+/// Start an interval which invokes `callback` every `ms` milliseconds
+///
+/// Currently, when `ms` changes, the previous interval is cleared, and starts with the new interval.
+/// This default behavior may change in the future, and may even be configurable.
+///
+/// # Examples
+///
+/// ```
+/// use xilem_web::{core::fork, concurrent::interval, elements::html::div, interfaces::Element};
+///
+/// fn timer(seconds: &mut u32) -> impl Element<u32> {
+///     fork(
+///         div(format!("{seconds} seconds have passed, since creating this view")),
+///         interval(
+///             1000, // in ms, when this changes, the interval is reset
+///             |seconds: &mut u32| *seconds += 1,
+///         )
+///     )
+/// }
+/// ```
+///
+/// # Panics
+///
+/// While `ms` is a `u32`, `setInterval` actually requires this to be a `i32`, so values above `2147483647` lead to a panic.
+/// See <https://developer.mozilla.org/en-US/docs/Web/API/setInterval#sect2> for more details.
