Learn JavaScript from Scratch JavaScript for Everyone - Fetch API

The video tutorial introduces the Fetch API, highlighting its advantages over the outdated Ajax method. It explains the syntax of fetch requests, emphasizing code readability through proper indentation. The tutorial demonstrates using APIs, specifically the Star Wars and Pokémon APIs, to fetch data. It covers handling JSON data, including converting strings to numbers. The video guides viewers through creating a fetch request and logging data to the console. Finally, it outlines a final project where learners use Swappy.dev to randomly load a character, encouraging hands-on practice with the Fetch API.

What is one of the main benefits of using the Fetch API over traditional Ajax requests?

• It simplifies the code and reduces complexity.

• It requires more code to handle responses.

• It is only compatible with JSON data.

• It allows synchronous requests.

How does the 'then' method relate to the Fetch API?

• It cancels a fetch request.

• It is used to handle errors in fetch requests.

• It processes the response from a fetch request.

• It is used to initiate a fetch request.

Which of the following is a correct URL format to fetch data from the Swapi API?

• swapi.dev/3/api/planets

• api.swapi.dev/3/planets

• swapi.dev/planets/api/3

• swapi.dev/api/planets/3

What type of data format is returned by the Swapi API?

• CSV

• HTML

• XML

• JSON

What is the purpose of using 'response.json()' in a fetch request?

• To log the response to the console.

• To send data back to the server.

• To parse the response as JSON data.

• To convert the response into a string.

Which of the following is NOT a step in making a fetch request?

• Fetching the URL.

• Turning the response into JSON.

• Sending a POST request by default.

• Logging the data to the console.

What is the final project task mentioned in the video?

• Creating a new API.

• Building a random character loader from Swapi.

• Designing a new website layout.

• Developing a game using Fetch API.
