That means I don't forget about fields (as can happen if you're just doing `person.setX()` all the time). It's easy to see what is what when reading it. I can delete fields I don't want to initialize at the time. Yes, maybe immutable objects are the One True Way, but C# lets me choose (I can label properties with an initializer `init` rather than a setter `set` and then they're immutable).
Kotlin offers stuff like this too because it's really useful toward creating code that's easy to create and maintain. Go also lets you initialize structs in a similar fashion.
Java has come back to us a decade or more late with records. They're not bad, but they're only offering one thing. They don't cover what C#, Kotlin, Go, and other languages have offered for so long.
The annoying thing about Java is that it doesn't feel pragmatic a lot of the time. It feels like the language hates stealing ideas from others. It's Java: people steal ideas from Java, not the other way around. People do crazy things just to get POJOs including Immutables (http://immutables.github.io), AutoValue (https://github.com/google/auto/), Lombok (https://projectlombok.org), Joda Beans (https://www.joda.org/joda-beans/), and maybe more. They generate lots of code at compile time or do funky runtime stuff.
It just feels like Java misses the pragmatic stuff and still kinda doesn't want to handle that. I feel a bit silly harping on things like POJOs and setting data on a new object, but that's a big part of day-to-day stuff and it definitely pushes users away from Java towards languages that seem "better" simply because they don't have Java's oddly strong attachment to not offering simple value objects. Yes, again, records do something - but it feels like Java ignored how people are using Kotlin, Go, C#, and more and didn't go for something that would have been as widely applicable and pragmatic as it could have been.
Java has a lot of great stuff like great GCs (yes), lots of cool research, great performance, and Project Loom is really exciting. I just wish the language would lean a little more practical.

Java should adopt something like the Checker Framework Nullness Checker in its first-party tooling.
https://github.com/typetools/checker-framework
> The Go build tools fit your analogy better.
Go uses two build tools for any non-trivial projects. One write in go.mod and another in Make :D (see this - https://github.com/kubernetes/kubernetes/tree/master/build/r...)
- Support for generic-aware value types (struct vs. class) and low-level features like stackalloc: very valuable for high-performance scenarios and native FFI. See for instance https://github.com/ixy-languages/ixy-languages. In comparison, Java doesn't even have unsigned integers. Yes, Project Valhalla is coming someday.
As well, debatable to some folks, but: properties (get/set); operator overloading; LINQ > Java streams; extension methods; default parameters; collection initializers; tuples; nullable reference types; a dozen smaller features
With Unity, Avalonia/Uno Platform, ASP.NET Core, NativeAOT the sheer cross-platform, cross-workload and deployment flexibility proposition of C# far surpasses Java even if we count in JVM + Kotlin for additional points of the latter.
Now let's talk performance of most commonly used web frameworks. I will save you the trouble of reading long text. Just check https://www.techempower.com/benchmarks/#section=data-r21&tes... and search the tabs for the more popular Java frameworks like Spring, Spark, Struts, Grails, Wicket, etc.
You may find yourself surprised, finding most of them in the bottom 25th percentile. Now scroll back to the top of the page and check where ASP.NET Core is. That's right, more often than not, in the top 10. All that performance, and you get it out of box just by using defaults and then some more. The only exception I see is Vert.X which is both mentioned across the web and also present in the top of the list.
Now, you may say that it's not very representative and there are entries of dubious usefulness in production scenarios (looking at you Just.js). And you would be right. However, the way to get most performance from ASP.NET Core is not using tricks but rather simply writing code like in Node.js with app.MapGet("/users", delegate) and friends.
Despite all this, I still think JVM technologies like Hotspot or GraalVM have an upper hand over what .NET JIT/NAOT is capable of. However, keep in mind the out-of-ordinary performance gains that C# gets with each subsequent release. In areas with significant possibility of improvement like arm64 codegen quality, moving from .NET 6 to upcoming .NET 7 will yield you north of 40% performance improvement. And it was done in significant part by changing the parts of JIT/Runtime that used to be x86-oriented to being cross-platform oriented (e.g. Vector code being plat-agnostic).
I think Hugo might be a better example, as a medium-sized non-trivial project:
https://github.com/gohugoio/hugo
There is a Docker file and some shell scripts, but you build the executable using "go install".
Want more examples? What about database schemas and mapping them to your ORM/other persistence layer solution? I think if you're writing your own model code, you're doing something wrong, regardless of the language that you use. You'll probably mess up or miss relation mapping with something like Hibernate, will miss out on some comments for autocomplete in Laravel and just generally will have an inconsistent persistence layer that will make you waste time.
In most cases, starting with the schema first and using one of the available generation solutions to fill in the application side of the persistence layer seems like the only sane options. Sure, some might prefer to handle migrations in the app side, like Ruby's Active Record Migrations, or something like Liquibase, which are also passable approaches, as long as you don't create a bad schema just so it fits your application.
