#frontend Prompts

Simulate a technical interview for a junior front-end developer position. Ask me questions about HTML, CSS, JavaScript, and a framework like React. Start with a simple coding challenge, like reversing a string.

Show me how to create a simple, self-contained Web Component for a custom button. The component should use a Shadow DOM to encapsulate its styles and markup. It should also have a `disabled` attribute that can be toggled. Use vanilla JavaScript (ES6 classes).

I am starting a new web project. It will be a highly interactive single-page application (SPA) with real-time data updates. Compare and contrast React, Vue, and Angular for this project. Recommend one and justify your choice based on performance, learning curve, ecosystem, and scalability.

Analyze the following HTML snippet for web accessibility (a11y) issues. Identify problems related to semantic HTML, ARIA attributes, color contrast, and keyboard navigation. Suggest fixes to make the component more accessible to users with disabilities.

What is WebAssembly (WASM)? Explain its purpose and how it works with JavaScript in the browser. What are the benefits of using WASM for web development? Provide an example of a use case where WASM would be a good choice.

Explain the problem of state management in large frontend applications. What is "prop drilling"? How do libraries like Redux or Zustand solve this problem? Describe the basic concepts of a global store, actions, and reducers (or their equivalents).

Design the UI for an AI-powered code generator. Elements: 1. Prompt input field with history and suggestions. 2. Preview window with mobile/desktop viewport toggle. 3. 'Code' tab with syntax highlighting. 4. Version history sidebar. 5. Modern glassmorphism effects and subtle radial gradients in the background.
