Answers for "make node app sleep for a certain amount of seconds"

node sleep

// one liner
await new Promise(resolve => setTimeout(resolve, 5000));

// or re-usable `sleep` function:
async function init() {
  console.log(1);
  await sleep(1000);
  console.log(2);
}

function sleep(ms) {
  return new Promise((resolve) => {
    setTimeout(resolve, ms);
  });
}

sleep javascript

//Javascipt is asyncronous so you can't pause/block code execution
//You can delay doing something with setTimeout
setTimeout(function(){
 	alert("Sup!"); 
}, 2000);//wait 2 seconds
