What does building for the web look like 5 years from now?

What is asynchronous code used for?​

examples of asynchronous operations:

  • fetching data from an API
  • loading external scripts
  • and handling user input with a delay

definition: non-blocking code, asynchronous operations allow other code to execute without waiting.

common asynchronous patterns like Promises, async/await, and callbacks. These are fundamental concepts for understanding and working with asynchronous JavaScript, and you need to be able to describe each pattern and its use cases.

What is your experience with PHP​

  • PHP's role, including its use in server-side scripting, templating, and data fetching.
  • how PHP specifically generates HTML. To fix this, you should describe how PHP code is embedded within HTML, how it can echo dynamic content, and how it can construct entire HTML structures programmatically.
  • how PHP handles form submissions. To fix this, you should explain how PHP accesses form data (e.g., using $_POST or $_GET), how it validates input, and how it processes or redirects after submission.
  • how PHP interacts with a database. To fix this, you should describe common methods like PDO or MySQLi, how to connect to a database, execute queries (SELECT, INSERT, UPDATE, DELETE), and fetch results.

How do you ensure a website is responsive across various devices and screen sizes?​

You correctly mentioned the use of media queries for responsive design.

You highlighted the importance of testing on different devices and emulators.

You did not mention the use of flexible grid layouts like Flexbox or CSS Grid, which are fundamental for creating adaptable layouts. To fix this, you should explain how Flexbox or CSS Grid can be used to arrange content dynamically based on screen size.

You omitted the concept of fluid images and videos, which are crucial for ensuring media scales correctly across various devices. To fix this, you should discuss how to make images and videos responsive, often by setting their `max-width` to 100% and `height` to `auto`.

You missed mentioning the viewport meta tag, which is essential for controlling the page's dimensions and scaling on mobile browsers. To fix this, you should explain the importance of including `` in the HTML head.

You did not discuss the mobile-first approach, which is a best practice for building responsive websites. To fix this, you should describe how starting design and development for smaller screens first, then progressively enhancing for larger screens, leads to better performance and user experience.
