What is Angular?

Angular is a JavaScript framework that allows developers to create online, desktop, and mobile apps. Typescript, is a superset of JavaScript language that is used in the development of Angular applications, as well as HTML, CSS, and other markup languages. In JavaScript, the code of Typescript is converted and then displayed in the browser. One of the most popular JavaScript frameworks for developing web applications is Angular. To date, three popular versions of Angular have been released: Angular 1 (also known as AngularJS), Angular 2, and finally Angular 4.

AngularJS and Angular 2 are two very different frameworks. Angular 2 and Angular 4 do, however, they have many things common. Angular 4 also provides backward compatibility with Angular 2, which means that Angular 2 code will run in Angular 4.

You're probably wondering why Angular 3 was never launched. Internally, however, there were some versioning difficulties with the modules. As a result, the Angular team decided to delay the release of Angular 3 and instead focus on Angular 4. Angular 5 and 6 were recently launched, and Angular 7 is expected to be released in September or October 2018. Because Google has promised to enhance Angular twice a year, new versions of Angular are released on a regular basis. However, Angular 4 is currently the most popular and frequently utilized among them. Backward compatibility exists for all Angular versions from 2 onwards.

What is the advantages of angular?

There are a number of benefits to utilizing Angular, some of which are listed here.

Angular supports Single Page Applications

Single Page Applications are a form of web application that loads a single HTML page that is dynamically updated based on the user's interaction with the app. Single Page Applications, or SPAs, may interface with back-end servers without having to refresh the entire webpage in order to load data into the application. SPAs give a better user experience because no one like waiting for a whole webpage to reload. Angular is useful for developing SPAs, thus it's worth studying!

Two-way data binding

In Angular >=2.x, to implement the two-way binding ngModel directive is used. The main advantage of two-way data binding is that retrievals from (and updates to) the data store are practically automated. When the data storage is updated, the UI is updated as well.

Modularity in Angular

In Angular, modularity can be thought of as code arranged into "buckets." In Angular, these buckets are referred to as "modules." The code for the programme is broken down into a number of reusable modules. A module is a collection of connected components, directives, pipelines, and services. These modules can be mixed and matched to make a complete application.

Modules also have a number of advantages. Lazy-loading is one of them; it allows one or more programme functionalities to be loaded on demand. Lazy-loading, when utilized correctly, can greatly improve an application's efficiency.

Because enterprise applications can grow to be rather large, spreading the work among numerous teams can be difficult. The code can be kept organized with modules, and effective division of labour can be done while keeping code consistency.

Reduced coding

Many web developers aim to write code that is both short and effective. Angular supports the MVC (Model View Controller) architecture, which means that the developer only needs to split his or her code to fit into the MVC structure, and Angular will handle the rest. There is no need to write pipeline.

Declarative User Interface

Angular leverages HTML to define an application's user interface. HTML is more simple, declarative, and intuitive than Javascript. The presentational logic is separated from the imperative logic in a declarative user interface. We don't have to worry about the programme flow or the sequence in which the components on the webpage load. We may simply define the page's layout, making it clear where the data is connected and to what it is bound. The remainder will be handled by Angular.

Easy integration

Angular integration is implemented into a number of frameworks, including Ionic, Telerik's Kendo UI, Wijmo, and others. As a result, Angular makes it simple to integrate third-party functionalities. So, if you want to add some high-quality user interface components, you may do so quickly with any of the frameworks listed above!

Cross-Platform

Any of the following sorts of apps can be built with Angular:

Web apps: Angular may be used to construct web applications. Progressive web apps can also be created starting with Angular 5. These applications offer a high level of performance and may also be used offline.
Native mobile applications: Angular may be used to create native mobile applications.
Desktop applications: For Mac, Windows, and Linux, Angular may be used to construct desktop-installed applications.

Top 10 Apps and Websites Developed with AngularJS

Angular is used to build a number of major and well-known websites. The following are a few of them:

The Guardian
PayPal
Upwork
Netflix
YouTube for PS3
Lego
Freelancer
Weather
jetBlue

There is a high demand for Angular in the industry, which has resulted in a surge in Angular-skilled job opportunities. Another compelling reason to study Angular in 2020!

Which angular version is best for beginners?

Because AngularJS is so distinct from Angular versions 2 and up, many businesses prefer Angular version 2 or higher. Angular 5 and 6 were just released, and they're backwards compatible with Angular 2 and 4. Angular 2 and 4 are both solid candidates for developing enterprise applications with high code dependability criteria. Angular 4 applications, on the other hand, are smaller and faster than Angular 2 applications, and they employ TypeScript version 2.2, which is the most recent version of TypeScript. As a result, learning Angular 4 in 2018 makes sense. You can, however, learn Angular 5 or 6 as well.

Given the numerous benefits of using Angular and the high demand for this expertise in the market, learning Angular is unquestionably beneficial.
