Get & Populate Items

The video tutorial covers the process of fetching data for an application, starting with hardcoded data and potentially upgrading to API data. It explains creating a 'get items' method in the item controller, initializing the application, and logging items. The tutorial then focuses on using the UI controller to populate a list with items, looping through items using template strings, and inserting generated HTML into the UI. It also introduces creating UI selectors for efficient code management and scalability. Finally, it hints at the next steps of adding meal items to the list.

What is the initial source of data in the application before integrating an API?

• Database

• Hardcoded data

• Local storage

• Remote server

What is the purpose of the 'get items' function in the item controller?

• To delete items from the list

• To update the user interface

• To fetch and return data items

• To save data to the database

When should the 'get items' function be called in the application lifecycle?

• After a user logs in

• When the application initializes

• When a new item is added

• Before the application closes

What is the role of the UI controller in the application?

• To manage data storage

• To handle user interface updates

• To fetch data from APIs

• To perform data validation

Which method is used to loop through items and append them to the HTML variable?

• forEach

• map

• filter

• reduce

What is the purpose of using template strings in the application?

• To create arrays

• To concatenate strings in a traditional way

• To include variables directly within strings

• To format numbers

What is the significance of the 'edit item' class in the HTML structure?

• It deletes list items

• It duplicates list items

• It allows editing of list items

• It styles the list items

Why is it important to use UI selectors in the application?

• To make the code more efficient and scalable

• To increase the application speed

• To enhance the visual design

• To reduce the number of lines of code

What is the benefit of storing selectors in a single object?

• It enhances security

• It speeds up the application

• It reduces memory usage

• It simplifies updating selectors across the application

What is the next step after having meal items in the list?

• Delete meal items

• Edit meal items

• Add a meal item with calories

• Sort meal items
