ng-repeat of Angular JS:-
It is used to display Array or JSON data similar to foreach loop of Java.
We will mostly bind tables, drop-down lists, and Listbox data using ng-repeat.
Syntax of ng-repeat
<tr ng-repeat="var in source"> <td>var</td> </tr>
Example of ng-repeat to bind data in the dropdown list :-
<!DOCTYPE html>
<html>
<head>
<title></title>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.6.9/angular.min.js"> </script>
</head>
<body>
<div ng-app="myApp" ng-controller="myCtrl">
<select ng-model="a">
<option ng-repeat="item in arr" value="{{item}}">{{item}}</option>
</select>
{{a}}
</div>
<script>
angular.module('myApp',[]).controller('myCtrl',function($scope){
$scope.arr = ["C","CPP","DS","JAVA",".NET","PHP"];
})
</script>
</body>
</html>

Q Another Example of ng-repeat of angular JS using JSON?
JSON means Javascript Object notation, it is used to display data using key=>value pair.
JSON Use [] and { } to store element.
[] ---> it contain multiple element
{} ----> Object
Single row ---> {'rno':1001,'sname':'xyz'}
Multiple row-----> [ {'rno':1002,'sname':'xyz'}, {'rno':1001,'sname':'xyz'}, {'rno':1001,'sname':'xyz'}, {'rno':1001,'sname':'xyz'}]

angular.module('myApp',[]).controller('myCtrl',function($scope){
