How can developers effectively troubleshoot issues with JavaScript links in PHP code?

When troubleshooting issues with JavaScript links in PHP code, developers should ensure that the correct path to the JavaScript file is specified in the link. They should also check for any syntax errors in the PHP code that may be preventing the JavaScript link from being properly rendered. Additionally, developers can use browser developer tools to inspect the network requests and see if the JavaScript file is being loaded successfully.
