based on these 2 I can even make js the fastest.

>>61308282
The funny thing with these benchmarks is it depends on implementation, so just wait until someone writes a better loop in C99 that has aliasing guarantees using the restrict keyword.

Rust does that fancy type checking or whatever so its faster than C which doesn't IN THIS PARTICULAR BENCHMARK okay

classic asm.js, constantly 2.5x slower than native C...

A lot of work went into Java to make the performance not suck as much, and if you know the tricks it does you can properly optimize.

>>61308763
Except it's not the same thing at all with Rust. The very nature of Rust allows it to be a direct competitor to C in terms of performance. In fact, being faster than C is one of their goals.

Rust?
https://github.com/redox-os/kernel

>>61308887
I understand your point, but you picked wrong words.

1) You can program in whatever language you want but eventually it's translated to native assembly language of this cpu.

2) Unlike Java or Python, with C, the abstraction is minimal, C was known as portable assembly and the translation is fairly straightforward, almost 1:1 what >>61308887 means.

3) 99% of the assembly programmers cannot write a better assembly code than an optimizing C compiler produces for the same algorithm. (with the same selected instruction subset).

I program in C and x86 assembly since 2017 and as much as i try, gcc -O2 always outperform my direct assembly code.

So with the same algorithm and same cpu and the same instructions, if Rust is faster than C, it's by definition a flaw of C compiler. Because C is lower level than rust so the conversion (compilation) is more straight forward.

>>61308494
It's not like learning C takes longer than a weekend at most. The standard library literally fits on a postcard. No excuse for any programmer not to know it.

As for learning how to program in it securely, might as well give up before even starting.

This is how I know you don't know what you're talking about. Anything that can be programmed in C can be programmed in Rust. Operating systems and drivers are already being worked on with nothing but Rust and assembly.

>>61311622

This hasn't been true for decades.
Your third point is true though.

>>61311663
>>61311678
>>61311695
when i say lower level i didn't mean you cannot do the same things with the rust, it's a compiled systems programming language, you can do anything with it.

what i mean is, C was designed in a way that making a compiler for it is easier than many other languages.

- it only has data types that directly corresponds to the underlying machine. it doesn't have string type for example. floating point is included later when the machines supported it.
- it only has operators that directly corresponds to the underlying machine.

there are many other design choices in C that compilers and underlying machines were in mind.

in that sense, C is lower level than Go or Rust or D. it's not about the ability, my point is that C is translated to assembly much easier and more straight forward.

>>61311789
Okay, so you're completely changing the definition of the term "low-level" (which has been used for a few decades) for your own benefit and expecting us all to go along with it. Got it.

>>61311785
>Not every language is compiled, moron.
i wrote that sentence this is in mind.

there are some hardware that can run java bytecode directly, but in almost any case, the native assembly code(machine code actually) is what's running.

for interpreted languages like python, it's the interpreter, for bytecode languages like java it's the VM, nevertheless eventually it's the cpu specific machine code that runs.

>>61311785
>Not every language is compiled, moron.
it still holds for interpreted languages. the interpreter has to send instructions to the cpu in the end

>>61308791
>Holy shit why?
Why not? It's language's fault for not having memoization, not theory

>>61311821
that's not true, the real definition of low level is how close programming languages abstractions to the underlying instruction set of cpu.

a programming language with string data type as primitive type and operator like + to concat strings is higher level by definition.

it was never about the ability.

I looked into the language because I thought the syntactical sugar would make low-level more fun, but it didn't matter much when all the foundational concepts in Rust are horrible to begin with.
