Modern JavaScript from the Beginning - Second Edition - Filter Items

The video tutorial demonstrates how to implement a filtering feature in JavaScript. It covers setting up event listeners for input events, capturing and logging user input, converting strings to lowercase for comparison, looping through items, and using the indexOf method to match input with item names. The tutorial concludes with displaying the filtered results in real-time.

What is the purpose of adding items like milk, eggs, and cheese in the initial setup?

• To showcase item addition

• To create a list of items to be filtered

• To test the sorting functionality

• To demonstrate item deletion

Which event is used to capture typing in the filter input?

• Click event

• Input event

• Focus event

• Change event

Why is it important to convert both input and item names to lowercase?

• To ensure case-insensitive comparison

• To save memory

• To improve performance

• To simplify the code

What method is used to loop through the list items?

• forEach

• map

• filter

• reduce

What is the purpose of using 'indexOf' in the filtering function?

• To remove duplicates from the list

• To find the position of the input in the item name

• To count the number of items

• To sort the items alphabetically

What display property is used to hide items that do not match the filter?

• block

• inline

• none

• flex

What happens when the input text matches an item name?

• The item is moved to the top

• The item is highlighted

• The item is displayed

• The item is deleted

What is the default display style for list items in this example?

• block

• grid

• inline

• flex

What is the result of typing 'AP' in the filter input?

• All items are shown

• No items are shown

• Only items starting with 'A' are shown

• Only items containing 'AP' are shown

What is the main advantage of using the input event for filtering?

• It is more secure

• It requires less code

• It is easier to implement

• It captures input changes in real-time
