How to use JavaScript Fetch API to Get Data?

Introduction
In this post, we'll build a professional and interactive user data viewer that fetches data dynamically using APIs like DummyJSON and JSONPlaceholder This step-by-step guide will help you create a stunning UI using HTML, CSS, JavaScript, animations, and keyframes. Impress your interviewers or boost your project portfolio with this practical example.

1. Overview of APIs:
We will use two APIs for fetching user data:

  • DummyJSON: A versatile API providing mock user data with details like name, gender, company, and address. Explore DummyJSON API here.
  • JSONPlaceholder: Another excellent API for testing with mock user data. Check JSONPlaceholder API here.

2. Setting Up the Project:
Prerequisites:
Basic understanding of HTML, CSS, and JavaScript.
A code editor (like VS Code).
A modern web browser.
Steps:
Create a project folder and include the following files:
index.html
style.css
script.js
Link the CSS and JavaScript files in your index.html.

3. Building the User Interface:
We'll create a responsive UI with the following sections:

Header: Displays the project title.
Filters: Buttons to filter users by gender or department.
User List: Shows user names dynamically loaded from the API.
Popup: Displays user details when a name is clicked.
