The video tutorial explains the importance of avoiding hardcoding URLs in your code to prevent redundancy and ease maintenance. It suggests creating a config folder to store constants like the API base URL, which can be exported and imported across the application. The tutorial also covers using template literals for dynamic variables in JavaScript and concludes with a functionality check to ensure everything works as expected without errors.

Why is it not advisable to hardcode the base URL in a JavaScript application?

• It makes the code run faster.

• It allows for easier debugging.

• It requires changes in multiple places if the URL changes.

• It improves the security of the application.

What is the purpose of creating a 'config' folder in a JavaScript project?

• To manage user authentication.

• To keep all CSS stylesheets.

• To centralize configuration settings like API URLs.

• To store all HTML files.

What is the benefit of exporting constants from a configuration file?

• It prevents the constants from being changed.

• It allows for the constants to be used globally across the application.

• It makes the application run slower.

• It hides the constants from the rest of the application.

How can you import a single constant from a file that exports multiple constants?

• By using angle brackets around the constant name.

• By using curly braces around the constant name.

• By using square brackets around the constant name.

• By using parentheses around the constant name.

What is the advantage of using template literals in JavaScript?

• They make the code harder to read.

• They allow for dynamic variable integration.

• They increase the file size.

• They are only used for styling.
