design VS proposals

The project looked really cool, but seems as if it is no longer being worked on.

Solidity to begin with and later on Rust. Purely because at some point there will be an ewasm, EVM compatible WASM and since rust can be compiled to WASM, it is a possible candidate in future.

I see eWasm as a phenomenal mitigation for this problem (allowing effectively any llvm-backed language to participate), but there are most likely still questions around gas-burn and the economic efficiency of real world bytecode.

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.
