Golang channel reading data

When reading channel when ,channel It does not close but continuously listens （for Cycle and intChan Turn on ）

package main

import (
	"fmt"
	"time"
)

// WriteData
func writeData(intChan chan int)  {
    
	for i:=1;i <= 50;i++{
    
		// Put in the data 
		intChan <- i
		fmt.Printf("writeData  Write data =%v\n",i)
		time.Sleep(500)
	}
	close(intChan) // close 
}

//readData
func readData(intChan chan int,exitChan chan bool){
    
	for  {
    
		v,ok := <- intChan
		if !ok{
    
			break
		}
		fmt.Printf("readData  Read the data =%v\n",v)
	}
	// Finish reading the data 
	exitChan <- true
	close(exitChan)

}

func main(){
    

	// Create two pipes 
	intChan := make(chan int,50)
	exitChan := make(chan bool,1)

	go writeData(intChan)
	go readData(intChan,exitChan)

	//time.Sleep(time.Second * 10)

	for  {
    
		_,ok := <- exitChan
		if !ok{
    
			break
		}
	}
}
