Difference between esnext and es2022 build target?

[hyperknot]

What is the actual difference between newer es20xx versions and esnext when used as a build target? I mean, the differences between those years are mostly features which are not transpiled/polyfilled anyways. So what's left? Did module loading change at all in the recent years?

I mean, is there any actual difference between using es2022/23 and esnext in build target?

es2022 and es2023 does not have any difference. It was added for consistency (see microsoft/TypeScript#57683).
es2023 and es2024 has a difference (esbuild try).
es2024 and esnext has a difference as well (esbuild try).

Thanks for your reply. Can you tell me what are those called, and how can I find it on this website? I mean just because I started with that table and couldn't find "using" for example.

/foo/v is called "RegExp v flag".
using a = foo() is not on that page. It is on https://compat-table.github.io/compat-table/esnext/ and is called "Explicit Resource Management".

Do these transformation apply only to the user-written code, or to dependencies as well?

So if I have a policy to only write code without these features like regexp v flag and "using", can I just set it to esnext? I mean I can control the code I write, but not the one in dependencies.

It applies to any code that is included in the bundle.
