I think any of the major frameworks (React, Angular, Vue) would be a safe bet. They are and will be well maintained and documented.

Of course it also depends on what you’re building: if it’s simple you could go for old school technologies like jQuery and <script> tags. All those things will still work in 10-15 years time. (generally functionalities are only added to the web, not removed, which means websites from the 90’s should still work on modern day browsers)

I’m personally a React developer and I like that over the last couple of years there have been only a few (and very minor) breaking changes. Upgrading React on any project has not caused me any troubles, which is great.
