You can use "this" in the following example:

const dgram = require('dgram');
const message = Buffer.from('from raspberry pi 3');
const client = dgram.createSocket('udp4');
var count = 0;

function intervalFunc() {
  count++;
  client.send(message, 3001, 'localhost', (err) => {
    //client.close();
  });
  if (count == '5') {
    clearInterval(this);
  }
}
setInterval(intervalFunc, 1500);
