To design and build a mobile application, web application, Android, or iOS, you must use a web application. Today, businesses also need web application development, so they need a JavaScript framework, and the Angular JS framework is one of the most popular JavaScript frameworks.
What is Angular JS?
Angular JS is an open-source framework for front-end development and single-page web applications. The framework was created by Google engineers Misko Hevery and Adam Abrons. It has been going on since 2012, when Google released AngularJS for the first time.
Before AngularJS, pages contained static HTML codes, and it was impossible to interact between them and users. There were other methods to make pages dynamic, but they were very complicated. After the release of AngularJS, creating these pages has become much easier and takes less time.
One of the features of AngularJS is using the Model-View-Controller (MVC) architecture used in web application development.
This type of architecture includes:
- Model: A data structure that manages information and receives input from a controller.
- View: displays the information inside the model to the user and transmits the user’s commands to the controller.
- Controller: communicates with other layers and updates the model.
In simpler terms, Angular JS combines JavaScript and HTML. JavaScript accepts user input and sends it to AngularJS, and AngularJS uses it to modify HTML.
Advantages of using Angular JS
AngularJS is popular among web developers for several reasons:
- Easy to learn: You can work with it by mastering HTML, CSS, and JS.
- Two-way data binding: JavaScript and HTML are synchronized in the AngularJS architecture. As a result, this framework saves developers time.
- Directives: Using directives, you can add tags.
- Code structure: AngularJS provides templates, which reduce code and save time. In addition, it makes it easier to modify or fix bugs in your programs.
- Testing: The framework has a set of unit tests that make testing easy and faster.
- Dependency injection: Whenever you need the commands you’ve defined, AngularJS provides them.
- Bright Future: To answer the question “JavaScript or Python: which is better for the future?” we must say that Angular has a bright future due to its functionality and popularity. This is because it is constantly updated and growing.
- Compatibility: AngularJS runs on most desktop and mobile web browsers.
Also, the salary rate for people who work in this field is relatively high. For example, the salary rate for a Java native per hour is about $56.70.
Before learning Angular JS
You should remember that AngularJS is a JavaScript framework. Consequently, you should understand the basics and concepts of the programming language before learning AngularJS.
To learn Angular JS, in addition to knowing HTML, CSS, and AJAX, it is necessary to know the basics of JavaScript. This will help you with:
- Make progress quickly.
- Know when to use formwork.
- And become a flexible and creative developer.
Duration of learning Angular
After we understand what Angular is, we will move on to the duration of learning Angular. We will examine the duration of learning in three levels: basic, intermediate, and advanced. The duration of learning is also useful for freelance Java developers, as they can understand how much time they have to spend learning to work with this framework.
Basic Angular framework learning:
To get familiar with the Angular framework, you should spend at least 15 to 20 hours and 70 to 80 hours practicing to get to know this framework and write small projects with it.
Intermediate Angular framework learning:
If you want to write larger projects with this framework, consider at least 50 to 70 hours of learning and 300 hours of practice. Of course, more practice makes a difference.
Advanced Angular framework learning:
If you want to master the Angular framework fully, you should consider at least 300 hours of useful time for learning. In addition, consider about 1500 hours for practicing the topics you have learned.
Steps to learn Angular
To learn Angular, you need to refer to the right resources and follow these steps:
First step: learning HTML and CSS
As you know, HTML and CSS are integral parts of web pages, and you must master these languages for everything you want to do on the front end (not the language directly, but the markup structures and user interface design). Therefore, to learn Angular, the first step is a clear and sufficient understanding of HTML and CSS. Many online resources and websites for learning programming languages like HTML and CSS exist.
Second step: Learning TypeScript
This language has been produced over the last few years and is based on ECMAScript 6, or ES6. ECMAScript 6 is the updated JavaScript version with various capabilities, including MVC design (class-oriented structure) and…
Now, why should we learn Typescript? Because the Angular framework is written in the TypeScript language, you must use TypeScript 100% during the implementation of your projects.
