What is and Why Databinding? 

  • We want to generate and display dynamic contents 
  • Without a framework-level databinding, a developer himself/herself would be responsible for 
    • Pushing data values into the HTML controls 
    • Handling user actions, which triggers value updates 
  • Angular databinding framework handles all these for you 
    • All you have to do is to use proper databinding markup's in the template
