The methods imported from 'react' do what?

• A. They don't deal with the DOM at all but are for pure React purposes, such as creating components or writing JSX elements
• B. They directly manipulate the DOM to render elements
• C. They handle network requests
• D. They provide browser-only features

Answer: (A)

The main idea is that the methods exported by React are for building UI descriptions, not for manipulating the DOM directly. They provide the building blocks you use to define components and elements—things like creating elements (which JSX compiles to) and using or defining components and hooks. The actual work of updating the browser’s DOM is handled by React DOM, a separate package that renders your React elements into the DOM. So these React methods are about describing what the UI should look like in a declarative way, not about performing direct DOM operations. The other options miss this distinction: DOM updates aren’t done by the core React toolkit, network requests aren’t React’s responsibility, and React isn’t limited to browser features since there are other renderers like React Native.
