Today, Angular JS has been one of the widely used front-end JavaScript frameworks for designing dynamic web applications. Now, coming to present times,

如今，Angular JS已经成为设计动态Web应用程序的广泛使用的前端JavaScript框架之一。 现在，来到现在

Today, however, if you are looking to create a dynamic web app, then, by all means, you will opt for a company providing Angular2 development services. Let’s see the difference between AngularJS VS. Angular 2 in detail.

但是，今天，如果您想创建一个动态Web应用程序，那么您一定会选择一家提供Angular2开发服务的公司。 让我们看看AngularJS VS之间的区别。 Angular 2详细。

角JS (ANGULAR JS)

AngularJS is a front-end, open-source web application framework based on JavaScript. AngularJS uses HTML as a template in the framework where data & expression are merged to create an expressive environment for developing web apps quickly. AngularJS uses the controller approach where the view communicates using a $scope.

AngularJS是基于JavaScript的前端，开源Web应用程序框架。 AngularJS使用HTML作为框架中的模板，在该框架中，数据和表达式被合并以创建用于快速开发Web应用程序的表达性环境。 AngularJS使用控制器方法，其中视图使用$ scope进行通信。

Angular JS的主要功能 (Angular JS Top Features)

MVC框架 (MVC Framework)

MVC stands for model view controller architecture of AngularJS is dynamic in nature. Here Model covers the data & logic part of the application, View covers the aesthetics of the app, the controller connects these two, & enables the apps to function together as a whole. That’s why all the components are built separately & combined later.

MVC代表AngularJS的模型视图控制器体系结构本质上是动态的。 这里的Model涵盖了应用程序的数据和逻辑部分，View涵盖了应用程序的美观性，控制器将这两者联系在一起，并使应用程序能够作为一个整体发挥作用。 这就是为什么所有组件都单独构建并随后组合的原因。

用户界面 (User Interface)

For creating user interface, AngularJS use basic HTML tags.

为了创建用户界面， AngularJS使用基本HTML标签。

减少编码，做更多 (Code Less, Do More)

One of the biggest benefits AngularJS provides you is less code required for creating the same functionality with AngularJS than with the jQuery libraries and data binding is a strong reason behind this.

AngularJS为您提供的最大好处之一就是，与使用jQuery库相比，使用AngularJS创建相同功能所需的代码更少，而数据绑定正是其背后的强大原因。

表达方式 (Expressions)

Two-way data binding: This helps in creating synchronization between the model and the view. The changes made in the model gets instantly reflected in the view, and the changes in the view get instantly reflected in the models. This is useful in creating SPAs.

双向数据绑定：这有助于在模型和视图之间创建同步。 在模型中所做的更改会立即反映在视图中，而在视图中的更改会立即反映在模型中。 这在创建SPA时很有用。

Generally, AngularJS expressions are written inside two curly braces. {{expression}} which are used for two way data binding.

通常， AngularJS表达式写在两个花括号内。 {{expression}}用于双向数据绑定。

过滤 (Filter)

AngularJS filter helps in creating the pagination system that filters the data array with respect to the given parameters. For example, suppose there is a data array that contains all the natural numbers less 7 i.e. [1, 2, 3, 4, 5, 6, 7].

AngularJS过滤器有助于创建分页系统，该分页系统针对给定参数过滤数据数组。 例如，假设有一个数据数组，其中包含所有自然数减去7，即[1、2、3、4、5、6、7]。

Now suppose a filter is applied that allows only numbers less than 6 to be added to the resultant array. Therefore, the resultant array will be [1, 2, 3, 4, 5]. This is possible by using the AngularJS filters.

现在假设应用了一个过滤器，该过滤器仅允许将小于6的数字添加到结果数组中。 因此，结果数组将为[1,2,3,4,5]。 这可以通过使用AngularJS过滤器来实现。
