In this article, we are going to learn about Object Extending Types in Typescript. In TypeScript, you can extend object types and interfaces using the extends keyword. This allows you to create new object types or interfaces that inherit properties and methods from one or more base types, including other interfaces. Extending interfaces is a fundamental concept in TypeScript, enabling you to compose complex and reusable type definitions....

Postman is a powerful tool for testing APIs, and its pre-request and post-request scripts allow you to customize requests and responses. it is an API(utility programming interface) development device that enables construction, taking a look at and altering APIs. It could make numerous varieties of HTTP requests(GET, POST, PUT, PATCH), store environments for later use, and convert the API to code for various languages(like JavaScript, and Python).

In this article, we will see how we can implement a QR Code Scanner with the help of HTML CSS & JavaScript. A QR code scanner will provide the user with two options to scan the QR code either by uploading the image file of the URL to be scanned or by using the camera of your system to scan the QR code and decode it. This application will show you an alert message with the decoded text of the QR code....
