What is Goroutine?

Goroutine

of Go programming

Goroutines in Go programming language are lightweight threads, which are used to run multiple tasks simultaneously (concurrency).

Important properties of

goroutines:

Lightweight:

• Goroutines use much less memory than normal threads.
• It is possible to run multiple goroutines simultaneously, because separate threads are not created for each one.

Independent Activity:

• Goroutines work independently.
• Each goroutine has its own stack and grows in size as needed.

Easy creation:

A function can easily be run as a goroutine using the
• go keyword.

Advantages of Concurrency:

• Multiple goroutines work together, thereby speeding up code.

Goroutine usage:

Goroutines can be used to perform multi-tasking, i.e. execute multiple tasks at the same time. For example:

• Data Processing
• Network Request
• complex calculation

Example:

<code class="language-go">package main

import (
    "fmt"
    "time"
)

func printMessage(message string) {
    for i := 0; i < 5; i++ {
        fmt.Println(message)
        time.Sleep(100 * time.Millisecond)
    }
}

func main() {
    go printMessage("Hello from Goroutine!")
    printMessage("Hello from Main Thread!")
}</code>

Output:
Messages from main thread and goroutine will be printed separately. They will not block each other.

Importance of Goroutine

Concurrency Facilitation:

• Multiple tasks can be easily executed simultaneously using goroutines.

Speed ​​and Efficiency:

• Being lightweight, thread management overhead is low.

Networking and Data Processing:

• Network requests, database access and background processes are made easier.

In short: goroutines are a simple, fast and lightweight way to perform multiple tasks in Go.
