Method for nodejs to send out buzzer sound and of system alarm sound

In this paper, an example is given to describe the method of emitting buzzer sound (system alarm sound) by nodejs. Share it for your reference, as follows:

nodejs sometimes requires an alarm sound. Use the following code to call the system buzzer to sound

process.stdout.write('\x07')

Also attached is my own Pomodoro nodejs, which is actually a 25-minute countdown and then beeps

var FANQIE_TIME = 25;
function beep()
{
for(var i =0;i<20;i++)
{
process.stdout.write('\x07')
}
}
var startTime = new Date(); 
var needTime =startTime.setMinutes(startTime.getMinutes()+FANQIE_TIME);
function showTime()
{
var now = new Date();
var totalSecond = Math.floor( (needTime - now)/1000)
if(totalSecond<=0)
{
beep();
if(interVal)
{
clearInterval(interVal);
}
return;
}
var mm =Math.floor(totalSecond/60);
var ss = Math.floor( totalSecond%60);
console.log(mm+":"+ss);
}
var interVal = setInterval(showTime,1000);

I hope this article is helpful to everyone's nodejs programming.
