Building a ChatGPT AI with JavaScript - An OpenAI Code-Along Guide - Async Await Fetch OpenAI and ChatGPT Post Request P

The video tutorial explains how to set up and use API calls in JavaScript, focusing on asynchronous functions. It covers the basics of API integration, the difference between synchronous and asynchronous JavaScript, and how to implement async functions using the fetch library. The tutorial also details setting up POST requests and handling API responses, emphasizing the importance of proper error handling.

What is the primary purpose of using an API in an application?

• To improve the application's performance

• To connect the application to external services

• To enhance the application's user interface

• To reduce the application's code size

How does JavaScript handle tasks by default?

• In parallel

• Synchronously

• Randomly

• Asynchronously

Why is it important to use asynchronous functions when retrieving data from a database?

• To ensure data is fetched before the code execution completes

• To make the code run faster

• To reduce the amount of code needed

• To avoid using libraries

What is the main advantage of using the fetch library in JavaScript?

• It automatically handles all errors

• It allows for synchronous code execution

• It simplifies network requests without promises

• It increases the speed of API calls

What is the purpose of the async keyword in JavaScript?

• To make a function run faster

• To enable asynchronous operations

• To convert synchronous code to parallel

• To automatically handle errors

In a POST request using fetch, what is the role of JSON.stringify?

• To automatically handle server responses

• To convert a JavaScript object into a JSON string

• To parse JSON data from the server

• To set the request method to POST

What must be included in a POST request to avoid errors?

• A multi-threaded process

• A synchronous function

• A JSON object with the correct structure

• A valid URL
