I was saying elsewhere on the thread - I am not suggesting that each should be turned into a runtime call. Instead, 'svelte.each()' callsites are easy to identify in the AST and transform in the compiler.
So the errors remain compile-time, not run-time.
- jestar_jokin 6y agoThe danger is that a developer will use `svelte.each()`, thinking it uses the same rules as normal JS syntax, but it turns out Svelte applies its own rules which _are_ slightly different (hypothetically). So the developer must remember a new rule: "JS rules when calling foo.each(), Svelte rules when calling svelte.each()". A little harder to remember. Having a unique non-JS syntax makes the distinction obvious. (Just playing Devil's Advocate here)
- jugglebird 6y agoThat's a pretty reasonable argument and I believe a big part of what makes hooks somewhat complex since they look like regular Javascript but can behave differently.
