more developers trained in any tech stack
That is the primary argument my company used to justify forcing React. Do you know how many people we hired for their React experience? One. Everyone else was primarily backend or only had passing experience in React (not subject matter expert / does not know best practices). Meanwhile the rest of the team struggles to work in it (the frontend has become siloed) and very little of it follows best practice.
React is incredibly popular because so many companies use it. They are banking on Facebook's continued support and development, and an assumption that if Facebook is doing it then it must be right. Being rich does not automatically make one right. Having worked at a company that forced React on its developers against their wishes I can unequivocally say it's bad.
In any system the right action should be the default action. Query parameters should be parameterized by default, variables in HTML templates should be contextually escaped by default, and so forth. "Don't make me think". React is the complete opposite of that: It requires you to constantly think about the render loop (aka "Component Function"), it hides the fact there is an object behind the scenes containing the component state, the documentation is littered with "don't worry about this feature until after you have a performance problem, then come back here for the solution", it's very neat and tidy for tiny example projects but does not scale well as the project grows.

Compare that with a system like Vue or Lit, which is much more intuitive, does the right thing by default, and is easier for existing HTML/CSS/JS developers to grok at a glance.
The reactivity of Svelte leaves a lot to be desired. The only difference between a computed property and a mutable property is
let x =and$: x =, both of which are declared in the same top-level scope and doesn't provide much to distinguish them. The lack of reactivity on arrays and objects is a major foot-gun by default. The number of places they say "this looks weird, but don't worry it'll soon become second nature" in the docs shows that they acknowledge it's bad design to create code that is misleading or goes against the grain/standard for what behavior developers should expect (makes it confusing to work with and then use anything else, or vice versa).The
#awaittemplate directive is interesting; I'm not sure I agree it should be handled in the template instead of the script but if combined it would remove some boilerplateloading = true/falseanderror = 'message'variables from script scope.
