What's the best way to begin utilizing JavaScript as browsers implement it, while still ensuring support for browsers that are one or two versions older?

Imagine a scenario where Chrome and Firefox decide to include support for yield and other JavaScript.next features in their upcoming X and Y versions.

Is there official guidance from organizations like W3C on how to effectively utilize these features while ensuring compatibility with the previous versions of Chrome (X-1) and Firefox (Y-1)?

Answer №1

It is advisable to implement a new HTML, CSS, or JS feature only after ensuring that the majority of popular browsers (>90%) support it in their stable versions. Additionally, consider adding a notification prompting users to upgrade their browser if they do not already have the necessary support. While some features can be simulated, others cannot, so prioritize user experience and always aim to provide the best possible solution.
