You learn js, then you learn a bit about ts and pick react/vue if you want to do frontend or nodejs if you're into backend. Then you do something basic, like a barebones twitter clone, weather app, etc. By the point when you're 80% done, you will know most important parts of the ecosystem naturally
After that, learning all the supporting libraries/frameworks is super simple since next is just superset around react, same for nuxt. Solid, svelte, fresh etc are just different flavors of react. Even vue is looking like react this days with composition api, simply because they nailed the simplicity and dev comfort. Average dev will never face weird js/ts parts or confusing libraries because most of their day to day job will be moving buttons and looking how to persist user basket in browser storage...
Sure there are a lot of libraries and ways to do stuff, but 90% of them are irrelevant, only-for-hobby or simply dead and unused since 2010. Knowing ts+(react|vue)+(vuex|redux-tk|mobx)+(styled|tailwind) will land someone a basic job where they can progress and expand their knowledge lol
Some of the specific communities are there but not here or barely alive here (like my phone's brand) so I'm visiting them from PC. Spez gets no moni because I'm always using unblock there though
Simple explanation: imagine an instance as an apartment house, where communities are apartments (where people can gather). You also have neighbor buildings (instances) with their own apartments. You can go and visit them freely if you want.
In that case, federation will be like a city I guess
I'm working on open source session replay tool (skipping the name not to promote it explicitly, but its quite easy to guess since our niche has not too many fully OS companies) as R&D/js library maintainer; at the same time I'm making my own lemmy app :)
Very fun and quite the opposite experience (going in deep with browser specs and API vs thinking about mobile UI and features)
I'd rather agree about mastadon, but not about Lemmy. I've seen people from (I assume) ~20 up to 40+. For example, I'm around 27 and I have few friends who were using Lemmy for almost a year now, they're in their early 20s.
Retirement age was raised to 64 here, but they also added new regulations and kind off point system where unless you were working since 18 you have to retire much later (around 68), but this protest is kind off died over months ago to be honest.
And now protests are:
2 police man killed 17 y.o who happened to be brown and Muslim because they first threatened him and he refused to comply, then tried to speed off away, almost hitting a pedestrian on his way. Policeman guys happened to have right wing associated tattoos as well, and even though the killed boy was someone with many criminal offences, shooting at him was not justified.
All these things are solving different problems and you absolutely don't have to use them if they complicate your current workflow.
I can't imagine making a high interval trading app, things like notion or figma without modern libraries.
jQuery only gets you so far before you will wake up in unmaintainable hell where your team has to re-invent the wheel
