JavaScript是世界上最流行的编程语言之一，这就是为什么有这么多基于该语言的框架的原因。其中最著名的莫过于Angular，它是一个为构建动态网站而设计的JavaScript框架。(JavaScript)
Angular JavaScript 框架
多年来，这个框架越来越受欢迎，因此，许多 Web 开发人员决定利用它所提供的优势。在撰写本文时，它还不是最好的工具，但它肯定会一次又一次地到达那里。让我们更详细地讨论一下：
- Angular JS 到底是什么？
- AngularJS的优点是什么？
- 在学习AngularJS(AngularJS)之前你需要知道什么？
1] Angular JS 到底是什么？
Angular被设计为一个开源框架，所以如果这是你的事，那么你来对地方了，伙计。
事情是这样的，你应该知道Angular是由两位Google工程师Misko Hevery和Adam Abrons 创建(Adam Abrons)的。自 2012 年发布以来，这家搜索巨头一直在定期维护该语言。这使得该框架获得了大量忠实用户，我们只希望它进一步发展。
需要注意的是，早在AngularJS出现之前，还有其他方法可以创建动态页面，但不幸的是，这些方法效率不够高。效率的缺乏为AngularJS(AngularJS)席卷 Web 开发者环境铺平了道路。
现在， AngularJS(AngularJS)如此成功的原因之一是因为它使用了被称为模型-视图-控制器(Model-View-Controller)( MVC ) 的架构。
为了让事情更容易理解：
- AngularJS结合了HTML和JavaScript。
- JavaScript然后接受用户输入的数据并将其发送给AngularJS
- 然后 Angular 使用输入数据来修改HTML
由于与HTML和JavaScript的绑定，两者之间的代码被同步为一个实体。

2] AngularJS(AngularJS)的优点是什么？
Web 开发人员迁移到AngularJS(AngularJS)的原因有很多，我们将讨论其中的一些。
令人印象深刻的双向数据绑定：因为AngularJS的架构能够绑定JavaScript和HTML，开发人员不需要做很多工作，因为两者的代码已经同步。
对指令(Directive)的支持：HTML文件功能通过框架使用指令进行扩展。为了启用指令，用户必须首先将 ng- 前缀添加到HTML属性中。如果你看下面，你可以看到一个代码示例，其中指令正在发挥作用。
<div ng-app="" ng-init="quantity=1;price=5">
Quantity: <input type="number" ng-model="quantity">
Costs: <input type="number" ng-model="price">
Total in dollar: {{ quantity * price }}
</div>
桌面(Desktop)和移动(Mobile)兼容：发现AngularJS能够相对轻松地在桌面和移动 Web 浏览器上运行应该不足为奇。这很重要，因为 Web 开发包括移动和桌面体验。
3]在学习AngularJS(AngularJS)之前你需要知道什么？
如果您没有编程知识，那么直接使用Angular进行编码没有多大意义。如本文所述，AngularJS是一个JavaScript框架，因此，您需要先学习JavaScript、HTML、AJAX和CSS。
希望(Hope)你觉得这很容易理解。
What is Angular JavaScript Framework in simple terms?
JavaScript is one of the most popular programming languages in the world, which is why there are so many frameworks out there that are based on the language. One of the best known is no other than Angular, a JavaScript framework designed for building dynamic websites.
Angular JavaScript Framework
This framework has risen in popularity over the years, and as such, a lot of web developers have decided to take advantage of what it has to offer. It is not the best tool at the time of writing, but it is sure getting there one day at a time. Let us talk about this in more detail:
- What is Angular JS all about?
- What are the advantages of AngularJS?
- What you need to know before learning AngularJS?
1] What is Angular JS all about?
Angular was designed to be an open-source framework, so if that is your thing, well, you’re in the right place, compadre.
Here’s the thing, you should know that Angular was created by two Google engineers, Misko Hevery and Adam Abrons. Since its release back in 2012, the search giant has been maintaining the language on a regular basis. This has allowed the framework to garner a lot of loyal users, and we only expect it to grow even further.
It should be noted that there were other ways to create dynamic pages long before AngularJS came on the scene, but unfortunately, these methods were not efficient enough. The lack of efficiency paved the way for AngularJS to take the web developer environment by storm.
Now, one of the reasons why AngularJS is so successful is because it uses the architecture known as Model-View-Controller (MVC).
To make things simpler to understand:
- AngularJS unites HTML and JavaScript.
- JavaScript then accepts data inputted by the user and sends it AngularJS
- Angular then uses the input data to modify HTML
Because of the binding with HTML and JavaScript, the code between the two is synchronized as a single entity.

2] What are the advantages of AngularJS?
There are several reasons why web developers have migrated to AngularJS, and we are going to discuss a few of them.
Impressive two-way data binding: Because the architecture of AngularJS is capable of binding both JavaScript and HTML, developers are not required to do a lot of work because the code from both is already synchronized.
Support for Directive: HTML files functionality are extended with directives via the framework. In order to enable directives, the user must first add the ng- prefix to HTML attributes. If you look below, you can see a code example where directives are in play.
<div ng-app="" ng-init="quantity=1;price=5">
Quantity: <input type="number" ng-model="quantity">
Costs: <input type="number" ng-model="price">
Total in dollar: {{ quantity * price }}
</div>
Desktop and Mobile compatible: It should come as no surprise to find out that AngularJS is capable of running on both desktop and mobile web browsers with relative ease. This is important since web development consists of both the mobile and desktop experience.
3] What you need to know before learning AngularJS?
Jumping directly into coding with Angular doesn’t make a lot of sense if you have no programming knowledge. As explained in this article, AngularJS is a JavaScript framework, therefore, you will need to first learn JavaScript, HTML, AJAX, and CSS.
Hope you found this easy to understand.
