Abstract Syntax Trees and Practical Applications in JavaScript
Why do we then have other JavaScript parsers like babel parser, swc parser, acorn, espree and the likes since JavaScript engines have their own internal parsers?

Regex for any js string for representing an object or array containing any number of array or object?
If you're trying to determine if a string is valid Javascript then your best bet is to use a JS parser like Acorn. Trying to DIY parsing with just regex is a good way to end up incredibly frustrated.

What is Babel? And SWC?
Behind Babel is created by an Australian developer Sebastian McKenzie and now consists a small team of contributors. Babel also makes uses a polyfill library called core-js, which in turn uses a JavaScript parser, acorn.

🕶 What it takes to build a Static Analysis tool
At line 3, we import parseScript from meriyah which is a JavaScript parser (could have been babel, acorn, swc, etc doesn't matter for our use case as long as they correctly implement the spec).

[AskJS] What is your preferred tooling when working with JS ASTs?
A simple starting point is Acorn with estree-walker. Not sure if you'll need more advanced functionality but that pair has worked well for my usage. It's also the combo that Svelte uses internally.

Babel is used by millions, so why are we running out of money? (2021)
I do appreciate your transparency, though I disagree with the sentiment that I’m arguing from a position of bad faith.
It’s a self-evident fact that the Babel team has not shown a moment of interest in lowering their role in the JavaScript ecosystem to anything short of kingmakers. Have a gander at their GitHub README and what do we see?[1]
- “Babel is a compiler for writing next generation JavaScript.” Indefinitely.
- Over a dozen sponsor logos. An embarrassment of riches.
- A literal audio recording of a song in praise of the project.
The Babel team has a well documented history of their priorities[2], emphasizing the need for a modular approach that has no exit strategy[3]. At best, we have a case of accidental entrenchment and long term dependence on the Babel brewing as early as 2017![4]
Compare this infinite circus to the humble but popular Normalize.css, which has the express purpose to stop existing.[5]
If the Babel team wants to raise some money, they can start by putting a plan together that would codify an exit strategy. It’s certainly more noble than their current plan of barnacling on to every NPM package…

Reveddit does not work
The problem was I had used some new code, Javascript's replaceAll(), that is unsupported by older browsers. And, the setup I have to automatically fix such issues (called babel) is out of date. So, while this problem appears to be resolved there, I hadn't updated that in awhile.
