There is no denying that AngularJS as a web development framework is gaining popularity.
Top firms that use AngularJS in their technology stacks are
It extends its syntax for constructing different application components by using HTML as a modeling language. Data binding and dependency injection functionality also aid in code reduction.
Less coding and powerful time-saving features have made AngularJS a buzzword in the web development world.
Why to choose AngularJS?
AngularJS has a plethora of useful features that entice web developers to learn it.
AngularJS also uses Directives, which is its way of adding additional functionality to HTML.
It is also an open-source framework that is fully free to use, and it is used by thousands of developers all over the world. It is distributed under the Apache License 2.0.
6 Essential Prerequisites for AngularJS
Next, we will introduce you to the most essential prerequisites to kickstart your coding journey on AngularJS. You’ll be able to create large-scale applications fluently and easily once you’ve mastered AngularJS.
There are six basic prerequisites to learn AngularJS. They are
#2 Typescript and ES6
AngularJS applications can benefit from TypeScript to boost refactoring and quality.
The latest versions of AngularJS use TypeScript, so existing TypeScript-based AngularJS apps can be easily transitioned to the latest versions.
HTML and CSS are the foundations for all front-end developers.
AngularJS allows you to use HTML as your template language and expand HTML’s syntax to articulate the components of your application simply and succinctly.
The majority of the AngularJS templates are handcrafted HTML. As a result, you must be familiar with HTML forms and tags such as ng-form.
Through developing new HTML constructs, AngularJS tries to reduce the impedance mismatch between document-centric HTML and what an application need. AngularJS uses a framework called directives to teach the browser new syntax.
To make a more appealing UI interface, you can use CSS when handcrafting the prototype.
By installing Node JS, we also get NPM, which is a command-line designed to download and manage Node packages. We use it to download the AngularJS framework along with the development and testing tools.
The NPM registry also stores the file that is submitted. Developers can get the resources they need to build apps from the NPM registry.
#5 Understanding of Model-View-Controller (MVC)
The Model-View-Controller (MVC) architectural pattern divides an application into three logical components: model, view, and controller. Each of these components is designed to handle unique aspects of application creation.
Model is the most important element of the pattern. It is the dynamic data structure of the application which is independent of the user interface. It helps indirectly managing the data, logic, and rules of the application.
The view is a map, diagram, or table which is a visual representation of data
The controller accepts input and transforms it to model or display commands.
MVC is a common industry-standard web development platform for developing scalable and extensible projects.
#6 Document Object Model (DOM)
The Document Object Model (DOM) is a cross-platform, language-independent interface that treats an XML or HTML document as a tree structure, with each node representing a part of the document as an object.
It is a logical tree that represents a text. Each branch of the tree terminates in a node, which houses objects.
DOM methods provide programmatic access to the tree; they can be used to modify a document’s structure, design, or content. Event handlers may be connected to nodes. The event handlers are called when an event is triggered.
#1 Additional Hacks
The following are some additional hacks that you need to know to make coding in AngularJS easier: These are the supplementary prerequisite for AngularJS that helps to achieve expertise for beginners.
- Design Principal
It is a design principle that divides a computer program into distinct parts, each of which addresses a different issue. AngularJS makes extensive use of the SOC concept. All of the controllers, directives, utilities, and factories in AngularJS are designed for SOC. It produces code that is leaner and more readable. When you use the SOC concept, the reusability improves as well.
Promises are nothing more than a series of callbacks. Any AngularJS service you call will be called asynchronously. When a response from a service callback is received, promises help to keep the response and take action as required.
One of the best things about AngularJS is that you can quickly write test scripts. Both Unit testing and Integration testing are supported by AngularJS.
These three prerequisites to learn AngularJS will help in improving efficiency.
As a web developer, you will need to learn new frameworks on a daily basis. AngularJS is a platform for developing large-scale, high-performance, and simple-to-maintain web applications, with a large developer following. The AngularJS architecture creates rich interactive features for a real-time experience in single-page applications.
Since AngularJS is commonly used by individuals and companies in every sector around the world, candidates with a strong understanding of the language have a lot of career options. We have tried to compile a list of the most important prerequisites for AngularJS in this article.
Working through the prerequisites mentioned in this article will be a great way to learn AngularJS!
