How to get the pid of forked child process NODE JS

I'm forking child process in node and my business logic requires me to call this fork process again and again.Issue is to clean up previous forked process before calling next one.Is there any way that i can get my forked process pid ,so we can store it and kill it on next run 

 const program = path.join(__dirname, 'test.js');
  var myProgram= fork.fork(program, [], {
  silent: true
});

fork will retrun a ChildProcess object. This object contains a bunch of properties including pid and kill.

You can use the kill method to conveniently 'kill' your subprocess 

  const forked = child_process.fork("path");

  forked.pid // 189...
  forked.killed // false

  forked.kill();

  forked.killed // true
