AngularJS Reference 
 
AngularJS library written in JavaScript. Angular js reference file is given below.

  • ng-model directive help to bind the value in html control.the above solution we use "num1" it will contain the first input value."num2" contain the second input value.
  • ng-app directive define the angular js application.
  • The ng-init directive initializes application data.in this solution num1 and num2 assigned "0" or "Zero" value.so we get  "0" on the runtime in the both html textbox.
  • "*" Will help to multiple both input value inside the expression {{ num1 * num2 }}.
Output of the above solution..
