AngularJS | angular.isString()

      

         Name: {{name}}
         


         {{isString}}
         


         Name: {{name2}}
         


         {{isString1}}
         


         Name: {{name3}}
         


         {{isString2}}

To run the above code, just go to your file and run it as a normal HTML file. You will see the following output on the browser window.

Observe that name and name2 are strings, whereas name3 is a key-value pair in the given code, which is why we got the output "$scope.name2 is not a String."
