How to make your own programming language in JavaScript
What's cool about Esprima syntax is that there are tools that generate code based on their AST. An example is escodegen which takes Esprima AST as input and outputs JavaScript code. You can think that you can use just strings to generate code, but this solution will not scale. In this tutorial, I show only a single if statement but you will run into a lot of problems if you will have more complex code.

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.
