Learning Lodash 4.0 (Video 24)

This video tutorial covers the restructuring of a data store and REST API to handle recipe ingredients with specific amounts and units. It includes modifying API endpoints, testing API responses, and ensuring data integrity. The tutorial also introduces the use of Lodash methods for data manipulation and outlines the next steps in the project.

What is the primary focus of the initial part of the video tutorial?

• Deploying the application

• Authenticating users and managing form visibility

• Building a new user interface

• Creating a database schema

What new properties are added to the recipe ingredient data structure?

• Ingredient type and expiration date

• Amount and unit of measurement

• Supplier and cost

• Nutritional value and origin

Which Lodash method is used to filter out properties from an object?

• omit

• filter

• merge

• assign

What is the role of the assign method in the API modifications?

• To sort objects by a specific property

• To delete an object from the data store

• To merge properties into an existing object

• To create a new object from scratch

What is the purpose of the uniqueBy method in the context of this tutorial?

• To sort ingredients alphabetically

• To group ingredients by category

• To remove duplicate ingredients

• To calculate the total cost of ingredients

How are new ingredients saved to the data store?

• By manually editing the JSON file

• By using Lodash methods to manipulate arrays

• By calling a REST API endpoint

• By using a direct SQL query

What does the concat method do in the context of this tutorial?

• It appends new ingredients to the existing list

• It sorts the ingredients by name

• It removes duplicates from the list

• It combines two strings

Which method is used to find an ingredient by its title in the data store?

• find

• filter

• map

• reduce

What is the significance of the last method in the tutorial?

• It retrieves the first element of an array

• It removes the last element from an array

• It calculates the total number of ingredients

• It gets the last element of an array

What is the final step in testing the API response?

• Documenting the API endpoints

• Writing unit tests for the API

• Checking the response in a browser

• Deploying the API to a server
