Why Do We Need In Angular Day 12

Lecture 12 : Why Do We Need In Angular


What is Angular :

  • Angular is an open-source front-end framework developed by Google for creating dynamic, modern web apps.

  • First introduced in 2009, the framework has gained huge traction over the years for eliminating unnecessary code and ensuring lighter & faster apps.

Why do we Need in Angular :

  • We have listed the reasons below :

1) Supported by Google :

  • The best part about it is Google’s Long-Term Support (LTS). This sheds light on Google’s plan to stick with it and further scale up the Angular ecosystem.

  • Google apps also use this framework and their team is very optimistic about Angular’s stability, Other Angular developers also get a golden opportunity to learn from certified professionals.

2) TypeScript :

  • Angular applications are built using TypeScript language, a superscript for JavaScript, which ensures higher security as it supports types (primitives, interfaces, etc.).

  • It helps catch and eliminate errors early when writing the code or performing maintenance tasks.

3) Declarative UI :

  • Angular uses HTML to define the UI of the application. HTML, as compared to JavaScript, is a less convoluted language.

  • HTML is also a declarative and intuitive language.

4) POJO :

  • With Angular, you don’t need any additional getter and setter functions. Since, every object it uses is POJO (Plain Old JavaScript Object), which enables object manipulation by providing all the conventional JavaScript functionalities.

  • You can remove or add properties from the objects, while also looping over these objects when required.

5) Easy Testing :

  • In Angular, testing is extremely simple. Angular.js modules has the application parts, which are easy to manipulate.

  • With module separation, you can load the necessary services, while effectively performing automatic testing. 

  • You don’t even need to remember module loading order if you follow “one file-one module” principle.

6) Simplified MVC Pattern :

  • Angular framework is embedded with original MVC (Model-View-Controller) software architectural setup. However, it is not according to the established standards.

  • Angular does not ask developers to split an application into different MVC components and build a code that could unite them.


  • Rather, it only asks to divide the app and takes care of everything else. 

  • Therefore, Angular and MVVM (Model-View-View-Model) design structure are quite similar.

7) Modular Structure :

  • Angular organizes code into buckets, whether it is components, directives, pipes, or services. Those who are familiar with Angular refer to these buckets as modules.

  • Modules make application functionality organization easy, segregating it into features and reusable chunks. 

  • Modules also allow for lazy loading, which paves way for application feature loading in the background or on-demand.

8) Code Consistency :

  • Any code base requires consistent coding. A writer knows how important consistency is in their content pieces.

  • We know if the content fails to resonate with the readers to a deeper level at any touchpoint, we are on a downward slope of lead conversions. Coding is no different.

  • Inconsistent coding increases the risks of delayed launches or elevated costs. Unlike it, consistent coding has several benefits, such as it makes sites easier to use and enables the use of templates or pre-defined code snippets.

Basic Concept In C Sharp Day 16

Lecture 16 : Basic Concept In C Sharp C Sharp : C#  (pronounced  see sharp , like the musical note C♯, but written with the number sign) is a general-purpose, multi-paradigm programming language encompassing static typing, strong typing, lexically scoped, imperative, declarative, functional, generic, object-oriented (class-based), and component-oriented programming disciplines. C# was developed around 2000 by Microsoft as part of its .NET initiative and later approved as an international standard by Ecma (ECMA-334) in 2002 and ISO (ISO/IEC 23270) in 2003. It was designed by Anders Hejlsberg, and its development team is currently led by Mads Torgersen, being one of the programming languages designed for the Common Language Infrastructure (CLI). The most recent version is 9.0, which was released in 2020 in .NET 5.0 and included in Visual Studio 2019 version 16.8. C-sharp musical note : " C sharp " was inspired by the musical notation whereby a sharp symb

VS Code In JavaScript Day 6

Lecture 6 : VS Code In JavaScript What is VS Code : Visual Studio Code is a lightweight but powerful source code editor which runs on your desktop and is available for Windows, macOS and Linux. VS Code was announced on April 29,2015 by Microsoft at the 2015 Build conference. Why did we build VS Code : Visual Studio Code combines the simplicity of a source code editor with power developer tooling, like IntelliSense code completion and debugging. First and foremost, it is an editor that gets out of your way. The delightfully frictionless edit- build- bebug cycle means less time fiddling with your environment, and more time executing on your ideas. IntelliSense : IntelliSense is a general term for a variety of code editing features including : code completion, parameter information, quick information, and member list. IntelliSense features are sometimes called by other name such as "code completion", "content assist", and "code hinting".

ASP.NET MVC Interview Questions Part - II Day 26

Image
Lecture 26 : ASP.NET MVC Interview Questions Part - II 1) How is the URL structure of MVC core ? URL structure of MVC core is controller name with action name. Example : localhost:1234/{controller}/{action name}. The "localhost:1234" is considered as a controller name. 2) If the view name is different than action name how to invoke it  ? If the view name is different from action name we have to write and the view in double quotes. 3) How do we define navigation using anchor tag ? The HTML <a> element (also called the anchor element), containing its href attribute, creates a hyperlink to other web pages, locations within the same page, location to a specified title of another web page, or to an email web page.  The <a> tag defines a hyperlink, which is used to link from one page to another. The navigations can be defined using anchor tag as <a href="/Controller name/Action name"></a>. 4)  How to pass mode
