Learning Lodash 4.0 (Video 11)

This video tutorial guides viewers through adding a new recipe to an application, focusing on managing tags within a data store. It covers code modifications in the recipe routes file, optimizing Lodash usage, and handling new tags. The tutorial also includes testing the application to ensure the new tags are correctly integrated and affect existing components. Finally, it outlines the next steps for updating the API's recipe list endpoint.

What is the primary goal when adding new tags to the recipe application?

• To ensure all tags are unique and not duplicated

• To create a new tag for every recipe

• To add as many tags as possible

• To remove all existing tags

Which Lodash method is used to get the last element of an array?

• first

• last

• find

• remove

Why is chaining in Lodash not always necessary?

• It is optimized for multiple method calls

• It is only useful for single method calls

• It is not supported in all environments

• It makes the code longer

What does the Lodash 'remove' method do?

• Sorts elements in an array

• Removes elements based on a callback function

• Finds elements in an array

• Adds new elements to an array

How are new tags saved to the data store?

• Using a for loop

• By calling a save function

• Directly inserting into the database

• Using DB.push with a map iterator

What should you do after making changes to the recipe route file?

• Restart the computer

• Run NPM run start to start the API server

• Delete the changes

• Close the code editor

What is verified in the developer tools network tab after adding a new recipe?

• The application version

• The new recipe ID and tags

• The server status

• The list of all recipes
