Synchronous APIs.With synchronous APIs, the expectation is that data will be returned immediately. An API is usually synchronous when data or service availability, resources and connectivity are high and lowlat
it is best to use asynchronous APIs. Also, when some of your API requests have a longer execution time, it is good to consider expensive operations outside the request. So, the responses to these requests can be provided faster.
Step 2: Establish the API test environment.When you determined the functional scope of your API, the next step is setting up an API test environment which is usually the task ofDevOpsengineers. It requires the configuration of the servers, databases, and every resource the API interacts with,...
// Step 1: Define a function that takes a callback as an argument function fetchData(callback) { // Simulate an asynchronous operation (e.g., fetching data from an API) setTimeout(function () { const data = { message: "Data fetched successfully in Intellipaat!" }; // Step 3: Cal...

The Fetch API is a relatively new web browser feature but builds on older technologies such as AJAX. AJAX stands for Asynchronous JavaScript and XML. It was the first widely adopted technology to allow websites to send requests without needing to reload the entire page. Before AJAX, if you ...
Following is an example of using Async/Await in JavaScript to fetch data from the CoinDesk API endpoint for the current Bitcoin price. In this example, the fetchBitcoinPrice function is defined as an asynchronous function that uses the await keyword to pause execution until the API request is ...
Asynchronous JavaScript and XML (AJAX): Relies on using the JavaScript XmlHttpRequest object to replace just a part of the page as needed for each update. The use of HTTP headers increases the file size, reliance on half duplex communication means using more TCP channels, and the need of t...
This could include any type of content accessible via HTTP, including web pages, API responses, or even media types like images and videos. Upon payment, the server would send a 200 OK response with the requested resource or a 202 Accepted status for an asynchronous operation. ...
The below code is an example of an asynchronous test method using Swift’s new async/await syntax. The testWebLinkAsync method uses the URLSession API to download the webpage at the specified URL, and asserts that the response is an HTTP 200 OK status code. func testWebLinkAsync() async...
