What are the programming languages ??that are close to Go?

In recent years, the Go language has gradually emerged in the field of software development and has been favored by more and more developers. Although the Go language itself has the characteristics of simplicity, efficiency and strong concurrency, it sometimes encounters some limitations and shortcomings. Therefore, looking for a programming language that is close to the Go language has become a need. The following will introduce some programming languages ????close to the Go language and demonstrate their similarities through specific code examples.

1. Rust

Rust is a system programming language that focuses on security and concurrency. Like the Go language, it also supports concurrent programming. Rust's ownership system and borrow checker ensure memory safety while requiring no garbage collection. Here is an example of using Rust to implement concurrent computation:

use std::thread;

fn main() {
    let mut handles = vec![];

    for i in 0..5 {
        let handle = thread::spawn(move || {
            println!("Thread {} is running", i);
        });
        handles.push(handle);
    }

    for handle in handles {
        handle.join().unwrap();
    }
}

2. Swift

Swift is a programming language launched by Apple with modern syntax and powerful type inference capabilities. Similar to the Go language, Swift also supports multi-paradigm programming, including object-oriented and functional programming. Here is an example of using Swift to implement concurrent tasks:

import Foundation

let group = DispatchGroup()

for i in 0..<5 {
    DispatchQueue.global().async(group: group) {
        print("Task (i) is running")
    }
}

group.wait()

3. Scala

Scala is a multi-paradigm programming language based on JVM with It has powerful functional programming support and has concurrency mechanisms such as channels and goroutines similar to the Go language. The following is an example of using Scala to implement concurrent tasks:

import scala.concurrent.Future
import scala.concurrent.ExecutionContext.Implicits.global

object Main extends App {
  val futures = for (i <- 0 until 5) yield {
    Future {
      println(s"Task $i is running")
    }
  }

  Future.sequence(futures).onComplete(_ => println("All tasks are completed"))
}

Through the above example code, we can see that programming languages ????close to the Go language have similar characteristics in concurrent programming. They all provide simplicity and efficiency. and safe concurrency solutions, suitable for development needs in different fields. When choosing a programming language, developers can weigh various factors based on project needs and personal preferences to find the most suitable tool to achieve project goals.
