He mentions this in the article. I agree that building a SPA can be a bit hard and it is not very wise to use in-experienced develpers (without mentoring/lead)

He mentions this in the article. I agree that building a SPA can be a bit hard and it is not very wise to use in-experienced develpers (without mentoring/lead) to do it all. I have started to think about frontend development as at least two different types and sometimes business people and organizations mixes the two with bad results. I see some devs coming from html+css with a little js background and then a need for devs with more experience of data structures, state management, async code, good architecture etc. Some devs has this but comies from the backend and might instead lack experience in js and js frameworks/ecosystems. I think more organizations need to look where they are, which devs they have and how they can help getting everybody getting better at advanced frontend programming.
