C++ vs Rust vs GO
Go isn't really low level. It has a runtime and GC. It's basically a popular alternative to Java and C# for web services. I remember reading that it isn't that fast, as claimed. Rust is much closer to being a low level language. It doesn't have a runtime or GC and that means it's more suitable for lower level programming. I think it's a good stepping stone toward the lowest level which is the C language. My company mainly uses C#. We choose Rust for a couple projects because it can export a C like FFI. This means basically every language can import that library. It's high level and modern with great package management while accomplishing low level FFI without losing memory safety. C++ will never go away, it's too deep in very important projects. It's definitely low level, but not as low level as C. More on reddit.com

September 22, 2021Is Go easier to learn than C, C++, Rust?
It's simpler than Rust / C / C++ and you're likely to get memory savings from making the switch from Node. Just as an example, I rewrote a couple discord bots I had in Node to Go for some POC on savings. Went from 90 - 120MB of RAM in the Node version to about 8 - 12MB of RAM running the Go version, along with lower CPU usage. I find it easy to learn and generally fun to code in. Definitely recommend having it in your programming toolkit. More on reddit.com

I currently write code in C#, using Console Application, Blazor, or WebForms
Question 1:
I'm looking at going into a low-level language. My interpretation of what a low-level language can actually do (like C++, Rust and GO) is quite limited. What can these kinds of languages offer which C# can't? Although I'm pretty much fluent in coding in C# I still struggle reading about the technical side of languages, so I'd prefer noob-friendly answers like C++ can make an application dedicated to cheese graters, whereas C# would be better creating an application dedicated to cheese.
Question 2:
I'm looking for a language that is still going to be big in 20 years - these three seem to be the biggest, Rust and GO being newer, but C++ still being in applications like Googlebot (backend) despite being ~40 years old. Which would be the better option for a newbie, and why?

April 20, 2021 - Go is garbage collected – which means that developers don’t need to manually manage memory; furthermore, the garbage collector can be turned off too but again, I don’t have experience with that but even with that, Go has an in-built scheduler and I don’t think one can disable that and write code directly on the system · On the other hand, Go is somewhat restricted – there are many features available in other languages like Rust or C++ that doesn’t exist in Go – for example operator overloading and inheritance.

January 13, 2024 -
I am not a pro developer, but I code some small tools for myself time to time, in JS. But I hate how much memory and disk space node or even bun take up. So, I was thinking of learning a simple binary compiled language, both to just learn more programming and to use it for my little personal projects. From what I've read so far, everybody seem to say that Go is the easiest to learn between C, C++, Rust, and it's fairly fast and optimized. What would you say? Is that true? What would you recommend me learn?

Rust is definitely harder to learn, and I don't think it's even close. C++ is a much bigger language. I don't know that it's any harder to learn a subset of C++ like 99% of C++ programmers do. If you wanted encyclopedic knowledge of every corner of the language, it'd be harder to learn. Plus there's a lot of standard library, boost, etc. that's not exactly part of the language but it's definitely part of using the language. C is probably easier to learn, but a much bigger pain to actually use. Like the lack of strings, resizable arrays, hash/dict/map stuff, etc. You can DO all those things in C, but it's very "roll your own". Go is closer to "what if Python was performant?" Except also statically typed and also much less library support. Honestly, probably worth getting your feet wet with all of them. Somewhere past hello world, but not necessarily trying to become proficient in them. At that point, you'll know which you want to dig deeper into.

April 1, 2022 - According to the Stack Overflow Development Survey 2021 , both Rust and Go (known also as Golang) have a special place in developers' hearts. According to the survey, these programming languages are loved by almost 87% and 63% of the respondents, respectively. This score puts Rust at the top of the list. However, does Rust deserve to be the developers' blue-eyed boy? In this article, I will compare these two popular solutions, covering aspects like memory management, concurrency, tools, performance, learnability, and more – to give a big picture view of Rust and Go.
