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.

Why is it beneficial to break application code into multiple files using ES6 import and export?

• To make the code more complex

• To allow for better scalability and maintainability

• To increase the file size

• To make debugging more difficult

What is the first step in using an import statement in Webpack?

• Define a global variable

• Set up a new file and import it

• Create a new HTML file

• Modify the Webpack configuration

What is a named export in ES6?

• A way to export a single default value

• A way to export values without naming them

• A method to export multiple values by name

• A technique to import all values from a file

How do you import a named export in ES6?

• Using the 'require' keyword

• By specifying the export name in curly braces

• By using a wildcard import

• By importing the entire file

What happens if you try to import a named export with a different name?

• The import will be ignored

• The import will succeed without any issues

• The import will fail with an error

• The import will succeed with a warning

What is the correct way to handle multiple named exports?

• Use a different file for each export

• Export them as a single object

• Use a comma to separate them in the export statement

• Export them one by one

In the practical challenge, what is the purpose of the 'isAdult' function?

• To check if a person can vote

• To determine if a person is an adult based on age

• To calculate the age of a person

• To verify if a person can drive

What is the main goal of the practical challenge in the video?

• To create a foolproof logic for age verification

• To understand the global scope in JavaScript

• To practice setting up and using named exports

• To learn how to modify Webpack configuration

What is the significance of using the 'export' keyword in ES6?

• It allows variables to be used globally

• It enables the sharing of variables between files

• It is used to define functions

• It makes the code run faster

What is the key takeaway from the video regarding file isolation?

• Files can access each other's variables by default

• Variables are automatically shared between files

• Each file maintains its own local scope

• All files share a global scope
