• JSX is easier to read and maintain

• JSX is compatible with all browsers

• JSX supports more features

What is the purpose of coding challenges in this course?

• To test your knowledge of JavaScript

• To improve your coding speed

• To practice writing and debugging JSX code

• To learn about new React features

What should you do if you encounter an error during a coding challenge?

• Skip the challenge and move on

• Ask for help immediately

• Ignore the error and continue coding

• Try to work through the error and learn from it

What is the first step in creating a new JSX template during a challenge?

• Compile the code

• Render the template

• Create a new variable for the template

• Add dynamic data
