Angular Basic, Features of Angular, Setup Angular Project



Today we are going to learn about Angular Basics 

Let's get start...


What is Angular

        -    Angular is TypeScript Based open-source front-end platform. 

        -    Using angular we can create our application on the web and mobile side.

        -    Angular is created and managed by Google.

        -    It provides some features like component, directive, module, services, and end to                 end tooling.

Features of Angular

1. DOM ( Document Object Model )

2. TS ( Type-Script )

3. Data Binding

4. Testing

1. DOM ( Document Object Model )

   - In Angular, we are using regular DOM.

  - Suppose we are updating 6 instances on the same HTML page.
    In that case, angular is going to update the entire tree structure of HTML tags.

 

2. TS ( Type-Script )

  - TypeScript is the superset of JS ( Javascript ).

 - In the browser, It’s compiled into Plan JavaScript.

 - TypeScript is created and managed by Microsoft. It provides some    features like Type,         class, async/await, etc...

 - Angular Build entirely in the TS ( type Script). 

 - Angular used TS ( TypeScript ) as a Primary Language.

 - If you want to install TS then you can install it using NPM like below.

npm install -g typescript

3. Data Binding

- Data Binding is provide communication between .ts to .html file

- In Angular, we have a total of 4 types of Data Binding.

1) Interpolation 

Like: {{}} 

2) Property Binding

Like: [value]

3) Event Binding

Like: (click), (change), etc..

4) Two-way data binding

Like: [(ngModel)]="fName"

 

4. Testing

-  Angular Uses the Jasmine-Karma Testing Framework to test the application.

- Jasmine Framework is provided to write different - different test cases.

-  Karma Framework work as a test runner for created test cases.

 

Setup Angular

 

Step 1:

You need to install Node and NPM in you're system 

Link:  https://nodejs.org/en/

 Step 2: Install Angular CLI

npm install - g @angular/cli

 

Step 3: Create Angular Project

 

ng new project_name

 

Step 4: Go to your project directory

 

cd project_name

 

Step 5: RUN Project ( Server )

 

ng serve

Different between ``===`` and ``==`` operators in JavaScript

Hello Guys, In this blog we are going to learn about "===" and "==" different with details understanding and examples. JavaScript operators that you might have stumbled upon as a developer include "===", "==". JavaScript's "==" operator is commonly utilized for loose comparison purposes.  It functions by converting both of the values to a common type and then comparing them for equality.  Here's an example: The comparison operator "==" transforms the value of "17" from a string to a number before determining if the values match.  Consequently, if both versions of the data share the same properties and values, the comparison is marked as valid and returns true. The results of the "==" operator can occasionally be surprising, including: The comparison returns true when the "==" operator converts the empty string to the number 0 and compares it to the number 0.  This can result in bugs, so

What is Pipes in Angular? Built in Pipes with examples and how we can create custom pipe using angular

Hello Guys, In this blog you're going to learn about Angular Pipes with in-built pipes and and customized pipes with details understanding. As an Angular developer, you often come across situations where you need to transform data before displaying it to the user. For instance, you might want to format a date, display a currency in a specific format, or filter a list of items based on some criteria. This is where Angular Pipes come into the picture. Angular Pipes are built-in features that allow you to transform data easily and efficiently. What are Angular Pipes? Angular Pipes are a built-in feature in Angular that allow you to transform data in the template. A pipe takes in a value or values and returns a transformed value. The transformed value is then displayed in the template. Angular Pipes are similar to filters in AngularJS. However, they are more powerful and flexible. Angular Pipes can transform data in a variety of ways, including formatting, filtering, sorting, and more.

What is Map() Method? explain with with examples

Hi Guys, In this blog we are going to learn about map() method in JavaScript with detail understanding and examples. Map() :-  The map() method is one of the most critical tools in JavaScript programming. Its objective is to apply a function to every element present in an array, resulting in a new collection of effects. The method is highly valued by developers, and in this piece, we will investigate this method, delve into its mechanics, explore its syntax, and provide practical examples. The new array containing results is generated by calling the map() method on an array with a callback function applied to each element. The callback function can be passed as an argument and is executed during the process. For the map() method, the syntax is established as follows: When using the map() method, the the current element being processed, the array that the method was called on, and the index of the current element are passed as arguments to the callback function. It is also possible to u
