Basically make `console.error` and `console.warn` behave like normal - when a component stack isn't appended. I need this because I need to be able to print rich logs with the component stack option and to be able to disable instrumentation completely in `console.createTask` environments that don't need it. Currently we can't print logs with richer objects because they're toString:ed first. In practice, pretty much all arguments we log are already toString:ed so it's not necessary anyway. Some might be like a number. So it would only be a problem if some environment can't handle proper consoles but then it's up to that environment to toString it before logging. The `Warning: ` prefix is historic and is both noisy and confusing. It's mostly unnecessary since the UI surrounding `console.error` and `console.warn` tend to have visual treatment around it anyway. However, it's actively misleading when `console.error` gets prefixed with a Warning that we consider an error level. There's an argument to be made that some of our `console.error` don't make the bar for an error but then the argument is to downgrade each of those to `console.warn` - not to brand all our actual error logging with `Warning: `. Apparently something needs to change in React Native before landing this because it depends on the prefix somehow which probably doesn't make sense already.
react
React is a JavaScript library for creating user interfaces.
The react package contains only the functionality necessary to define React components. It is typically used together with a React renderer like react-dom for the web, or react-native for the native environments.
Note: by default, React will be in development mode. The development version includes extra warnings about common mistakes, whereas the production version includes extra performance optimizations and strips all error messages. Don't forget to use the production build when deploying your application.
Usage
import { useState } from 'react';
import { createRoot } from 'react-dom/client';
function Counter() {
const [count, setCount] = useState(0);
return (
<>
<h1>{count}</h1>
<button onClick={() => setCount(count + 1)}>
Increment
</button>
</>
);
}
const root = createRoot(document.getElementById('root'));
root.render(<Counter />);
