AngularJS APIs are used for comparing, iterating and converting objects.Basic AngularJS API includes
  • angular.isString()
  • angular.lowercase()
  • angular.uppercase()
  • angular.isNumber()
1. angular.isString() It is used to check whether an object is a string or not.It returns true if the object is string otherwise false. Example:
<!-- Write HTML code here -->
<!DOCTYPE html>
<html>
  <head>
<script src=
</script>
  </head>
  <body>
  
    <div ng-app="gfg" ng-controller="gfgCntrl">
    <p>{{ object }}</p>
    <p>{{ apiRes }}</p>
    </div>
  
    <script>
      var app = angular.module('gfg', []);
      app.controller('gfgCntrl', function($scope) {
          $scope.object = "GeeksForGeeks";
          $scope.apiRes = angular.isString($scope.object);
      });
    </script>
  
  </body>
</html>

                    
Output: 2. angular.lowercase() It is used to convert all the characters of the string into lowercase characters. Example:
<!-- Write HTML code here -->
<!DOCTYPE html>
<html>
  <head>
<script src=
</script>
  </head>
  <body>
  
    <div ng-app="gfg" ng-controller="gfgCntrl">
    <p>{{ object }}</p>
    <p>{{ apiRes }}</p>
    </div>
  
    <script>
      var app = angular.module('gfg', []);
      app.controller('gfgCntrl', function($scope) {
          $scope.object = "GeeksForGeeks";
          $scope.apiRes = angular.lowercase($scope.object);
      });
    </script>
  
  </body>
</html>

                    
Output: 3. angular.uppercase() It is used to convert all the characters of the string into uppercase characters. Example:
<!-- Write HTML code here -->
<!DOCTYPE html>
<html>
  <head>
<script src=
</script>
  </head>
  <body>
  
    <div ng-app="gfg" ng-controller="gfgCntrl">
    <p>{{ object }}</p>
    <p>{{ apiRes }}</p>
    </div>
  
    <script>
      var app = angular.module('gfg', []);
      app.controller('gfgCntrl', function($scope) {
          $scope.object = "GeeksForGeeks";
          $scope.apiRes = angular.uppercase($scope.object);
      });
    </script>
  
  </body>
</html>

                    
Output: 4. angular.isNumber() It is used to check whether an object is a number or not. It returns true if object is a number otherwise false. Example:
<!-- Write HTML code here -->
<!DOCTYPE html>
<html>
  <head>
<script src=
</script>
  </head>
  <body>
  
    <div ng-app="gfg" ng-controller="gfgCntrl">
    <p>{{ object }}</p>
    <p>{{ apiRes }}</p>
    </div>
  
    <script>
      var app = angular.module('gfg', []);
      app.controller('gfgCntrl', function($scope) {
          $scope.object = "GeeksForGeeks";
          $scope.apiRes = angular.isNumber($scope.object);
      });
    </script>
  
  </body>
</html>
