Introduction

Angularjs provides angular.forEach function that invokes the iterator function that iterates or loops through each item in an array or object.

Syntax

angular.forEach(object, iterator, [context])

object: The object interate over.
iterator: The iterator function or the code.
context: Object to become context (using this) for the iterator function. It is optional

angular.forEach(array, function (value, index) {
   //
});

Example

var employees = [];
var employee = {
  Id: '0012',
  Name : 'Devit',
  Age : 30
};

employees.push(employee);

employee = {
  Id: '0013',
  Name : 'Priti',
  Age : 24
};
employees.push(employee);

angular.forEach(employees, function (employee, i) {

  console.log('employee object');
  //Through value
  console.log(employee);
  //Through index
  console.log(employees[i]);

  console.log('employee Name');
  //Through value
  console.log(employee.Name);
  //Through index
  console.log(employees[i].Name);

});
