What is the correct way to do setInterval in Node?

Question

Node.js

It is necessary to give a number to clients every 2 seconds. Is it right to do so?

setInterval(() => {
  const bitcoin_price = Math.random() * (6000 - 0) + 0;

  clients.forEach(resolve => {
    resolve(bitcoin_price);
  });

  clients = [];
}, 2000);

P.S. The return must be on the server side.

On one request it is possible to answer only once. Google about websocket, there is a completely different technology and the code will be different. But setInterval will be the same.
