The Complete React Developer Course (with Hooks and Redux) - Filtering Redux Data

The video tutorial explains how to filter and sort expenses data using a function called getVisibleExpenses. It covers the implementation of filtering logic based on text, start date, and end date, and explains the concept of timestamps. The tutorial also includes testing and debugging of the filtering logic, ensuring that the function works as intended.

What is the main goal of filtering and sorting expenses in Redux?

• To change the reducers and action generators

• To add new properties to the Redux store

• To display a subset of expenses based on filters

• To modify the Redux store directly

What arguments does the 'getVisibleExpenses' function take?

• Both the expenses array and filters object

• Only the filters object

• Neither expenses nor filters

• Only the expenses array

Which of the following is NOT a filter used in the 'getVisibleExpenses' function?

• Text

• Category

• Start date

• Sort by

What do timestamps represent in the context of filtering expenses?

• Seconds since the start of the year

• Days since the Unix epoch

• Milliseconds since January 1, 1970

• Years since 2000

How does the 'getVisibleExpenses' function handle undefined start dates?

• It throws an error

• It includes all expenses

• It filters out all expenses

• It only includes expenses with a start date

What method is recommended for checking if a string contains another string?

• indexOf

• substring

• includes

• match

Why should both strings be converted to lowercase when using the 'includes' method?

• To make the search case-insensitive

• To reduce memory usage

• To make the search case-sensitive

• To improve performance

What happens if the 'includes' method finds the search string within the target string?

• It returns false

• It returns true

• It throws an error

• It returns the index of the match

What is the purpose of setting 'text match' to true initially?

• To ensure all items are filtered out

• To prevent errors before implementing text filtering

• To include only items with matching text

• To sort items alphabetically

What is the expected outcome when the text filter is set to 'rent'?

• All expenses are shown

• No expenses are shown

• Expenses with 'rent' in the notes are shown

• Only expenses with 'rent' in the description are shown
