What makes SolidJS different from other JavaScript frameworks, and is it worth your time as a developer in 2025?

As a software engineer myself, this framework caught my eye, not only because it looks like React, but rather for its fast performance. I love writing code, especially with React, but SolidJS offers something special that deserves attention.SolidJS has been gaining significant traction in the frontend development world. As developers seek alternatives to React and other established frameworks, Solid offers a compelling mix of performance and developer experience.Now let’s just dig deeper into how SolidJS is a very good and a solid choice for a frontend apps.

The Performance Advantage

First and foremost let’s talk about the performance advantage that SolidJS gives you as a Developer.SolidJS consistently ranks at the top of JavaScript framework benchmarks, often outperforming React, Vue, and Angular by significant margins. This isn’t just marketing — it’s measurable in real-world applications.The key to Solid’s speed lies in its compilation approach. Unlike React, which uses a virtual DOM and constant re-rendering, SolidJS compiles your components into efficient DOM operations that run once and then update only what’s needed.This architectural difference means that Solid applications typically run 5–10x faster than equivalent React applications, with smoother rendering and less jank during complex UI updates.

Fine-Grained Reactivity

Reactive by design

Solid’s reactivity system is built on fine-grained reactivity principles, similar to Vue’s Composition API but with even less overhead. Your UI updates automatically when data changes, without unnecessary re-renders.This approach eliminates the need for complex optimization strategies like memoization, useMemo, or shouldComponentUpdate that React developers often struggle with.In practice, this means your application logic becomes more straightforward. When a piece of state changes, only the DOM nodes that depend on that state update, not entire component trees.

So you can basically say that SolidJS is a super fast JavaScript framework that updates only what’s needed, making it perfect for building apps with great detail and control.
