What potential pitfalls should be considered when trying to use PHP-"Enumeration" in JavaScript?

When trying to use PHP "Enumeration" in JavaScript, one potential pitfall to consider is that JavaScript does not have built-in support for enumerations like PHP does. To work around this, you can create a JavaScript object that mimics the behavior of an enumeration by defining key-value pairs for each constant value. This allows you to achieve similar functionality in JavaScript as you would with PHP enumerations.

<?php
abstract class Color {
    const RED = 1;
    const BLUE = 2;
    const GREEN = 3;
}

echo Color::RED; // Output: 1
?>
```

```javascript
// JavaScript equivalent of PHP enumeration for colors
const Color = {
    RED: 1,
    BLUE: 2,
    GREEN: 3
};

console.log(Color.RED); // Output: 1
