Currently, I am implementing event listeners to determine if the device has touch capabilities. I would like these event listeners to remain active even after the page is reloaded.
Is it necessary to remove the event listeners using
removeEventListener('touchstart', myFunction)This code pertains to a VueJS application, specifically within the root instance. The event listeners are being added in the created section of the app.
It is crucial to remove event listeners before destroying the component that added them. If the component is removed without removing the event listeners, the associated functions may not be available when the event occurs. This can lead to errors that are difficult to trace and fix.
While this scenario may seem like a rare occurrence, it can result in pesky bugs that are hard to diagnose.
In Single Page Applications, failing to remove event listeners can also impact performance significantly.
Note: Make sure to only remove event listeners that were manually added through DOM manipulation (e.g., el.addEventListener()). Vue automatically cleans up its own events (@click, @my-custom-event, etc.).
