https://www.typescriptlang.org/docs/handbook/release-notes/typescript-3-7.html#the-usedefineforclassfields-flag-and-the-declare-property-modifier has some more information around this, and the declare keyword on class properties. In a nutshell, declare just means "don't include this in the final JavaScript code", which is exactly what we want here. 👍

@MichaelSun90 Do you have the time to run a few of the benchmarks before / after this change and document the difference here in this pull request body? 🙇‍♂️

Here are the benchmark compression (rpcrequest-payload-tvp.js is not in here, run into a "No collation was set by the server for the current connection. Error"):

@MichaelSun90 I assume the Node.js version you used was v16? The results are a bit all over the place, I'd have expected them to be a bit more consistent in the improvement. 🤔

Obviously, the token parsing ones should be the one that show the biggest difference, because that's the part that's most affected by the performance degradation coming from using class properties.

The benchmarks that test full request cycles are expectedly less affected, because token parsing is a small piece of the overall logic that gets executed in these benchmarks.

The bulk-load benchmarks and the request payload generation benchmark should also only show minimal changes, but there's quite some variation in there. If you have a lot of other processes running on your machines, that might make the benchmarks less accurate.

I am on node 18.17.1. 🤔 The improvement on the token parsing part looks pretty promising.
