What are potential pitfalls of relying on external scripts for website functionality?

Relying on external scripts for website functionality can introduce security vulnerabilities, slow down page loading times, and create dependencies on third-party services that may change or become unavailable. To mitigate these risks, consider hosting scripts locally, regularly updating them, and implementing proper error handling. 

// Example of hosting a script locally instead of relying on an external source
<script src="/js/custom-script.js"></script>
