In software, the term "Scheduler" typically refers to a component responsible for managing the order and timing of task or process execution. In the context of Golang, it can be a system that distributes goroutines (lightweight threads) for execution, deciding when and which goroutine to start.

For example, Go's built-in scheduler manages switching between goroutines, ensuring concurrent execution without the need to manually manage operating system threads.

An example of a simple task scheduler in Go:

package main

import (
    "fmt"
    "time"
)

func task(name string) {
    fmt.Println("Start task", name)
    time.Sleep(1 * time.Second)
    fmt.Println("End task", name)
}

func main() {
    go task("A")
    go task("B")
    time.Sleep(2 * time.Second) // Wait for goroutines to finish
}

Here, the Go scheduler manages the execution of two goroutines in parallel.
