which component connects javascript code with native apis in react native architecture?
o a. web engine

Explanation:

• First question: Hot reloading in React Native allows developers to see changes instantly without full recompilation, boosting productivity. Manual recompilation is time - consuming. React Native has JavaScript support and is not only native coding.
• Second question: Web apps are built using HTML, CSS, and JavaScript and run in a browser. Native apps use platform - specific languages. Hybrid apps have some web - like elements but are packaged differently. Cross - platform apps (like React Native) are not just based on running in a browser with HTML/CSS/JS.
• Third question: Web apps directly use web development skills like HTML, CSS, and JS. Native apps use different languages (e.g., Swift for iOS). Desktop apps have their own tech stacks. CLI tools are command - line based and not focused on reusing web dev skills for visual/app interfaces.

Answer:

1. B. Hot reloading
2. B. Web
3. C. Web apps
