runtime VS Acorn

If you're not already familiar with Acorn, I recommend checking out the official docs to learn more about it! Basically, it is an app platform that makes it easy to deploy cloud applications and their dependencies by describing them in a simple Acornfile. Instead of configuring all of the required Kubernetes manifests to run our application in the cloud, we can just use an Acornfile.

Using open-source command-line tools Draft and Acorn, we'll containerize and deploy to AKS in just a few steps! Let's go 🚀

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?

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.

To render UI I use Svelte. To parse JS files I use Acorn JS in Web Worker.

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.

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).

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.
