What is the recommended way for naming components?

  • Use a long name that includes the component's functionality
  • Use a name that is the same as the component's file name
  • Use a name that is the same as the component's parent folder
  • Use a simple name that describes the component
The recommended way for naming components in React is to use a simple name that describes the component. The name should be a noun or noun phrase that accurately represents the component's purpose. This makes it easier to understand and maintain the code, as well as to reuse the component in other parts of the application.

How do you access props in attribute quotes?

  • {props}
  • {someProp}
  • {this.props.someProp}
  • {this.props}
In React, you can access props in attribute quotes by using the "this.props" syntax and the name of the prop. For example, to access a prop named "someProp", you would use the syntax "{this.props.someProp}" inside the attribute quotes. This allows you to dynamically set attributes based on props, such as setting the value of an input field or the source of an image.

What is the purpose of push and replace methods of history?

  • To add or replace a new route to the history stack
  • To clear the history stack and start a new session
  • To navigate to the previous route in the history stack
  • To update the current route without adding a new entry to the history stack
The push and replace methods of the history object are used to add or replace a new route to the history stack. The push method adds a new entry to the history stack and navigates to the specified route, while the replace method updates the current entry in the history stack without adding a new one. These methods are commonly used for programmatic navigation and managing the browser history in React applications.

Why is DevTools not loading in Chrome for local files?

  • DevTools is not supported for local files
  • The browser security settings prevent DevTools from loading for local files
  • The React app is not running in development mode
  • None of the above
DevTools may not load for local files in Chrome due to the browser's security settings. To fix this issue, you can start Chrome with the --allow-file-access-from-files flag, which disables the security check for local files. Alternatively, you can run the React app on a local web server instead of opening the HTML file directly in the browser.
