Static methods and classes are commonplace and a normal practice in C#, particularly as extension methods (which, quite often, you guessed it, act on data). There isn't that much difference between a type defining simple instance methods and defining extension methods for that type separately if we look at codebases which need to have specific logic grouped in a single multi-KLOC file like, apparently, TS compiler does. There are other issues you could argue about but I think it's more about perception here and structuring the code would've been the smallest issue when porting.

The ship has sailed so not much can be done at this point.

Certainly. The feature is there for a reason. That does not mean that you would write the codebase in that way if you were starting from scratch. You would leverage the entire suite of features offered by C# and stick to the idioms of the language. You would not constrain yourself to writing Go code that just happens to have C# syntax.

It has been ported to a new language before. It can be ported to a new language again. But there wasn't a compelling reason to choose C# last time, and nothing significant has changed since to rethink that.

Why? That certainly wasn't the intent, but I am happy to edit it if you are willing to communicate where I failed.

> I do not understand why Go community feels like it has to come up with new lies (e.g. your other replies) every time.

I don't know anything about this Go community of which you speak, but typically "community" implies a group. My other replies are not of that nature.

But if you found a lie in there that I am unaware of, I am again happy to correct. All I've knowingly said is that Go was chosen because its idioms most closely resemble the original codebase and that C# has different idioms. Neither are a lie insofar as it is understood. There is an entire FAQ entry from the Typescript team explaining that.

If the Typescript team is lying, that is beyond my control. To pin that on me is, well, nonsensical.

Actually, let me fix my previous comment. I was responding to quoted text in your comment which was obviously not your opinion. Sorry.

I still think this is phrased in an unfortunate way. To reiterate, my point is the damage has already been done and obviously TSC is not going to be ported again any time soon. I do not think Anders or TS team are up-to-date on where .NET teams are nor I think they communicated internally (I may be wrong but this is such a common occurrence that it would be an exception to the rule). I stand by the fact that this is a short-sighted decision that has every upside in the short-term wins at the cost and no advantage in long-term perspective. Especially since WASM story is unclear and .NET having good NativeAOT-LLVM-based prototype as a replacement to Mono-based WASM target (which is already proven and works decently well).

Having to prioritize ease of porting for such a foundational piece of software as a compiler over everything else is not a good place to be in. I guess .NET concerns are simply so small compared to the sheer size of TS that might as well accept whatever harm will come to it.

I do not discount your notion, but why?

What damage has been done, exactly?

Call it a lie if you will, but the Typescript team claims to be ecstatic about how the port is nearly indistinguishable from the original codebase, meaning that nothing was lost - all while significant performance improvements and a generally better end user experience was gained.

Perhaps you mean the project has always been fundamentally flawed, being damaged from the day the first Typescript/Javascript line was written? Maybe that is true, but neither C# nor any other language is going to be able to come in and save that day. Brainfuck would have been just as good of a choice if that is truly where things lie. To stand by C# here doesn't make sense.

> I do not think Anders or TS team are up-to-date on where .NET teams are nor I think they communicated internally

Whether or not that is the case, did they need to? Static methods and classes in C# are most likely of Anders' very own creation. At very least he was right there when they were added. There is no way he, of all people, was obvious to them.

> Having to prioritize ease of porting for such a foundational piece of software as a compiler over everything else is not a good place to be in.

Ease of porting was a nice benefit, I'm sure, but they indicate that familiarity was the bigger driver. Anyone familiar with the old code can jump right in and keep on contributing without missing a beat. Given that code is written first and foremost for people, that is an important consideration.
