Web Development Learning Series — Part 6 of 10 · Intermediate to Advanced React is useful when a page has several connected interactive views. The challenge is often deciding what the application needs to remember. This lesson builds a difficulty filter for a course catalog and keeps the state small. Use an existing React learning project or the official documentation's interactive editor. This example is a component, not a complete installation guide. You should already know JavaScript arrays, functions, and basic JSX.

Web Development Learning Series — Part 5 of 10 · Intermediate TypeScript can catch many mistakes before a program runs, but an API response is still outside your control. A server can send an unexpected value even if your editor says the variable is a Course. This lesson shows where static types help and where a runtime check is necessary. You need basic JavaScript objects, arrays, and functions. Run the examples in the TypeScript Playground or a project configured with the current TypeScript compiler and strict checking.

Web Development Learning Series — Part 4 of 10 · Intermediate A page that loads remote data needs more than a successful request. It needs to explain what happens while waiting, when the server fails, and when the response is not the shape you expected. This lesson adds a small API-driven course panel. You should already understand functions and DOM updates. The example uses a same-origin courses.json file so you can practice without an external service or an API key.

Web Development Learning Series — Part 3 of 10 · Intermediate JavaScript becomes easier to learn when each interaction has a clear job. This project filters a course list as the reader types. It teaches events, arrays, and DOM updates without a framework. The finished feature should handle three situations: a matching query, an empty query that shows everything, and a query with no matches. Decide those behaviors before writing the event handler.

Web Development Learning Series — Part 2 of 10 · Beginner to Intermediate A course catalog should remain readable when the browser is narrow, the text is enlarged, or a card appears in a sidebar. In this lesson, build a small catalog without hard-coding a separate layout for every device. You need basic HTML and a stylesheet. Start with three cards containing a title, a short description, and a lesson link. Use real course names so you can notice when a longer title breaks the layout.

Web Development Learning Series — Part 1 of 10 · Beginner HTML gives a webpage its structure. In this lesson, you will build a course landing page that answers three questions: what will I learn, what do I need, and where should I begin? You do not need a framework or a build tool to complete the first version. Our example is a small course called Web Foundations. Replace the sample content with your own topic, but keep the structure clear. A successful first page is useful before you add animations or a complex design.

You can add audio and video to an HTML page with the <audio> and <video> elements. This beginner project turns multimedia theory into a small lesson page with a recording, a demonstration video, and readable notes. This tutorial continues our introduction to the World Wide Web, HTML, and multimedia . You need a text editor, a browser, and short media files that you own or have permission to use.

Internet vs World Wide Web: the key difference The Internet is the network infrastructure that connects devices and networks. The World Wide Web is a service that uses that infrastructure to deliver linked pages and media through browsers. Email and other network services can use the Internet without being web pages. HTML describes page content, HTTP carries web requests and responses, and URLs identify resources. The History of the Internet ARPANET was an early packet-switching research network funded by ARPA. Its first connected hosts appeared in 1969. Research on connecting different networks later helped develop the Internet. The Internet Society history, written by Internet pioneers , explains this development and distinguishes ARPANET from separate RAND research on military survivability. Key milestones in the history of the internet include: 1969 : ARPANET's first message sent. 1989 : Tim Berners-Lee proposes the World Wide Web. 1991 : The first website goes live, laying the...

VR replaces the user’s view with a virtual environment; AR adds digital elements to a view of the real environment. A virtual lab can let a learner inspect a model, while an AR lesson can place labels over a physical object. Choose between them according to the task, available devices and accessibility needs.   In the world of entertainment , virtual reality (VR) and augmented reality (AR) are changing the game. They're making our multimedia experiences more immersive and engaging. But what are these technologies, and how will they change how we enjoy multimedia? VR takes you into a fully made-up 3D world, letting you explore new places and experiences. AR adds digital stuff to the real world, mixing the virtual with the real. These technologies are set to change entertainment , from games and movies to live shows. As VR/AR get better, we can make multimedia experiences that are more interactive and fun. How will these new technologies change how we watch and interact w...
