proposals VS ts-morph

The proposal of "syntactic tail calls" to provide an explicit syntax for tail calls, co-championed by committee members from Mozilla (responsible for SpiderMonkey, the engine of Firefox) and Microsoft, was a response to these concerns. However, this proposal is now listed among the TC39's inactive proposals, possibly due to diminished interest, which may stem from the infrequent use of tail recursive functions in JavaScript.

Then there are proposals for new features. Some proposals move through quickly, though some of these will never make it into the spec. They can be available months or years in advance through Babel plugins and other tools. Be aware that these allow you to write code that may never become valid JavaScript, but they can be useful for simplicity and readability, so long as you understand the requirements.

TC39 Proposals

As for what’s new, well here https://github.com/tc39/proposals/blob/main/finished-proposals.md you can research anything from that list that doesn’t look familiar to you.

The latest version of the ECMAScript standard is referred to as ES2022. However, there are almost always something new cooking, which you can use (ESNext) if yo have a javascript engine that implements it, or if you use a polyfill which implements some particular feature for earlier javascript engines.

[2] tc39 on Github. ECMAScript Finished Proposals.

Check out the proposals page for info on what (may be) coming to JS: https://github.com/tc39/proposals

I recently came across an incredibly powerful tool called ts-morph. It's an Abstract Syntax Tree (AST) code analyzer and manipulator that can easily locate class declarations and their references. Just remember, it only works on TypeScript files. To use it, we created a new "build.ts" file and harnessed the full potential of Bun's API. Because ts-morph only understands TypeScript files, we bundled our files accordingly.

I'll definitely look into these two generation suggestions, one I found from a quick google search was [ts-morph](https://github.com/dsherret/ts-morph/tree/latest/packages/ts-morph), but I haven't looked into it further yet.

ts-morph may also help.

The declarations (functions, variables, classes ...) and their docs are extracted with a custom API extractor I built based on the ts-morph library and the TypeScript compiler.

There are a couple of ways. Like you mentioned Babel has various features that count as language extensions and there's also SweetJS. I've been interested in exploring the compiler API personally and ts-morph.
