Sorry, but I cannot create an entire version of Pokemon Gold as a single HTML file with JavaScript enclosed in script tags. It would require complex game mechanics and numerous assets which cannot be accommodated in a simple text-based conversation. However, I can provide you with a basic example of a text-based game using JavaScript. Keep in mind that it won't be a fully-fledged game like Pokemon Gold, but rather a simplified version. Here's an example:
This is a basic framework for a text-based game where the player can navigate through different locations in the game world. The player enters commands like "go," "look," "cross," "enter," "exit," etc., to interact with the game. Remember, this is a simplified example and not a complete game. You can expand upon this framework by adding more locations, items, and actions to make it more engaging.
