# Small Intro of Node:
Node - Runtime Enviornment for execting JS code, perfect choice for building RESTful API , for building I/O intensive Application
Node Apps are Single-threaded ,non-blocking or asynchronous in nature.
Node have 'global' in anologous to 'window' on browser and have things/internal modules to talk to OS, have filesystem to do read and write ops, and more.  

Avoid: 
  For CPU-intensive apps because more they have to wait for a work to be done more time user have to wait to get related data.
  
NPM to download and install 3rd-party libraries from the npm registry

  • Tells webpack WHAT (files) and Where to load for the browser; Compliments the Output property.
• Loaders
• webpack only understands JavaScript and JSON files. Loaders allow webpack to process other types of files and convert them into valid modules that can be consumed by your application and added to the dependency graph.
