Comparing React JS and JavaScript to give you better clarity:
| Feature | React JS | JavaScript |
| Declarative UI | React uses a declarative UI, which means that you describe what the UI should look like, rather than how to update it. This makes code more readable and maintainable. | JavaScript does not have a declarative UI, so you need to write code that updates the DOM directly. This can make code more complex and difficult to maintain. |
| Virtual DOM | React uses a virtual DOM, which is a lightweight representation of the actual DOM. This allows React to efficiently update the UI only when necessary. | JavaScript does not use a virtual DOM, so it must update the actual DOM every time there is a change to the UI. This can be inefficient, especially for large or complex UIs. |
| Reusable components | React encourages the use of reusable components, which makes code more modular and maintainable. | JavaScript does not have a built-in concept of components, so it can be more difficult to create reusable code. |
| Performance | React is generally considered to be more performant than JavaScript, especially for large or complex UIs. | JavaScript’s performance can vary depending on how it is used. However, it is generally not as performant as React for large or complex UIs. |
| Community support | React has a large and active community, which means that there are many resources available to help you learn and use the framework. | JavaScript also has a large community, but it is not as focused on React as the React community. |
