programming language in 2022 according to a number of independent surveys. JSLint can help you write better JavaScript and JSMin can minify your code before deployment. These tools were created by Douglas Crockford. I would recommend his books JavaScript: The Good Parts for programmers coming to JavaScript for the first time, and How JavaScript Works for experienced JavaScript programmers.
