What role do 'container' and 'presentational' components play in organizing React apps?

Containers handle data and logic, while presentational components focus on UI. This separation keeps code clear and organized.

What is the best practice for React component size?

A Avoid splitting components to reduce files

B Put all UI in one big component

C Use class components only

D Make components small and focused

Small, focused components are easier to manage, test, and reuse.

Where should you place related component files like styles and tests?

A In the same folder as the component

B In a separate global folder only

C Mixed randomly in the project

D Only in the root folder

Keeping related files together helps find and maintain them easily.

What do container components usually handle?

A Data fetching and logic

B Only UI rendering

C Styling only

D Routing only

Containers manage data and logic, separating concerns from UI.

Why prefer functional components with hooks over class components?

A They require more code

B They are slower

C Simpler syntax and easier to reuse logic

D Hooks are not supported

Functional components with hooks keep code simpler and more readable.

How can organizing components by feature help?

A Is not recommended

B Makes it easier to find and update related parts

C Slows down development

D Creates more confusion

Grouping by feature keeps related code together, improving clarity.
