SolidJS is a modern JavaScript library that introduces a unique approach to building reactive front-end applications. Unlike traditional frameworks that rely on a virtual DOM, SolidJS operates with fine-grained reactivity directly on the real DOM, offering exceptional performance and simplicity. At its core, SolidJS provides a compact set of reactive “primitives” that serve as building blocks for advanced functionalities. While its conceptual underpinnings may seem reminiscent of AngularJS’s use of ReactiveX, SolidJS delivers a developer experience closer to the lightweight simplicity of AlpineJS, but with a broader and more ambitious feature set. Recently reaching its 1.0 release, SolidJS has quickly…
