How to understand SolidJS coming from React or Vue

If you are familiar with React or Vue and are looking to understand SolidJS, you’ve come to the right place. SolidJS is a declarative JavaScript library for building user interfaces and is gaining popularity among developers for its performance and simplicity. Here are some tips on how to understand SolidJS coming from a React or Vue background:

1. Declarative Syntax

Like React and Vue, SolidJS also uses a declarative syntax to define UI components. You can create components using functions and JSX, which makes it easy to build reusable and composable UI elements.

2. Reactivity

In SolidJS, reactivity is achieved through reactive primitives like stores and signals. These reactive primitives allow you to create dynamic UI elements that update in real-time when the underlying data changes. If you are familiar with React’s useState and useEffect hooks, you will find SolidJS’s reactivity model easy to understand.

3. Composition API

SolidJS also has a Composition API similar to Vue’s Composition API. With the Composition API, you can encapsulate logic into reusable functions and compose them within your components. This makes it easier to organize and manage the codebase of your application.

4. Directives and Reactive Attributes

Similar to Vue, SolidJS also supports directives and reactive attributes that allow you to manipulate the DOM and handle user interactions in a declarative way. Directives like `on:click` and `bind:value` make it easy to add interactivity to your components.

5. Performance

One of the key features of SolidJS is its performance optimization. SolidJS uses fine-grained reactivity to only update the parts of the UI that have changed, resulting in faster rendering and better overall performance. If you are coming from React or Vue, you will appreciate the performance gains that SolidJS offers.

Overall, if you are familiar with React or Vue, you will find SolidJS to be a powerful and intuitive library for building modern web applications. By understanding the core concepts of SolidJS, you can leverage its features to create efficient and performant UIs.
