Hmm. Toughie. React kinda ate the web world well, so it's not a terrible bet that it'll keep it going for 3 years... If you like data layer / DB stuff (and if you're strictly a frontend dev) my suggestion is to just get comfortable with SQL / Postgres / SQLite, and just dbs in general, as that stuff has remained pretty darn stable for a while. Only really replaceable by even-simpler (though less versatile) approaches like giant plain key-value stores, file-system-style storage (NoSQL), or added versatility to Excel spreadsheets (lol it may be more viable to let companies just keep using those than moving to a DB nowadays just to let office workers use what's comfortable). I learned SQL 15 years ago and still glad to have it now surprisingly - though it's maybe sometimes more powerful than I need. But good value there. For frontend: JS, React, npm, docker containers, maybe Vue?... that's about as deep granularity as I'd go for predicting what'll keep another 3 years. Libraries, state management, all the tooling, etc etc - you'll probably relearn more than 3 times over during that... Welcome to (a hopefully well-paid) hell.
