CLEAN: Florencio Avalos stepped out of a rescue capsule and into history

The video tutorial provides an introduction to promises in JavaScript, explaining their purpose and how they function in asynchronous programming. It highlights the importance of promises in managing asynchronous operations and ensuring that code executes in a predictable manner.

What is the primary purpose of using promises in programming?

• To handle synchronous operations

• To increase execution speed

• To improve code readability

• To manage asynchronous operations

How do promises help in managing asynchronous tasks?

• By executing tasks in parallel

• By ensuring tasks are completed in order

• By providing a way to handle success and failure

• By reducing the number of lines of code

Which of the following is a key feature of promises?

• They are faster than callbacks

• They can only handle success scenarios

• They are synchronous by nature

• They provide a way to handle both success and failure

What problem can promises help prevent in programming?

• Memory leaks

• Syntax errors

• Infinite loops

• Premature firing of events

In what scenario would you most likely use a promise?

• When writing a for loop

• When declaring a variable

• When reading a file from disk

• When performing a simple calculation
