The Complete React Developer Course (with Hooks and Redux) - ES6 import/export

This video tutorial explains the use of ES6 import and export statements to modularize application code. It covers setting up webpack to handle multiple files, creating utility functions in separate files, and importing them into the main application. The tutorial emphasizes the importance of local scope and demonstrates how to use named exports and imports effectively. A challenge is provided to reinforce the concepts by creating a new file with named exports and importing them into the application.
