What is the Global API in AngularJS?

by

Global API is the combination of global JavaScript function, which is used to perform tasks such as comparing objects, iterating objects, and converting the data.

There are a few common API functions like:

  • angular.lowercase
    It is used to convert a string to lowercase string.
  • angular.uppercase
    It is used to convert a string to uppercase string.
  • angular.IsString
    It returns true if the current reference is a string.
  • angular.IsNumber
    It returns true if the current reference is a number.
  • AngularJS does not have a specific “Global API” in the same way that some other frameworks or libraries might. However, it does have a global object called angular, which serves as the entry point for many of its features and functionality.

    The angular object provides methods and properties that are used for various tasks in an AngularJS application. For example, you can use angular.module to define a module, angular.controller to define a controller, and angular.directive to define a directive. The angular object essentially acts as a container for different components and services in AngularJS.

    Here’s a brief example:

    javascript
    // Define a module
    var myApp = angular.module('myApp', []);

    // Define a controller
    myApp.controller('MyController', function ($scope) {
    $scope.message = 'Hello, AngularJS!';
    });

    // Define a directive
    myApp.directive('myDirective', function () {
    return {
    restrict: 'E',
    template: '<p>This is my custom directive</p>'
    };
    });

    In this example, angular.module, angular.controller, and angular.directive are all part of the global angular object. However, it’s worth noting that AngularJS is an older framework, and its use has declined in favor of newer versions such as Angular (2+). If you’re starting a new project, you might want to consider using a more recent version of Angular
