To make an HTTP request in JavaScript, you can use the built-in XMLHttpRequest object or the newer fetch() function. Here's an example of using fetch() to make a GET request:
This code sends a GET request to https://example.com/api/data, which returns JSON data. The fetch() function returns a Promise, which resolves to the Response object. We use the .json() method on the Response object to extract the JSON data. Finally, we log the data to the console. We also catch any errors that occur during the request.
If you want to make a POST request with data, you can pass an options object as the second argument to fetch(). Here's an example:
This code sends a POST request to https://example.com/api/user with the data object as the request body. We set the Content-Type header to application/json to indicate that the data is JSON-encoded. We use JSON.stringify() to convert the data object to a JSON string.
Once again, the fetch() function returns a Promise, which resolves to the Response object. We use the .json() method on the Response object to extract the JSON data. Finally, we log the data to the console. We also catch any errors that occur during the request.
Overall, making HTTP requests in JavaScript is a common task that can be easily accomplished with the built-in XMLHttpRequest object or the newer fetch() function.
