Is it recommended to separate JavaScript code into external files for better maintainability in PHP projects?

Separating JavaScript code into external files is recommended for better maintainability in PHP projects. This practice helps in organizing code, improving readability, and facilitating code reuse. By keeping JavaScript code separate from PHP code, it also allows for easier debugging and updating of scripts. 

<!DOCTYPE html>
<html>
<head>
    <title>External JavaScript Example</title>
    <script src="script.js"></script>
</head>
<body>
    <h1>External JavaScript Example</h1>
    <button onclick="myFunction()">Click me</button>
