"How to Fetch Data from the Web with JavaScript"

Introduction

As a programmer, you may often need to fetch data from websites using JavaScript. Fortunately, JavaScript offers various built-in methods for making HTTP requests to web servers, such as the fetch() method.

In this tutorial, we will guide you through the process of using the fetch() method to fetch data from the web with JavaScript.

Step-by-Step Guide

Step 1: Create an Empty Object for Search Results

Firstly, you need to create an empty object to store the search results.

let search_result = {};

Step 2: Use the fetch() Method to Send the Request

Next, you can use the fetch() method to send the HTTP request and fetch the data from the web.

fetch(`search ${name}`)

Step 3: Extract the Response Data in JSON Format

After you have sent the request, you need to extract the response data in JSON format with the .json() method.

.then(response => response.json())

Step 4: Map the Response Data to the Empty Object

Once you have extracted the response data in JSON format, you can then map the data to the empty object you created earlier with the .map() method.

.then(response => {
   this.search_result = response.map(x => {
       let result = {};
       Object.assign(result, x);
       return result;
   });
});

Step 5: Display the Search Results

Finally, you can display the search results in your web page by using the search_result object.

Conclusion

Fetching data from the web with JavaScript can be a challenging task for programmers. However, by following the step-by-step guide we have provided, you can easily utilize the fetch() method to fetch data from websites, extract the response data in JSON format, map the response data to an empty object, and display the search results on a webpage.

Happy coding!
