+/// Create a new error boundary component.
+///
+/// ## Details
+///
+/// Error boundaries handle errors within a specific part of your application. Any errors passed in a child with [`Throw`] will be caught by the nearest error boundary.
+///
+/// ## Example
+///
+/// ```rust, ignore
+/// rsx!{
+///     ErrorBoundary {
+///         handle_error: |error| rsx! { "Oops, we encountered an error. Please report {error} to the developer of this application" }
+///         ThrowsError {}
+///     }
+/// }
+/// ```
+///
+/// ## Usage
+///
+/// Error boundaries are an easy way to handle errors in your application.
+/// They are similar to `try/catch` in JavaScript, but they only catch errors in the tree below them.
+/// Error boundaries are quick to implement, but it can be useful to individually handle errors in your components to provide a better user experience when you know that an error is likely to occur.
