title: Node.js and synchronization
body: <p>I am thinking about using Node.js for next project. But I stuck at some point related to thread  safety concept. How these issues are addressed(or need to take care) while implementing in Node.js ?</p>
  
  <p>I know JavaScript supports functional programming and this paradigm will address thread-safety. What are best practices to be followed here.</p>
  
  <p>Thanks</p>
