title: Will await keyword in javascript slow down the application?
body: <p>I am relatively new to NodeJS. I was wondering if the <strong>await</strong> keyword will slow down the entire javascript/nodeJS program? </p>
  
  <p>For example, </p>
  
  <p>If I have many express routers written on a single server file, and one router function calls the '<strong>await</strong>' for a promise to resolve, will all others routers and asynchronous functions stay on halt/paused until the promise is resolved? Or just that thread will be paused?</p>
  
  <p>In such a case the await call will cause performance issues to the Javascript program?</p>
