I'm a senior FE engineer in Singapore, been doing FE since 2000, here's what I think:
1. Job descriptions and interviews now are skewed towards "full-stack" or backend. Most interviews are lacking or outdated due to the fast and volatile nature of FE.
2. Literally no career progression if you're specialised in FE. Most BE or "full-stack" devs will be given a chance to become principal engineers, tech leads, engineering managers, CTOs, etc. I've seen folks with "FE Team Lead" titles but never goes beyond that.
3. FE is a subconsciously looked-down field. Neither a designer nor an engineer. Product/design team won't involve you in meetings (but will treat you like a code monkey). BE/"full-stack"/API engineers will think your job is easy and keep throwing business logic stuff to FE.
