Improve Code Maintainability by Avoiding Inline Event Handlers

JavaScript Analyzer

What is this warning?

Your HTML contains event handlers like `onclick="..."` written directly inside the tags. This mixes your page's structure (HTML) with its behavior (JavaScript), which makes the code harder to read, debug, and maintain. It's a practice that has been replaced by modern, cleaner techniques.

How to Fix It

The Problem

<button onclick="alert('You clicked me!')">Click Me</button>

The Solution

Separate your JavaScript from your HTML. Use `addEventListener` in your script file to attach events to elements.

<!-- In your HTML -->
<button id="myButton">Click Me</button>

<!-- In your JavaScript -->
document.getElementById('myButton').addEventListener('click', () => {
  alert('You clicked me!');
});

Why This Works

This separation of concerns is a core principle of good web development. It makes your code more organized, reusable, and much easier to manage as your project grows.
