SolidJS
A framework that looks like React — JSX, components, hook-like primitives — but works entirely differently underneath. No virtual DOM. Created by Ryan Carniato; 1.0 shipped in 2021.
The key is that the component function runs exactly once. What it returns compiles to direct DOM instructions, and signals wire each value to precisely the text nodes and attributes that depend on it. When a signal changes only those points update — no component re-run, no tree diffing, no dependency arrays to keep correct. The result is top-tier benchmark numbers and a small bundle. The trap is that props must not be destructured, since the reactivity lives in getters. The signal model has been hugely influential: Angular, Vue and Svelte 5 have all gone the same way. SolidStart is the meta-framework.
