Small modules are extremely versatile and easy to compose together in an app with any number of other modules that suit your needs.

One way to alleviate this configuration fatigue is by making configuration consistent and composable. That’s what Sprocket’s new “manifest.js” seeks to do.

Since you've been using Svelte for a few months after using React, haven't you been hit by the lack of composability in Svelte?Passing around components as variables is such a common pattern in React, and there's no good replacement in Svelte. The lack of dynamism in components and styles makes theming and crafting reusable components (outside of simple widgets) very tedious [1][2]. I'm genuinely curious how someone can come from React and not be bothered by it.

In these two languages, the "Function is a first-class citizen, which allows for aggregation of behaviors outside of the class.

simple & composable interfaces

On one hand Solid just provides a collection simple primitives like createState, createEffect, createMemo, etc.. These can be composed to create much more powerful behaviors.

I think hooks will be beneficial to the Svelte ecosystem, making sharing code for Svelte apps that solve common problems easier.

being able to compose multiple components' functionality via decoration (not creating new "combo" components or something) is more elegant, and something I wish React had.

Sounds like Mixins are on their way out

The whole point of directives is composability. First: you can apply a directive to any component, even components included from other libraries. Second: you can apply multiple directives to the same component. Directives are decorators, so it's not the same thing.

Arel’s ComposabilityInternally Arel functions on AST nodes and every time an Arel method is made, the nodes in the AST will be modified accordingly. This is an important nature of how Arel works — composability, so that it’s able to build queries in a flexible way. With this abstract representation, we are able to safely add different filters and operations to the same query and even combine queries regardless of its order. Arel is able to generate the correct SQL query from it.
