How to Fix: Javascript removeEventListener not working

Q: How do I fix: 🔧 Proven Troubleshooting StepsMethod 1: Pass a Reference to the Function?

Step 1: Replace the function with a reference to it using an arrow function or `bind()`.

The event listener is not removed because the function passed to addEventListener and removeEventListener has a closure that captures the outer scope variables, including app.addSpot and app.addFlag. This means that when removeEventListener is called, it's actually removing the event listener for the original function, but the function itself still holds references to these variables.

Quick Answer: Pass a reference to the function instead of calling it, or use an arrow function which does not capture outer scope variables.

To fix the issue of removing the event listener not working, you need to ensure that the function passed to `addEventListener` and `removeEventListener` is the same.
