Inline JavaScript in HTML: Don’t do it, unless you like really, really bad code
Blog post from Tabnine
Modern coding practices have evolved from manually writing inline JavaScript within HTML files to using more sophisticated frameworks and libraries like Angular and React, which offer structured and organized approaches to code management. Inline JavaScript, once common in the 90s, is now seen as outdated due to the potential for maintenance challenges, code duplication, and stability issues across multiple pages, especially when handled by different developers. While inline scripts can still be found in areas like Google Analytics and are useful for server-side HTML renderings, they are not recommended for maintaining clean, reliable, and readable code. Frameworks like Angular and React offer better alternatives by providing architectural setups that handle DOM manipulation and data management more efficiently, thus reducing the need for inline JavaScript and helping to prevent conflicts in state management. The shift towards API-based architectures further emphasizes the importance of clear demarcation between front-end and back-end, encouraging developers to adhere to framework rules to maintain application integrity and prevent potential weaknesses resulting from improper inline JavaScript usage.
