What is AngularJS?

AngularJS is a JavaScript-based open-source front-end web framework mainly maintained by Google and by a community of individuals and corporations to address many of the challenges encountered in developing single-page applications. It aims to simplify both the development and the testing of such applications by providing a framework for client-side model–view–controller (MVC) and model–view–viewmodel (MVVM) architectures, along with components commonly used in rich Internet applications.

Example:

What are the main differences between HTML and XHTML?

HTML:
• HTML stands for HyperText Markup Language and is the standard markup language for creating web pages.
• HTML is not case sensitive, meaning that it does not require the use of uppercase or lowercase letters.
• HTML elements are written using tags, which are enclosed in angle brackets.
• HTML is a static language, meaning that the code does not change when the page is rendered.

Example:

My Web Page

Welcome to my Web Page!

This is my first web page.

XHTML:
• XHTML stands for eXtensible HyperText Markup Language and is a stricter version of HTML.
• XHTML is case sensitive, meaning that it requires the use of uppercase or lowercase letters.
• XHTML elements must be written using tags, which are enclosed in angle brackets.
• XHTML is a dynamic language, meaning that the code can change when the page is rendered.

Example:

My Web Page

Welcome to my Web Page!

This is my first web page.

What is MySQL?

MySQL is an open-source relational database management system (RDBMS) used in web applications to store and retrieve data. It is a popular choice of database for use in web applications, and is widely used in combination with PHP.

For example, if you have a website that displays products for sale, you can use MySQL to store all of the product information such as product name, price, and description. You can then use PHP to query the database and display the product information on the website.

How does URL mapping work in Django?

URL mapping in Django works by mapping a URL pattern to a view. A view is a Python function that takes a web request and returns a web response.

For example, if you have a URL like ‘/articles/’, you can map it to a view called ‘articles_view’. This view would be responsible for handling the request and returning the appropriate response.

In Django, you would do this by adding a URL pattern to your project’s urls.py file:

urlpatterns = [
path(‘articles/’, views.articles_view, name=’articles_view’),
]

In this example, ‘articles_view’ is the name of the view we want to map to the URL ‘/articles/’. When a request is made to this URL, Django will call the ‘articles_view’ view and return the response.
