Description

The Footer component uses a recursive setTimeout pattern for the welcome message animation, but only tracks the most recent timeout ID in a single variable.

function tick() {
  timeout = setTimeout(() => tick(), 5000)  // Overwrites previous ID
}
let timeout = setTimeout(() => tick(), 10_000)

onCleanup(() => {
  clearTimeout(timeout)  // Only clears the LAST timeout
})

When tick() schedules a new timeout, the previous timeout ID is lost before it can be cleared.

Impact

• Earlier timeouts continue to fire after component unmount
• Callbacks reference stale component state
• Closures prevent garbage collection
• Minor but cumulative memory leak
