To make sure that you remove the event listener successfully in JS DOM, you need to provide the same Javascript callback function that was originally added as a listener.
To make sure that you remove the event listener successfully in JS DOM, you need to provide the same Javascript callback function that was originally added as a listener. However, the implicit conversion from a Scala function to a JS function creates a new JS function every time, so we would never get referentially equal JS functions if we used the Scala-to-JS conversion more than once. Therefore, we need to perform that conversion only once and save the result. This method encapsulates such conversion.
